The overall process took place at our campus, since it was a part of our placement drive. There were 2 layers of segregation and quite unsurprisingly the first one was an online assessment. People who qualified were shortlisted for the 2nd round, which was the interview. The interview itself wasn't very hard. They asked basic Mechanical Engineering questions but the only difficulty was that they took 2 rounds of technical interview. The 1st round was quite basic but 2nd round was a tough nut to crack. Overall it wasn't very hard. Although I did fine in 1st round, I definitely screwed up grandly in the 2nd round.
