Optra Group of Companies interview questions

There were 2 technical rounds. First one went really well and the interviewers also seemed happy. but the second round was a disaster. The Project Manager was very rude and it looked like she had already decided not to hire me and was biased. Asked me irrelevant questions (nothing to do with my work experience or their project for which they were hiring).

First round was a basic aptitude and a technical written test, after that there were two technical rounds the second being with a project manager. The questions were based on my college project and language basics.
