Very interesting questions - from the very basics to medium to complex. Even the CEO asked bunch of technical questions - most of them were related to data structures and algorithms. I couldn't answer some of them but I was surprised to see the CEO took the time from his busy schedule and explained each one of the algorithms and why he asked such questions. Since they are looking for experts to build a center of excellence, they are looking for the best. I hope I will get an offer.
