Had 1 phone interview with recruiter. Then 2 phone interview with data scientists(1 for technical machine learning concepts and the other one is more like open ended questions). Then I went onsite with 5 rounds of interview. 1st round: interview with data scientist. Open ended questions. He gave me some business questions and asked me how to solve it. 2nd round: interview with the PM in another team. Some questions about insurance pricing. 3rd round: interview with the hiring manager. I have to say I feel very offended by the hiring manager. He kept working on the laptop and he didn't even look at the whiteboard. He asked me the same questions 3 times and I repeated my answer 3 times. Then I knew he was not listening to me at all. This round is mostly about the projects that I work on. What metrics to use to measure the health of the business. 4th round: interview with data scientist. This round is technical machine learning problems. How to derive the regression coefficient. Ask questions about prediction and random forest. 5th round: interview with data scientist. Coding exercise. Leetcode easy level questions. My overall impression is that people in Uber are very busy and they are not very friendly(except for the recruiter). I really like Uber's data driven environment, but I don't like their work style.
