An Apex trigger is a piece of code that runs when certain conditions are met within the Salesforce platform. It allows us to automate processes such as creating records or updating fields based on specific criteria.

I have experience writing both before and after triggers. Before triggers allow you to modify data before it is saved into the database while after triggers allow you to access the new record’s ID and perform additional processing. I also have experience working with bulk triggers which can process multiple records at once.”

22. Have you ever encountered any security issues while developing a Salesforce application and how did you handle them?

This question helps the interviewer assess your knowledge of Salesforce security and how you apply it to your work. Use examples from previous projects where you applied security measures to ensure that your application was safe from outside threats.

I have used VisualForce to create a variety of different user interfaces, from simple forms and data entry screens to more complex dashboards and reports. In each case, I was able to customize the page layout, styling, and behavior to meet the specific needs of the customer.

For example, I recently created a dashboard for an e-commerce company that allowed their customers to quickly view their order history, track shipments, and manage returns. The dashboard included several charts and graphs that were generated using VisualForce components. I also implemented a search feature so users could easily find the information they needed. Finally, I added various customization options so users could adjust the look and feel of the dashboard to match their preferences.”

25. Share your experience implementing Lightning components into customer-facing applications.

This question allows you to demonstrate your experience with a specific feature of Salesforce. It also gives the interviewer insight into how you approach projects and complete tasks.
