First Round was an online test. They say they are testing your math skills but basically they are testing your excel/data handling skills. You need knowledge of pivot tables, etc and a good knowledge of Uber's Business model to be able to crack this round.
The second round was one person from HR called me to as a couple of questions like how to add more drivers, 'tell me about yourself' etc. and then she told me that someone else will contact me on Monday 3 pm.
The next round was pure HR for me. Why should we hire you, why did you leave your last company, who told you about this vacancy, etc. I was rejected in this round.
After the test, the second phone call was like 2 weeks after that.
