Interview Prompt

We want to see which users activated early. Surface the users who logged at least one session within their first year after signing up, showing the user ID, signup date, and how many sessions fell in that window.

Summary

Activated early. A good sign.

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
