Definity interview questions

I had a phone interview with the recruiter and discussed about moving to the next round for the role of "Head of UX." A few days later, an interview was set up for "UX Manager" with the hiring manger. I asked the recruiter if it's a mistake, but got replied that "we would like to interview you for both roles - we have 2 roles currently open." There was no previous communication regarding the "UX Manager" role until I asked. As UX manager role is a level down from my current role, I expressed to her that I would only be interested in the Head role. 30 minutes later, she replied that they already filled the Head role and asked if I would like to cancel the interview - and of course, I said cancel it. This recruiter is extremely unprofessional and need to improve her communication skills. Candidates should not be moved into other roles without communicated. It was a bad experience for me and I feel I was tricked into the process for a role I didn't apply for. It was a waste of my time.
