General Motors (GM) Sr. Software Engineer interview questions

I applied for the position in the beginning of the December 2015, the process took about 5 months. First I got call from TA team (Recruiter) in January 2016, she asked me few questions and other educational and experienced related informative questions; then I got another call for scheduling an interview with Hiring Manager in the beginning of February 2016 for about an hour; after that I got another (Final) video conferencing interview scheduled in the end of the month February 2016 for about 2 hours with Hiring manager and the other technical departmental person (1 hour each). I got interview response after a week and then rest of the documentary process started. Interview was easy. Hiring manager and the departmental person who was taking the interview were nice and polite, actually I talked with bunch of different people in GM from the starting of interview to the end of the process everybody were nice and polite. In interview they asks STARLA type of questions in the interview and of course few technical questions. Overall good experience from starting to End, but very slow process.
