First round was a one hour phone interview with the hiring manager, he asked me questions on my resume. Second round was a 2 hour SQL and Statistics test. Then onsite interview, met 5 people including one HR round. Overall really good experience.

I had to solve written test and then a phone screen. The written test and phone screen was extremely tough. You should be good at everything SQL, Statistics, Advertising Domain knowledge, linear programming, machine learning etc. I was able to clear the written test but the phone screen was extremely tough. I was asked about some difficult machine learning and statistics concept which I had never heard of. If you are a data scientist this position is for you but if you are analyst or just a programmer it is difficult to clear. Recruiters are really helpful and gives you a feedback time to time.
