Continental Software Engineer interview questions

Contacted by HR via phone. There are two rounds of interview: (1) interview by team members (2) HR interview. Asked about your prior experience in embedded system, especially software development life cycle (V-model). Asked to draw a state diagram and realize it in C (tip: use switch statement, can google online). Asked to solve a couple of C problems (stack allocation, create linked list, size of a C structure, choice of return type (use double or long long) in function to avoid overflow etc) on the whiteboard.

Three interviews. First one by phone with HR representative. Normal questions about the CV and general skills. Second interview with group leaders of a business unit. Deeper technical questions about the projects and jobs in which I have been in and the relation between this and the job that I will be doing, in my case was in embedded Software. Third interview with the team of one of the group leaders, with whom I had the interview before, as well as the manager of the business unit. Mainly same questions as second interview.
