First was a standard call with a recruiter. Then, an hour-long call with the hiring manager. During that call he gave me a SQL query to write and a python function to write. Second round was a phone interview with a VP where I talked about my general experience. Final round was an in-person interview consisting of another 1:1 interview with the hiring manager and a panel interview with 3 analysts. They did some more SQL whiteboard questions during the panel interview. Overall, the emphasis was on specific technical questions that heavily involved engineering concepts. It was pretty bizarre that they were asking questions like that to a data scientist.
