GEP Senior Asp.net Developer interview questions

The process was very long. Took an entire day. Started with an online test. After which there were 2 technical rounds. Cleared the first one. Took almost for an hour. Then made me wait for another hour for second technical round. That was for about half n hour. Both went good. Final was managerial round. I was told that would be later and asked to leave. And later after two days got a mail saying I dint fit the role. Without giving any reasons. And in the mail was mentioned to call incase of any query. But no ones receiving any calls.
