had oa, recruiter chat, technical screen. I've interviewed at multiple big tech companies such as google, doordash, amazon, etc and have received multiple offers, and so I can say that this screen was with the worst interviewer I've ever had. I was 30 seconds late and when I joined he signs and says "finally". He asks me to introduce myself but does not introduce himself or shows any engagement at all. When we code he repeatedly tells me I am in correct direction but does not give me any reason why my code is wrong but doesn't let me move on. I try a solution which he says is wrong then I try something else but he says the correct way is the solution I tried previously. He then tells me I have a lot to learn. I did not finish one part so I asked if I could walk through what I would do and he laughs and says if I couldn't do the first part this is too hard. It was overall a negative and unprofessional experience. I have preformed badly on interviewers before but I have never felt disrespected like that.
