5 interviews.

(The last three are on the same day).

First interview is a screening about motivation. Then they give you a few weeks to prepare for the second interview.

Second interview is technical. Theoretical questions about C, C++, Matlab, and controls. Most of them are on Glassdoor.

Third interview is also technical, but more practical. They ask to compute derivatives, minimum square areas under curves, and to write Matlab functions, subfunctions, and nested functions (beware of the difference between the two last). In C and C++, they ask some tricky questions involving pointers, like char *a = "hello"; cout << a + 2; What comes out? Study polymorphisms as well. They really expect 95% of correct answers.

Fourth interview is HR. Not hard, just a classical HR round.

Last interview is with the manager. Behavioral questions, how you work in teams...

Most of them are on Glassdoor.

Whether you are interviewing with Cambridge, Natick, or Bangalore, the questions are always the same as they just follow a procedure.

Please spend the time to gather all Glassdoor questions.

They may sometimes seem stupid, but that's really what they're going to ask!
