Meta Software Developer interview questions

The interview process was straightforward: Phone screening -> coding interview -> 4 interviews (two coding, one behavioral, one system design interview) The coding interviews were decent and not too difficult. They used a couple of tree and graph problems. They asked a lot about time and space complexity of the code I designed. Behavioral was about my past experience and how I would act in a given situation. The system design interview was a bit more difficult. I studied for this one as it was my first time doing it, but they threw me a curve ball and asked me to design a component I was not aware of from a technical standpoint.
