The entire interview process consists of 2 rounds-
1. the first round is technical with questions mainly coming from the domain of SQL, DBMS and some Case studies on Uber operations.
2. Second round is HR round which consists of questions primarily from CV, Business case studies and guesstimates. You may encounter some curve balls in this round where the interviewer might ask you to solve some complex Uber specific cases. Just have a good structure and approach to such questions.
