TMA interview questions

The interview process started well. First I spoke to the recruiter. Followed by two additional interviews. They both went well. I was given the impression that I had the role. It was near the Christmas holiday and I was told they would make a final decision after the new year. After many follow-ups throughout January, by mid-February, I was told by the recruiter that they hired an internal candidate. Very frustrating and unprofessional.
