Very easy - 30 minute face to face, asked 1 or 2 technical questions but was more based on typical HR. Guys were really nice, didn't feel nervous at all

First is the aptitude round which checks your logical and reasoning skills. Then there is a technical round which contains really difficult questions based on mechanical engineering. After that, there is a group discussion (possibly on current topics). Then finally is one-on-one technical interview as well as HR interview
