Everything in that interview was negative, starting with HR to the interviewer. I got a call from HR that interview will be on coming Saturday in the first half but nothing was finalised. I received an invitation directly when I tried to reach HR if I can reschedule it to one hour prior or later she started screaming. I accepted the invitation and rescheduled other things to find another horrible interviewer. Interviewer asked me to turn on my camera with his closed then he was sounding as if he is having a tobacco and with absolute dissrepect he was asking me questions as if I am forcing him to interview me. He asked me to solve one coding problem when I started to explain him the approach he refused and told me to directly write the code with O(n) time complexity. I wrote the code with unoptimized way with O(n) time complexity. Then he told me it is not in O(n) time complexity as you have used 2 for loops(not nested) so it is O(N)+O(N) = O(2N). I gave him better solution. then he started asking me questions and I made a mistake for 2 questions and he started humiliating me by saying this is what you have ? this is what I ll get if I ask this question to a 1 year experienced person.
