I have had the worst Interview experiences in my entire 9-year career. I had a technical interview with the hiring manager. He was sitting in a dark room and looking at the camera sideways. I could only see his face from the screen's backlit light. No introduction, and I was given a Graph problem, and I explained the approach and wrote the solution, and it passed the default case. I knew it missed an edge case, but the interviewer is smirking in the background and saying, "Oh, you got lucky, you used priority queue, otherwise it would fail, and this code has a flaw, it will fail", "bad logic". While I was updating my solution for any code change, he was making discouraging noises that were distracting. And saying "this is a redundant line", "this is stupid". With 20 mins to solve, I was debating whether to continue the interview or not, and intentionally chose not to solve and asked to end the interview. Reason: If I get the job, I wouldn't want to work with him as a manager. I didn't expect this from Goldman Sachs. Please treat your interviewees as humans, if not equals. And please train your staff on how to conduct interviews.
