First question was on palindromic strings of 0s and 1s that I spent too much time on, The second question was "simple" sliding window question on memory allocation. It's funny that I have been in long meetings to discuss this kind of logic, but somehow there was an expectation that I would code this on the spot. Yeah, I failed the tech hazing here. The system design questions were really well-made. I honestly had a lot of fun answering those. Lots of things about availability, architecture, and databases.
