First - phone interview Second - Skype Interview The first interview went really well. The interviewer was super nice and very patient. We went through one question together and I asked him a lot of questions at the end. I ended the interview a little early because he said he had nothing else left to ask. The second interview was awful. The interviewer was still nice but the interview itself was in my opinion very bad. He asked me a question on something I was not familiar with at all. He had to teach me the concept in ~20-25 min of the interview and had me do a problem on that topic (it was networks related concept which I wasn't familiar with). The interview took way longer than planned (60 min) because he had to explain the concept and the example input/output to me since I was unfamiliar with the topic. I didn't think the question was a good evaluation of my skill. I would assume that they are testing my algorithm and basic cs fundamental knowledge. If the interviewer had to explain a new concept to me and had me do a problem on it, it's not a good evaluation of my algorithm and cs skill. It was more of testing how good I am at grasping new knowledge under time pressure and interview pressure. I didn't feel like it was a good representation of my technical skill at all. I've had many interviews so far and this is by far the worst one in my opinion. I got rejected two days later and the reason was (of course) my technical skill wasn't good enough. I feel like the interview was poorly conducted and did not allow me to show my coding skill.
