They will ask you to present a Project or mechanical engineering related design (this is where you try to impress them) then they will ask you some question to test your creativity and how you approach R&D.

Seemingly tedious interview process involving a written test, presentation and panel interview. The test seemed pretty easy with questions based more on logic thinking. For example, if a 16 ft drill is placed beside a boat and is submerged up to 3 ft, given that the water rises at 1 ft/h, what is the submerged height after 2 hours? The presentation involved showing a previous design project and was conducted quite informally, in fact my interviewers seemed surprised that I had brought slides along. As a fresh graduate, this would probably be one of the many projects done during university days. The panel interview was somewhat informal. I got asked questions such as: where do you see yourself in 5 years? What are your strengths and weaknesses? No technical questions were asked during this phase
