Interview Prompt

A pipeline scheduler stores job windows as [start, end] intervals and needs to detect and merge overlapping runs. Merge any overlapping or adjacent intervals and return the merged list sorted by start time.

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
