Interview Prompt

The QA team is profiling performance regressions and wants to see which device and operating system combinations produce the longest user sessions. For each session, show the user ID, device type, operating system, and session duration. Only include sessions that lasted longer than one thousand seconds.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your sql solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
