Intapp Implementation Consultant interview questions

I was contacted by a recruiter regarding job opportunities. The interview process was lengthy. 6 total interviews. The first red flag was when the recruiter sent me another candidate's resume with an interview confirmation. I still continued through the interview process. The last interview was with the senior director/VP. I was told at the end of the interview, I would be receiving an offer. Even the hiring manager called a few days later to reconfirm my interest in the role. Fast forward to the next week and I get a call from the recruiter stating they went with another candidate. Completely dishonest on the company's part. Definitely wouldn't consider this company in the future due to the lack ethical standards.
