the hiring took place at the university,which started with a wriiten IQ test and skill test which was of average difficulty followed by a 1:1 technical interview for those who got through those two previous tests, the technical interview will be tough since you are getting into core sector and the company is known to be a engineering conglomerate and labeled as one of the most respected companies,the topics of question varied from fluid mechanics to design of machines you can relate to me if you are a mechanical engineer and whole technical round lasted for around 40 min

technical skills communication and commitment test
