FIS interview questions

Asked interview questions were pretty easy in initial 2 rounds. Third round was with the architect of a project and didn't go so well for me . In this round,at the end interviewer asked me to write code and send in email.So,as discussed I did the same but never heard back from HR. Just want them to know it is fine to tell an interviewee that he/she didn't make it through. Don't let them waste their energy in sending out email to you and try to follow up!!
