I appeared in campus placement for MECHANICL ENGG. the hiring process consists of four rounds, first online test at AMCAT ,then they shortlist candidates and then all the shortlisted candidates are selected for GD, technical interview,HR interview. one best thing about technip is that there is no ellimination round except the online test. one thing to keep in mind during GD is that the company focus mainly on team work and hence try to build up the gd along other teammates so you will get good score in gd,they notice the team work in particular and not just the leadership. the interview is average, in this they will ask your favourite subject,prepare at lest 3 core subjects and prepare SOM and fluid specially . even if you dont mention that they will ask questions from it.
