For the most part they were basic probability and coding. After reading other reviews, I seem to think they're recycling the interview problems: - Basic high-school probability and number puzzles. - The CTO wanted to implement a linked list, and reverse it (extra credit for in place reversal in a single pass). - One of the engineers tried to prove he was smarter than you but providing very sparse details on his problems. It was also a bit annoying when he didn't acknowledge any correct answers and simply wanted to move on to the next problem.
