Interview Prompt

The marketing team wants a month-by-month read on push engagement across the year. For each month, find how many notifications were opened, busiest month first.

Summary

Push after push goes out. Some months, people actually read them.

How This Interview Works

1. Read the vague prompt (just like a real interview)
2. Ask clarifying questions to the AI interviewer
3. Write and run your SQL against a real database
4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
