National Stock Exchange Information Technology interview questions

easy as i was a fresher. 3 rounds, Aptitude. then next will be F2F Interview where basic interview question they ask. GD is for cut down multiple candidates as per comm skills. Technical interview final and then HR round.

There was first round with project manager to understand background. Second round was a technical round Third round was with Talent Acquisition Head After that again there was 4th round with reporting Manager for in depth discussion. He told everything is good to go and there might be one final round with CEO if CEO wants to take.. I was given rough offer letter and told to approve to get final offer letter. Now the problem starts. CEO doesn't approve the offer letter and I was communicated that HR Head wants to have one more round of interview. I cleared that round and recruiter told me that they will issue offer letter as soon as CEO approves. Now again the recruiter comes back they want to have one more round of technical to check cross business unit fit. I was told it is just routine check I have been selected. In this next technical round which lasted 30 mins, I speak for 15 mins about my past work experience and next 15 mins I was asked couple of questions on the technology which I have not worked on and then next recruiter says that I am rejected. They wasted my 3 weeks keeping me on hold and just rejected because of no reason.. Worst experience in my whole career
