Fidelity Investments Full Stack - UI + Java Role interview questions

I had over all 5 rounds. First 3 were technical rounds. Next was manger then HR round. All the interviewees were nice except the HR. He was very impolite, and after hearing I have another competitive offer was not keen on discussing. He told me I had another round with US people in the subsequent week. I had gone through the consultants Allegis who confirmed me I was through to next round. But never got a call back from the Company or consultant despite many reminders.
