Interview Prompt

The retention team wants to badge 'power users' who show up day after day without missing a beat. Given the activity log, find which users were active for 3 or more consecutive days. Watch out for duplicate entries on the same day.

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 python solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
