Practice Example:

trigger AccountTrigger on Account (before insert, before update) {
    for (Account acc : Trigger.new) {
        if (acc.Industry == 'Technology') {
            acc.Type = 'Tech Company';
        }
    }
}

Resources:

Salesforce Trailhead SOQL Modules: Learn SOQL through interactive exercises.

5. Prepare for Behavioral Questions

Salesforce places a strong emphasis on its values, including Trust, Customer Success, Innovation, Equality, and Sustainability. Expect behavioral questions that assess your alignment with these values and how you work within teams.

Common Behavioral Questions:

"Tell me about a time you worked in a team to solve a challenging problem."
"Describe a situation where you had to handle a difficult customer and how you resolved it."
"How do you stay updated with Salesforce releases and new features?"
"Can you provide an example of when you demonstrated leadership in a project?"

How to Answer: Use the STAR Method (Situation, Task, Action, Result) to structure your responses:

Situation: Describe the context.
Task: Explain the challenge or goal.
Action: Discuss the actions you took to address the situation.
Result: Share the outcome and what you learned.

Example Answer: "In my previous role, we were tasked with migrating our customer data to Salesforce within a short timeframe (Situation). I took the lead on data mapping and worked closely with the data team to ensure no data was lost (Task). We built a detailed data migration plan, ran multiple tests, and engaged stakeholders throughout the process (Action). As a result, we successfully migrated the data ahead of schedule with no issues, improving data accuracy by 15% (Result)."

6. Prepare for Technical Interview Questions

If you are applying for technical roles (e.g., Salesforce Developer, Architect), you will likely face coding challenges, problem-solving scenarios, and system design questions. Prepare for:

Apex Programming Challenges: You may be asked to solve problems using Apex, such as writing a trigger, batch job, or controller.
Lightning Web Components (LWC) Questions: Be ready to discuss and demonstrate how to build responsive components using LWC.
System Design Questions: Expect questions on how to design scalable Salesforce solutions, integrate with external systems, or handle large datasets.
Scenario-Based Questions: Be ready to describe how you would solve specific business problems using Salesforce tools.

Example Technical Question:

"How would you write an Apex class to update related contacts whenever an Account is updated?"

7. Engage in Mock Interviews

Mock interviews can help you practice your responses, improve your confidence, and identify areas where you need to improve. You can do this with peers or use platforms that offer mock interview services.

Examples:

"How does Salesforce handle new feature rollouts, and how can I stay up to date with the latest changes?"
"Can you describe the team structure and how collaboration works within the Salesforce team?"
"What is the most challenging project the Salesforce team has tackled recently?"

9. Stay Updated on Salesforce Releases
