It was a campus recruitment drive. First round was an online test with aptitude, logical reasoning and English sections. Maximum filtration happened in the first round. The recruiting team had come to our college for the further process. They taught us Logo programming, and conducted a test on the same. That was second round. Third and fourth rounds were personal interviews. They asked questions on area of interest in mechanical stream and some puzzles. All they are looking for is your approach towards a problem or puzzle.
