Epicor Software Sr Software Engineer interview questions

They called for interview and sent a mail to fill up the form. I have sent the form with details. After that they called for interview at office 1. Technical discussion with manager 2. Technical Discussion with Senior manager 3. General Discussion with VP 4. HR Discussion

one tech interview ,one Director round and one VP round. One round of little long as compared to other 2. Only disappointment was after clearing all rounds HR didnt call me back > I tried calling him but he didnt pick my call . He was unprofessional guy who doenst know ppl can call them not only to ask for offer letter but to get the honest feedback to if anything stopping them to release offer letter .Grow up
