FIS Senior Software Engineer interview questions

Three rounds of interview + HR round. First round telephonic with local team leader and then two technical rounds with onsite manager/project manager. Interview was for 30-45min average and my interview was with onsite managers and everything was scenario based questions. So candidates who have real project experience can answer them.

I applied through consultancy agency, appered for F2F interview there were 20 odd candidates. Some quality in depth questions on C# language features like delegates, events, CLR, GC, memory management, oops, asked to write scenario based programs, object oriented design patterns, mvc, IoC, Dependency injection, WCF, SOA etc. I asked almost all the questions correctly and confidently, interviewer even ran out of questions and was impressed. It was a good 1 hour interview. Interviwer told me that he is done and he will provide the feedback to HR and HR will get in touch with for further process. Till now I am waiting for HR feedback. When I followed up with consultancy guys then I came to know about my rejection, I was shocked to see such a non professionalism by a reputed firm. Despite of such an outstanding performance they rejected me. I don't know why HR didn't even bother to provide feedback. Its ridiculuos. Anyway, later on I got a better offer from another reputed software product firm with much better pay and lucrative career opportumity than Sungard/FIS. Thanks for your rejection without which I may not have appeared for other interviews and possibly wouldn't have landed up my dream job.
