Saint-Gobain interview questions

I went through 5 rounds of interview. 1st round was an interactive online video answering rendering round, which was very new concept to me. 2nd round was a telephonic interview with my prospective supervisor. 3rd round was an in-person interview with business development manager (colleague). 4th round was in person interview with the supervisor himself. The 5th round was a telephonic interview with the supervisor's supervisor!
