AMD interview questions

Recruiter reached me out online. Very general HR related questions. Then hiring manager set up 2 different rounds of technical interview sessions with his 2 staff engineers. Each interview was scheduled for 1 hour but each time it went close to 2 hours. Recruiter said 2 of these interviews went very well that the hiring manager wants to screen more. I was told I would be reached out with a week but I did not hear back from them ever. Finally when I reached back to the recruiter I was told that they already found a candidate. Although I was told that there will be more screening but in the end it did not happen. Very poor professionalism.
