Interview Prompt
A team chat product's admin view flags any day on which edited messages outnumber the ones left untouched. From the message log, return every field of every message posted on a flagged day.
Summary
Some days, more messages get edited than sent.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your SQL against a real database
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
