Advanced Interview Questions

Can you explain the Salesforce development lifecycle?

The Salesforce development lifecycle is a set of best practices and processes for developing custom applications on the Salesforce platform. It is designed to ensure that the development work is properly managed, tested, and deployed to production with minimal risk and disruption. The Salesforce development lifecycle typically involves the following phases:

Requirement gathering and analysis: This phase involves gathering and documenting the requirements for the custom application, and determining how it will be built on the Salesforce platform.
Design: This phase involves designing the custom application, including defining the data model, user interface, and business logic.
Development: This phase involves the actual implementation of the custom application, including coding, testing, and debugging.
Testing: This phase involves thoroughly testing the custom application to ensure that it meets the requirements and works as expected. This includes unit testing, integration testing, and user acceptance testing.
Deployment: This phase involves moving the custom application from the development environment to the production environment, and making it available to end users.
Maintenance: This phase involves monitoring the custom application in production, and making any necessary updates or bug fixes.

It is important to follow the Salesforce development lifecycle to ensure that custom applications are developed in a consistent and reliable manner, and to minimize the risk of problems in production.

What are the different deployment methods available in Salesforce?

As a Salesforce developer, you need to deploy your changes from one environment to another to keep the data and functionalities in sync. Salesforce offers several deployment methods that you can use to transfer your metadata changes between environments. These deployment methods are as follows:

Change Sets: Change Sets are the simplest deployment method available in Salesforce. They are easy to use and allow you to deploy metadata changes between related Salesforce organizations. You can use change sets to deploy custom objects, custom fields, validation rules, page layouts, etc.
Metadata API: The Metadata API is an advanced deployment method that uses a set of APIs to automate the deployment process. You can use the Metadata API to transfer metadata between environments in a programmatic way. This method is recommended for larger deployments or for cases where you need to automate the deployment process.
Force.com IDE: Force.com IDE is an integrated development environment that provides a graphical user interface for deploying metadata changes. You can use the Force.com IDE to deploy metadata changes between different environments, such as from a sandbox environment to a production environment.
ANT Migration Tool: ANT Migration Tool is a command-line tool that automates the deployment process. This tool uses XML scripts to deploy metadata changes between environments. It is a powerful tool that can handle complex deployments, but it requires a good understanding of the Salesforce metadata model.
Package Installation: Packages are collections of metadata that can be deployed as a single unit. Packages can contain a combination of custom objects, custom fields, validation rules, page layouts, and other metadata. You can install packages in a Salesforce environment using the AppExchange or by uploading the package directly to the target environment.

In conclusion, the different deployment methods available in Salesforce allow you to transfer metadata changes between environments with different levels of complexity and automation. You can choose the method that best suits your needs based on the size and complexity of the deployment, your level of experience with Salesforce metadata, and the resources available to you.

Can you discuss any best practices you follow for Salesforce development and deployment?

Here are some best practices for Salesforce development and deployment:

Use a version control system such as Git to manage changes to your Salesforce code and metadata.
Follow the Salesforce development lifecycle stages: analyze, design, build, test, and deploy.
Use a Sandbox environment for development and testing, and only deploy changes to Production after thorough testing.
Use a Continuous Integration/Continuous Deployment (CI/CD) pipeline to automate the deployment process and reduce the risk of errors.
Use source-driven development with Salesforce DX to manage your source code and make deployments easier and more reliable.
Follow best practices for Apex coding, such as bulkifying your code, avoiding SOQL queries inside loops, and using governor limits appropriately.
Use appropriate levels of testing, including unit tests, integration tests, and user acceptance tests, to ensure that all code changes work as expected and don’t negatively impact existing functionality.
Monitor your Salesforce org regularly for performance issues and make optimizations as needed.
Use permission sets and profiles to control access to your Salesforce org and its data.
Keep documentation up to date, including technical specifications, user manuals, and release notes, to ensure that everyone involved in development and deployment is on the same page.

How do you handle conflicts during a deployment?

As a Salesforce Development Lifecycle and Deployment Designer, it is important to have a well-structured and organized process in place to handle conflicts during a deployment. Conflicts can occur when two or more developers make changes to the same code or object in the same environment.

Here are the steps I follow to handle conflicts during a deployment:

Identify the Conflict: The first step is to identify the conflict by comparing the source and target orgs to find any differences in the code or objects. This can be done by using tools such as Change Sets, Ant Migration Tool, or version control systems such as Git.
Review the Changes: Once the conflict is identified, it is important to review the changes made by each developer to determine the best course of action. This includes considering the impact of the changes on the overall system and the business requirements.
Merge the Changes: In most cases, the changes made by different developers can be merged together to create a single, unified solution. This involves creating a new version of the code or object that incorporates all the changes made by different developers.
Resolve the Conflict: If the changes made by different developers cannot be merged, it may be necessary to resolve the conflict by choosing one version of the code or object over the other. This decision should be based on the business requirements and the impact of the changes on the overall system.
Test the Changes: After resolving the conflict, it is important to test the changes to ensure that they work as expected and do not cause any negative impact on the system. This may involve running unit tests, integration tests, and regression tests.
Deploy the Changes: Once the changes have been tested and approved, they can be deployed to the target org. This may involve using tools such as Change Sets, Ant Migration Tool, or version control systems such as Git.

By following these steps, conflicts during a deployment can be effectively managed and resolved, ensuring that the changes made by different developers can be deployed seamlessly to the target org.

Can you explain change sets in Salesforce and when they are used?

Change sets in Salesforce are a tool that allows administrators to deploy changes to an organization’s production environment. They are used to move metadata components such as custom objects, fields, and validation rules from a development environment to a production environment. This is an important feature of the platform, as it ensures that changes can be safely tested before they are rolled out to the wider organization.

Change sets are created in the development environment, where changes are made to the metadata components. The administrator then selects the metadata components they want to deploy and adds them to the change set. The change set is then sent to the production environment, where the changes are deployed.

When using change sets, it’s important to ensure that the changes are tested thoroughly in the development environment. This is because once the changes are deployed to the production environment, they are immediately applied to all users.

Change sets can also be used to deploy changes between different Salesforce organizations. This is useful for companies that have multiple organizations, as it allows administrators to easily share changes between these organizations.

In conclusion, change sets in Salesforce are a powerful tool for administrators to deploy changes to their organization’s production environment. They are used to move metadata components from the development environment to the production environment and can also be used to deploy changes between different Salesforce organizations.

Have you worked with version control systems like Git in Salesforce?

How do you monitor the progress and success of a deployment?

Monitoring the progress and success of a deployment is a critical aspect of ensuring that the deployment goes smoothly and that any issues are detected and resolved quickly. To do this effectively, you need to establish a set of metrics to track and a monitoring process that is reliable, automated and can give you real-time insights into the deployment. Here are the steps you can follow to monitor the progress and success of a deployment:

Define key metrics: The first step in monitoring a deployment is to define what you want to measure. Common metrics include availability, performance, usage, and error rates.
Set up monitoring tools: The next step is to set up monitoring tools that can track these metrics and provide you with real-time insights. This can be done through a combination of system-level monitoring tools, such as logs and performance monitors, and application-level monitoring tools, such as application performance management (APM) tools.
Automate monitoring: Monitoring should be automated so that it can run continuously and in real-time. Automated monitoring tools can be programmed to trigger alerts when certain thresholds are reached, allowing you to respond quickly to any issues that arise.
Review logs: Logs can provide a wealth of information about the progress and success of a deployment. Reviewing logs regularly can help you identify potential issues and track how they are resolved.
Test and validate: Regularly testing and validating the deployment is an essential part of monitoring progress and success. This can be done through automated testing and manual testing, both of which should be conducted regularly to ensure that the deployment is working as expected.
Analyze and adjust: Finally, analyzing the results of monitoring and testing can help you identify areas for improvement and make necessary adjustments to improve the deployment. This can include adjusting configuration settings, fixing bugs, or adding new features.

In conclusion, monitoring the progress and success of a deployment is an ongoing process that requires a combination of automated tools, regular testing and validation, and ongoing analysis and adjustment. By following these steps, you can ensure that your deployment goes smoothly and that any issues are detected and resolved quickly.

Can you explain how Salesforce implements security in deployments?

The Salesforce Development Lifecycle starts with defining the requirements and business objectives, which are then translated into user stories and functional requirements. The next step is to design the solution, which involves creating data models, user interfaces, and workflows. Once the design is complete, the next step is to build the solution, which involves coding, testing, and integrating with other systems.

Once the solution is built, it is time to deploy it to the production environment. Before the deployment, Salesforce implements several security measures to ensure that the data is protected and that the solution is secure.

One of the first security measures is to use sandboxes, which are isolated environments where the solution can be tested and validated before it is deployed to production. This helps to catch any security vulnerabilities before they reach the production environment.

Another security measure is to implement role-based access control, which restricts access to sensitive data and functionality based on the role of the user. This helps to reduce the risk of data breaches and unauthorized access to sensitive information.

During the deployment process, Salesforce also implements data encryption to ensure that data is protected when it is stored and transmitted. This helps to prevent unauthorized access to sensitive data, even if the data is intercepted during transmission.

Finally, Salesforce implements a continuous security monitoring program to ensure that the solution remains secure. This involves regularly checking for security vulnerabilities, updating security policies, and responding to security incidents.

In conclusion, Salesforce implements security in deployments through a combination of best practices, standard procedures, and security measures that help to ensure the protection of sensitive data and the security of the solution.

Have you performed deployments to Production and sandbox environments?

Deployment refers to the process of moving code or configurations from a development environment to a live environment for users to access. In software development, there are typically two main environments: production and sandbox.

Production environment refers to the live environment where the actual application or website is hosted and accessed by users. It is the final destination for code or configurations and is critical to the success of the project as it is where users interact with the application. Deployments to production environments must be thoroughly tested and carefully planned to minimize downtime and ensure a smooth transition.

Sandbox environment refers to a testing environment that is isolated from the production environment. This environment is used to test new features, configurations, or code changes before deploying to the production environment. Deployments to sandbox environments are often less critical than deployments to production environments and can be performed more frequently to test changes and ensure that everything is working as expected before deploying to production.

In summary, performing deployments to both production and sandbox environments is a critical aspect of software development. It ensures that changes are tested and validated before being deployed to the live environment, reducing the risk of downtime and ensuring a smooth transition for users.

Can you walk us through the process of testing and deploying customizations in a Salesforce project?

the process of testing and deploying customizations in a Salesforce project involves several steps. The following is a detailed explanation of the process:

Requirements gathering: This step involves understanding the client’s requirements and translating them into a functional design. This will determine what customizations need to be made to the Salesforce platform.
Development: In this stage, the customizations are built in a sandbox environment. This ensures that the customizations are isolated from the production environment, allowing developers to test and make changes without affecting live data.
Testing: This step is critical to ensuring that the customizations meet the requirements and work as expected. The development team will perform both unit testing and integration testing. Unit testing verifies that each component of the customization works as expected, while integration testing verifies that the customizations work together with other Salesforce components.
Deployment: Once the customizations have been tested and are deemed ready for deployment, the development team will create a change set and deploy the customizations to the production environment. A change set is a collection of components that are deployed as a unit to another Salesforce instance. This deployment process can be automated using the Force.com Migration Tool, which helps simplify the deployment process and reduce the risk of human error.
User Acceptance Testing (UAT): In this stage, the customizations are tested by the client or end-users to ensure they meet their requirements and expectations. UAT can be performed in a sandbox environment or in the production environment, depending on the client’s preference.
Release and Maintenance: Once the customizations have been deployed and tested, they are released to the client for use. The development team will also provide ongoing maintenance and support to ensure that the customizations continue to function as expected.

In conclusion, the testing and deployment process for customizing a Salesforce platform is a critical component of the Salesforce Development Lifecycle. Ensuring that customizations are thoroughly tested and deployed in a controlled manner is essential to ensuring that the platform remains stable and functional for the end-users.

Have you dealt with large data migrations in Salesforce? How did you approach the problem?

As a Salesforce Development Lifecycle and Deployment Designer, I have extensive experience in the design, development, and deployment of Salesforce applications. The Salesforce Development Lifecycle is a set of steps that ensure that a Salesforce project is developed and deployed successfully. The lifecycle includes the following stages:

Requirements gathering: This stage involves collecting the requirements from the business stakeholders to understand their needs and expectations.
Design: In this stage, the requirements are translated into a design that outlines the architecture, data model, and user interface of the application.
Development: In this stage, the actual coding of the application is performed. The developers write code that implements the design and meets the requirements.
Testing: This stage involves testing the application to ensure that it functions as expected and meets the quality standards.
Deployment: In this stage, the application is deployed to the production environment and made available to the end-users.
Maintenance: This stage involves ongoing support and maintenance of the application, including bug fixes and enhancements.

Regarding large data migrations in Salesforce, I have handled several projects that involved migrating data from legacy systems to Salesforce. In these projects, the approach I took was to first understand the data structure and the relationships between the data entities. Then, I created a mapping between the legacy data and the Salesforce data model to ensure that the data was being correctly translated.

Once the mapping was complete, I used the Salesforce Data Loader tool to bulk upload the data into Salesforce. I also used the Salesforce Apex Data Loader to write custom code that could validate and manipulate the data before uploading it. This allowed me to ensure that the data was in the correct format and met the quality standards.

After the data was uploaded, I performed various tests to verify that the data was correctly migrated and that it met the business requirements. I also worked closely with the business stakeholders to ensure that the data was correct and that they were satisfied with the results.

In conclusion, my experience in Salesforce Development Lifecycle and Deployment Design has allowed me to handle large data migrations in Salesforce with a structured and efficient approach.

Basic Interview Questions

1. What is Risk Management?

Risk management is the practice of identifying, evaluating, and addressing potential risks associated with a project. This is a proactive measure as risks may or may not materialize, but being prepared for them can prevent negative impacts if they do occur.

2. What are Sandboxes?

Sandboxes are separate environments that create copies of your Salesforce organization. They are used for development, testing, and training without compromising data and applications in your production org. Any operations conducted in a sandbox will not affect your Salesforce production organization. Different types of sandbox environments can be created based on your requirements for storage, copy configuration, and refresh frequency.

3. Why does Salesforce offers sandboxes and a set of deployment tools?

Salesforce provides sandboxes and deployment tools to enable you to isolate customization and development work from your production environment until you are ready to deploy changes. This allows you to test changes against copies of your production data and users, provide a training environment, and coordinate individual changes into one deployment to production.

4. What is a Developer Sandbox?

A Developer Sandbox is designed for development and testing in an isolated environment. It includes a copy of your production org’s configuration (metadata).

5. Describe a Partial Copy of Sandbox?

A Partial Copy Sandbox is intended for use as a testing environment, including a copy of your production org’s configuration (metadata) and a sample of your production org’s data based on a sandbox template. It is used for quality assurance tasks such as user acceptance testing, integration testing, and training.

6. How do you find the Sandbox ID of the org that you’re logged in to?

The Sandbox ID of your org changes with each sandbox refresh. Salesforce will replace the previous value with the new one wherever the org ID is used, including text values and metadata. To locate the ID of the org you are currently logged into, go to Setup, enter Company Information in the Quick Find box, and then select Company Information.

7. What do you mean by Sandbox Cloning?

Sandbox Cloning is the process of creating a sandbox by replicating an existing sandbox rather than using your production org as the source. This saves time by customizing a sandbox with data and metadata and then duplicating it. Multiple concurrent streams of work in your application life cycle are simplified with Sandbox Cloning. You can set up a sandbox for each type of work, such as development, testing, and staging. When you clone a sandbox, all of its data and metadata are copied to the new sandbox, and the cloned sandbox uses the same license type as its source org.

8. What is Salesforce Data Mask?

Salesforce Data Mask is a data security resource for Salesforce admins and developers that uses platform-native obfuscation technology to automatically mask sensitive data in any full or partial sandboxes. The masking process allows you to mask some or all sensitive data with different levels of masking based on data sensitivity. Once your sandbox data is masked, it cannot be unmasked.

9. What is a Package?

A Package is a container for something as small as an individual component or as large as a set of related applications. After creating a package, it can be distributed to other Salesforce users and organizations, including those outside of your company.

10. What are the two types of packages ?

Packages come in two forms: unmanaged and managed.

Unmanaged packages are used to distribute open-source projects or application templates to provide developers with the basic building blocks for an application. Once the components are installed from an unmanaged package, they can be edited in the organization they are installed in.
Managed packages are used by Salesforce partners to distribute and sell applications to customers. These packages must be created from a Developer Edition organization. Using the AppExchange and the License Management Application (LMA), developers can sell and manage user-based

11. Describe the benefits of Managed Packages.

Managed packages offer the following benefits:

Intellectual property protection for Apex
Built-in versioning support for API accessible components
The ability to branch and patch a previous version
The ability to seamlessly push patch updates to subscribers
Unique naming of all components to ensure conflict-free installs

12. Define Components.

A component is one constituent part of a package. It defines an item, such as a custom object or a custom field. You can combine components in a package to produce powerful features or applications. In an unmanaged package, components are not upgradeable. In a managed package, some components can be upgraded while others can’t.

13. What are Attributes?

An attribute is a field on a component, such as the name of an email template or the Allow Reports checkbox on a custom object. On a non-upgradeable component in either an unmanaged or managed package, attributes are editable by both the developer and the subscriber. On an upgradeable component in a managed package, some attributes can be edited by the developer, some can be edited by the subscriber, and some are locked, meaning they can’t be edited by either the developer or subscriber.

14. What do you mean by Deploy?

To move functionality from an inactive state to active. The process by which an application or other functionality is moved from development to production. To move metadata components from a local file system to a Salesforce organization. For installed apps, deployment makes any custom objects in the app available to users in your organization. Before a custom object is deployed, it is only available to administrators and any users with the “Customize Application” permission.

15. When is Package Dependency Created?

This is created when one component references another component, permission, or preference that is required for the component to be valid. Components can include but are not limited to:

Standard or custom fields
Standard or custom objects
Visualforce pages
Apex code

16. Define Patch.

A patch is a way for developers to modify the functionality of components in a managed package while ensuring that subscribing organizations do not experience any visible changes. For example, developers can add new variables or alter the body of an Apex class, but they cannot add, deprecate, or remove any of its methods. Each package version is assigned a patch number to track patches. Patch Development Organization and Package Version are related terms.

17. What do you mean by Releasing an AppExchange package?

Releasing an AppExchange package is similar to releasing any other software program. Once published on AppExchange, anyone can install the package. Salesforce automatically applies the appropriate state to the package and its components, depending on the upload settings selected and where it is in the release process.

18. Can a developer refine the functionality in a managed package over time?

Yes, a developer can refine the functionality in a managed package over time by uploading and releasing new versions as requirements evolve. This may involve redesigning some of the components in the package. Developers can delete some, but not all, types of components in a Managed-Released package when upgrading it.

19. What situations may occur when you try deleting a package?

There are three possible scenarios:

A component added to a package cannot be deleted.
A component can be deleted, but it can only be undeleted from the Deleted Package Components page.
A component can be deleted and undeleted from either the Deleted Package Components page or the Recycle Bin.

20. What does an Action Attribute represent in a package?

If the Managed – Released package hasn’t been uploaded with the component deleted, the action attribute contains an Undelete link that allows you to retrieve the component

21. What is a Parent Object in a package?

A Parent object Displays the name of the parent objects a component is associated with. For example, a custom object is the parent of a custom field.

22. What changes can be allowed to custom fields in a package, after it is released?

The following changes are allowed to custom fields in a package after it is released.

The length of a text field can be increased or decreased.
The number of digits to the left or right of the decimal point in a number field can be increased or decreased.
A required field can be made non-required and vice-versa. If a default value was required for a field, that restriction can be removed and vice-versa.

23. What is API Access?

API Access is a package setting that governs the dynamic Apex and API access that s-controls and other package components have to standard and custom objects. Both the developer and installer can view the setting on the package detail page.

24. Can the developer of an AppExchange package restrict API access for a package before uploading it?

Yes, a developer can restrict API access for a package before uploading it to Salesforce AppExchange. Once restricted, the package components receive Apex and API sessions that are restricted to the custom objects in the package. The developer can also enable access to specific standard objects and any custom objects in other packages that the package depends on.

25. What is Default Unrestricted setting for API Access?

The Default Unrestricted setting gives package components the same API access to standard objects as the logged-in user when the component sends an API request. Apex runs in system mode, and unrestricted access grants Apex read access to all standard and custom objects.

26. What is Environment Hub?

The Environment Hub is a feature that allows users to connect, create, view, and log in to Salesforce orgs from one location. For companies with multiple environments for development, testing, and trials, the Environment Hub streamlines org management.

27. What can you do from the Environment Hub?

From the Environment Hub, you can:

Connect existing orgs to the hub with automatic discovery of related orgs.
Create standard and partner edition orgs for development, testing, and trials.
View and filter hub members based on selected criteria, such as edition, creation date, instance, origin, and SSO status.
Create single sign-on (SSO) user mappings for easy login access to hub members.

28. What is the Single sign-on (SSO) feature of the Environment App?

The Single Sign-On (SSO) feature of the Environment App simplifies the process of developing, testing, and deploying apps by allowing an Environment Hub user to log in to member orgs without having to re-authenticate. SSO can be set up by defining user mappings manually, using Federation IDs, or creating a formula.

29. Can you use the Environment Hub in Lightning Experience?

Yes, both Salesforce Classic and Lightning Experience support the Environment Hub.

30. What is an Apex Script?

After a subscriber installs or upgrades a managed package, app developers have the option to designate an Apex script to automatically execute. This feature allows for tailoring the package installation or upgrade according to the subscriber’s organization particulars. Examples of customization include populating custom settings, generating sample data, emailing the installer, informing an external system, or initiating a batch operation to populate a new field in a large data set.
