Infinitive interview questions

I had a recruiter call, then a virtual technical, then an onsite technical and behavioral. I was given an offer, which I accepted and they told me it was contingent on the project accepting me as a software engineer. That was almost a year ago and even after following up with the recruiter I still haven't heard anything and have not started working. Stay away from this company, they are completely unprofessional and a waste of time.

Typical process. 1st round is the hiring manager's call. They talked about the company's culture and asked me questions like "Tell me about your self" "Why are you looking for new opportunity" . 2nd and 3rd rounds were mixed. They both asked some behavioral and technical questions. Every person I met each round was very nice!
