Apex is a strongly typed, object-oriented programming language that allows developers to execute flow and transaction control statements on the Salesforce platform's server in conjunction with calls to the API. It is used to write custom business logic, triggers, and controllers for Visualforce pages.
How to Answer ItWhen answering, explain the purpose of Apex, its syntax, and provide examples of its use in real-world applications. Mention its integration with Salesforce's database and how it enhances functionality.
Triggers are pieces of code that execute before or after specific data manipulation language (DML) events occur, while Process Builder is a point-and-click tool that allows users to automate business processes without writing code. Triggers are more powerful but require coding knowledge, whereas Process Builder is user-friendly.
How to Answer ItUse the STAR method to structure your answer, focusing on a specific instance where you used either a trigger or Process Builder. Highlight the results achieved through your choice.
Best practices for writing Apex code include bulkifying code to handle multiple records efficiently, using proper exception handling, writing test classes to ensure code coverage, and following naming conventions for readability. Additionally, it's important to avoid hardcoding values and to use custom settings or labels instead.
How to Answer ItDiscuss the importance of each best practice and provide examples of how you have implemented them in your previous projects.
Governor limits are runtime limits enforced by Salesforce to ensure efficient use of resources. To handle them, I optimize my code by bulkifying operations, minimizing SOQL queries, and using collections to store data. I also monitor limits during development and testing.
How to Answer ItExplain specific strategies you use to avoid hitting governor limits and provide examples of situations where you successfully managed them.
Visualforce is a framework that allows developers to build custom user interfaces for Salesforce applications. It consists of a tag-based markup language and can be used to create pages that integrate with Apex controllers, enabling dynamic content and user interactions.
How to Answer ItDiscuss how you have used Visualforce in your projects, including any specific features or components you utilized.
