I was recommended by a friend currently working there. I got a phone call and they provided a link to solve a code problem. The phone call was disconnected several times during the interview. The interviewer was talking to me as if it didn't matter what I do my answer was always going to be incorrect. I provided an answer to the question that actually works but he wanted a better solution. My answer was O(n) he wanted a O(log n). I believe there's no actual answer to the question that can be O(log n) (the worst case scenario would still be O(n)). That was the whole interview, one single coding problem. In the beginning he asked about my past jobs but I could tell that he wasn't interested in that. He kept sighing as if he just wanted me to finish already with that part of the interview. He kept giving me hints on how to answer the question according to him, he wasn't allowing me to come up with my own solution. After the interview I was able to answer the question, but by no means is the solution he was expecting, so I'm going to assume it wouln't have been good enough for him. I never got a call or email back after that interview. Not even from HR.
