There was total 6 rounds of interview two rounds of online coding test and 3 rounds of interview based on data structures and algorithm and one round of interview is with the hiring manager.

First-round was a telephonic one, taken by an Engineering manager. He asked me about Design patterns, types, uses etc., general walkthrough of my resume. Next week, I was called for 1:1 round at their office. 4-5 rounds were taken one after another on the same day. Overall, the interviews were very difficult, but the experience was good.
