1st and 2nd rounds consisted of mcq based questions on cad/cam software and ansys tool and 3rd round was 1-1 interview and the mcq questions were of average difficulty and interview questions were also off average difficulty but dont expect a guy who has knowledge on this software to ask u questions , my interview was conducted by a HR and he didnt know about the software himself all he did was ask a bunch of questions for which he had answers before hand
