Welcome to your interview.
The question is on your right: SQL for Cohort Impact. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you use SQL to compare conversion or completion rates across onboarding cohorts before and after an operations change at Robinhood?
