I have Got the interview call through a recruiter and scheduled interview for the next day. Technical round was scheduled. They didn't inform how many rounds will be there. Awaiting for the result of first round

I gave 2 rounds, both were technical. My 2nd round had gone well, which I gave on 12th February. I kept following up with the HRs but got no response on the feedback, and I receive the email today, i.e. after a month saying I was not selected. If the feedback was negative, I should have been informed about this sooner rather than being kept in the dark.
