Monster Lead Group interview questions

I applied online and had an interview with the recruiter pretty quickly followed by two more interviews after that. The second interview was with the manager of the position and another department manager. The third interview included leadership. I was told throughout the process that I was the leading candidate and I was asked to provide samples of work. I had to reach out after the interviews to find out if I was going to be offered the job, and I was told they went with someone else. I asked for feedback as to why I wasn't selected and never received an answer.
