2. Explain a time you resolved a performance issue in Salesforce. What steps did you take, and what was the result?

   This checks for problem-solving, familiarity with performance tools, and practical impact.

3. How do you approach writing unit tests for Apex classes and triggers to meet deployment quality standards?

   This assesses test coverage practices, use of test data factories, and commitment to maintainable code.

4. Give an example of a Salesforce integration you built. Which integration pattern did you use and why?

   This gauges integration design knowledge, choice of synchronous versus asynchronous patterns, and security considerations.
