I got call from consultancy and short listed for process. There will be three rounds 1- aptitude { 1 general and 1 CAD) after that model test and last and third round of interview. Unfortunately I am failed at model test. If you have experience on IG and CATIA then u go or else u shouldn't go. I am working on AutoCAD and they said you have to give model test on CATIA or UG. Too difficult if you don't have hands on experience.overall aptitude is medium neither easy nor tough and model also OK OK but u need practice. As as I failed in model test I didn't know interview.
