There were total 3 rounds. Firstly I got interviewed by two interviewers. There were very cool and asked me about basic concepts yet deep ones followed by an brainstorming analytical puzzle. In another round I faced a high post (somewhere around DOE) who first asked me about my first round,asked some conceptual yet basic questions and then asked me if I had any queries. Lastly I met a HR, who asked me about my expectation and the overall experience. And finally he told me that I am selected so this was it.
