This’s the worst interview experience I had. After 1 month, the hr gave me feedback and told me not move forward. The final interview round is really sucks. The interview seemly didn’t listen to me and refuse to understand my solution. He just said it was wrong but it’s correct. So ok, I used another way and he said it’s really good. I finished two questions in 30 hour with most efficient algorithm and he agreed with it. Then he let me end 15 min early. In the end, I was just damn rejected after 1 month. How worst is it? I will never interview with LinkedIn if they let such hr and interviewer keep doing such thing.
