Valeyo interview questions

I was contacted by an agency regarding a PM position. After an initial call with the recruiter....there was an interview with a Valeyo employee. The interview went extremely well and I was told that I would be having a second interview with another Valeyo staff member. That never actually happened as the second person went ahead and hired someone else without actually following through on the second interview that the company stated they wanted to have with me. By far the most unprofessional experience I've ever had in my career when interviewing for a job. Clearly there are internal politics at play here....this place is best avoided as they just waste your time and play games with candidates.
