- SQL screen, case or take-home, stakeholder interview
Data analyst interviews test SQL, analytical thinking and communication. Expect a live SQL screen with joins, aggregation and window functions, questions on statistics such as averages, distributions and A/B test results, and a case or take-home where you analyse a dataset and present a recommendation. Interviewers care about whether you check data before trusting it, choose the right metric and explain findings simply to people who are not analysts. The strongest candidates finish every analysis with a clear recommendation and say how confident they are in it.
