The interview was scheduled by the recruiter. The interview schedule mail had all the information in details mentioning that the interview will be on a hackerrank platform specially customised for Oracle. Don't get your hopes high seeing the mail. Their interviewers are not at all professional or have any experience in taking interviews. Not judging anyone by their prowess in English but the interviewer was struggling to communicate properly. First had a brief introduction, then he gave me an option to go for either DS Algo question or implement something in JS. I opted for Implementation question and he asked me to implement TIC TAC TOE in js in 45 min. I said i'm not sure if I can complete this in an hour. So he was ok to go with DS Algo question. I solved the 1st question with a solution that was different from his leetcode solution that he was referring. He tried his best to break the code but to his disbelief he couldn't. Then he gave another question which was rather simple. Again I implemented in one way but the 'Crazy' interviewer wanted the exact solution that he was seeing in his leetcode screen, even though my solution was better . By this time I had it had an argument with him and left the interview saying I'm no more interested in such company with such toxic people. Such a ridiculous interviewer.
