First round was a hackerrank test following which the first technical round was scheduled. I hate to be writing about this but someone should. It was by far the worst interview I have ever attended. I will be giving the same feedback to the HR. The interviewer was rude, had a ton of negative attitude, he was insulting and very harsh. He was very unprofessional and made me feel extremely uncomfortable throughout the interview. I ended up telling him that he was rude to which his response was "this is my way of taking interviews", "I am supposed to say harsh things to test you", "if you can't survive the interview, how will you survive the workplace". He made a lot of personal attacks and was unbelievably sarcastic throughout. In the end, I apologised to him for my behaviour while he assumed that I overreacted due to a personal problem and not because of his poor interviewing skills. Worst interview experience ever. The interviewer's behaviour says a lot about the workplace. Never again, Acko. I DO NOT WANT YOUR OFFER.
