Epicor Software Software Developer interview questions

I had attend interview in epicor, I cleared all three rounds of interviews. Even person told you have done three rounds (during managerial round) and just wait. I was waiting and HR came and said congratulations mohan you have cleared all three rounds and next week our Director is coming from USA so I want to introduce you with them, it will be hardly 1 hours that's it. I was waiting but with in a week I didn't get any response no call, no email, later on after 10 days I get a response via email. Sorry mohan you are not qualified. I don't know what's wrong there anyway this was my bad experience. So I will choose negative only

The first round was a technical round where they asked a lot of questions about java and algorithms. Also i was asked about my final year project. The second round was a puzzle round where i was asked 2 puzzles . The third round was the manager round where he explained in detail about the role i had applied for and asked me if i have any questions regrading the same . The final round was the HR round .
