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.
