FIS interview questions

Met with a recruiter and a department supervisor. Talked about experience and the role. What to expect. Benefits. Shifts. Fairly simple process. Walked out with a job offer. I can't think of anything else to say to make the 50 word minimum. Blah blah blah blah

The interview process was quite smooth they only ask the basic question on testing and mainly emphasized on what i had done in my previous projects that was the 1st & 2nd.. 3rd round is the client interview in which they asked the same thing's as asked earlier it was a telephonic round from U.S.I think i answered all the question & i was very confident about my selection.But next day i got feedback i was not able to make it.I think just made one mistake about 1 unix question which was about grep command syntax i used double quote but I should use single quote with searching string.I really feel very bad for this mistake.I think may be that was the reason .Anyhow Fis Hr & Technical recruitment team all very professional.I really appreciated for their effort.They all are doing great job.I hope i will get an opportunity again & next time i will make it. & i will make long term relationship with them..Once again thanks for giving me this interview opportunity for this prestigious organization
