Interview Prompt

The office manager needs to know how many conference rooms to keep unlocked each day. Given today's meeting schedule as a list of start/end time intervals, figure out the peak overlap to determine the minimum number of rooms needed so no two meetings in the same room overlap. Intervals are half-open: a meeting ending at time 10 does not conflict with one starting at time 10.

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
