How do you decide between Flow and Apex?

Direct Answer

I start with the complexity, maintainability needs, error handling requirements, and who needs to operate the solution after launch.

Detailed Explanation

A strong answer shows that the candidate understands both tool capability and team operating reality. Many interviewers want to hear that you are not choosing the most technical tool by default.

Why the Interviewer Asks This

The interviewer is checking judgment, not only product knowledge.

Weak Answer Warning

A weak answer says Flow is for admins and Apex is for developers, which is too shallow.

Stronger Answer Direction

Explain complexity, reuse, control, and maintainability tradeoffs.

Follow-up Question

When does a Flow-first design become a maintenance risk?
