Worst kind of interview ever. The interviewer appears to be a fresher or lesser experience where he searches for the questions from geeksforgeeks sitting in the interview panel and expecting the 1st solution that comes up even if better and optimised solution is given. He himself doesn't understand what the problem is when I asked him to explain it. Really embarrassing situation. If not interested in hiring, don't schedule the interview and make the candidate come down. This would be better than asking a lesser technical guy to sit for the interview panel just to reject the candidate.
HR took 2 weeks to schedule the second round after the first round and that too after me asking whether I cleared the first round or not. Absolutely non existing communication from the HR. In the second round interviewer asks me whether this is the first round or not. He doesn’t even know whether its the first or second round. Clearly indicates their seriousness while taking interviews. Don’t waste your time interviewing here.
