Interview Prompt
Our batch scheduler stores each job's start and end time as Unix epoch seconds, but the end time is only written once a job finishes, so jobs still running have none. For the jobs that finished, report how many whole minutes each one ran, alongside its job_id and job_name.
Summary
Promised by noon. Delivered at midnight.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your sql solution with real code execution
- Get instant feedback and a hire/no-hire decision
