FIS interview questions

The interview process went for almost 2 months and I cleared 5 round of interviews and then had a final round with HR that went for more than an hour after which HR offered me salary and also told me about all the benefits that I will be getting . Also, she informed that I will get the offer letter shortly or by next day. Guess what ? That day never came. I followed up for around 15 days and everytime she said its in process and then called me and said they can't gave offer letter and made some stupid excuse like project on hold etc etc. She came back saying she will arrange interview with another team but I declined this time.

There were total 4 rounds including aptitude(mcq test), programming, Group discussion , Technical Managerial interview. After that they conducted one interview with TPO head. Overall process took near about 2-3 weeks. They declared results after 2-3 days after final interview.
