2 sections were there. 1st section of 20 questions 30 minutes and 2nd section of 10 questions 20 minutes. Questions were easy aptitude type.
In starting, questions on internship were asked. Then some basic questions of Mechanical engineering. Next, Puzzles were asked which were of moderate to difficult level.
Its timepass round. You just have to chat with the hr guy in with fluent English. Be honest in your answers(He may catch your lie). Some questions you need to know-
1. Why not going for higher study?
2. Why Dassault Systemes?
You can take time in interview and answer those questions.
Hard puzzle questions were asked. Probably questions were also asked which were difficult. One question of coding was asked in which approach was seen(Not to actually write the code).
