Zulily Senior Software Engineer interview questions

Overall it was 4 interviews; 2 coding 2 sys des 1 casual lunch. I met with 2 senior engineers, a principal engineer, the hiring manager, and another manager for lunch. I can't even be bothered with pleasantries for this one. The interview with the principal was really dumb because he would rant and state that he is trying to be politically correct and non-offensive about conversation that wasn't offensive while being offensive in the things he was actually being crappy about. For some reason even though it was a cloud company interviewing a cloud engineer for a cloud position, he asked me an operating systems question; design a process scheduler on a single host with 4 CPUs. Why am I being asked a question on a topic I've studied way back in college? At first he wanted code and then clarified that he wanted design, like how do you mix those two up? We also had a terrible technical discussion: I was also asked to hyper deep dive into the five disadvantages of my chosen programming language and to give detailed examples. Like are you kidding me I can't even think of five disadvantages to driving much less a programming language.
