I was an intern in OBSS so I didn't deal with a lot of interview process. Most of junior say they attend more than 4 interview. I did my last interview with Vice President via Skype.

interview holds on their office at anatolian side of istanbul. there was interview groups. They did not care about people's much. They are just doing this interview for show. Actually it does not very elective. Their company was not big as other but they gives to much care about too much.
