It consists of 3 rounds. The first one is aptitude test, consisting of logical reasoning questions and a few others. The interview was smooth. Actually it wasn't like an interview, the interviewers were friendly :)

The first round was Aptitude round, we had 25 questions and time allotted was 75 minutes, The second round was technical round in which the questions were based on my resume, my subject knowledge, situational questions, general questions, etc. The last round was HR round in which they wanted to know if I was suitable to join the company, they asked about my future plans, strengths, weaknesses,. My advise is just be confident in whatever you speak, know what you're speaking about as they cross question you. Also be good at communication skills and showcase your personality in a way that they know you're keen to learn.
