Terrible Interviewer. 5 minutes late. Is distracted, asks me to wait for couple more minutes. Asked me to turn on the camera but keeps his off. Asks HashMap working but was not able to follow up with my answer. After explaining multiple times says he was expecting 'this' answer and repeated whatever I was saying for the last 2 minutes. He was more interested in knowing obscure internals of programming language instead of judging development skills. Total waste of time. For the first time, I, interviewee wrapped up the interview in 30 minutes.
