How was the interview process? What was it like?
2 rounds after the take-home challenge. First round was mostly about technical stuff such as experiment design & measurement. Second round is more behavioral.
What technical questions were asked?
Modeling and ML knowledge, Probability, Statistics & AB Testing, Product Metrics and Measurement
What was one of your solutions?
For the measurement question, we basically need to understand that it's a local football team with strong local fanbase, so the effect is expected in that particular city. In addition, a proper A/B test setup is not possible. Therefore we do geo experiment (pick other cities with parallel trend as counterfactual). Another option is to simply compare YoY & MoM change, especially whenever there is a football match.
2nd and 3rd question can be answered just by looking at the formula for power & sample size calculation.
