Absolutely the worst interview I've had this term. The interviewer was very unprofessional. He even laid back into his chair and turned away during the interview. He drew question was given on a online drawing tool with no text, which I cannot see unless he share his screen. The problem is, he is also checking my code, which made it incredibly difficult for me to see the question. The coding editor we used was also really sub-par (think no auto-spacing, no auto-completion). I have no idea why he didn't use coder pad. In addition, the interviewer tried to explaining the question but was very poor at it, and I had to ask for many clarifications. He was talking for a long time about the question with no useful information. I got the answer at the end, but we ran out of time so I just explained how I would solve it. I didn't like the question either, it's basically a brain-teaser type question. P.S. I genuinely doubt anyone who interviewed with him would get an offer.
