Capgemini Sr. Software Engineer interview questions

The interview was scheduled by a recruitment agency and conducted in Bellandur 6B building. When I entered the place I noticed it was a recruitment drive going on with almost 200-300 candidates like me for different profiles. This is a sign where these kinds of tech giants hire a lot of developers for some project and layoff the same way when they are done. I was interviewed by a dumb person there. This idiot posted questions from every part of my skill set but was so dumb. For a 5+ year developer, he was posting questions on OOPS concept and the irritating part is, he never gave a pause for me to answer! Such an attitude he has got! He posts a question and he himself says its okay you don't know that. WTF?! A couple of days before, I interviewed a candidate from Capgemini with 6+ years of experience who didn't know the difference between WCF and WebAPI! I doubt if these people are capable of doing anything. Please don't waste your time with these kinds of stupid cowshed. I would suggest any passionate developer to join a proper organization where he can have good career growth.
