I had 3 technical rounds of interview and 1 introduction round with manager to under candidate profile. Between introduction and technical rounds, 1 week of gap. Technical interview was easy it covered android and java mostly. They were checking basic but in depth knowledge. After 3 rounds which I was confident that are going really well. I get a feedback from HR that my profile does not match the requirement. This has left me confusing because if that was the case after the introduction round technical rounds wouldnt have been scheduled. And in atleast 1 of the technical interview I would have atleast 1 question related to those specific requirement where my profile din't matched but it did not.
