7 interviewers, 3 asked some technical stuffs (C/C++ programming). Although I didn't answer 100% correct (I would say about 90% correct), but they told me that I understood the concepts well. One of the best interviews I did, but somehow didn't get an offer. Curious what they base their decision on. Side note, somehow almost all of the interviewers kept emphasizing how nice people at SISA are, and I didn't even ask directly on that topic. I found that a little interesting.
