CIBC Customer Service Representative (CSR) interview questions

I was called to set up a phone interview and then the next day I was called by my local branch to set up another interview but my call was never returned from the branch so I went through with my phone interview. It started out great. I was asked things like why did I apply for the job, what I thought the job duties were and all the kind of stuff. At the end of the interview I asked what would happen next and she told me I should know the position was actually filled already and there were no other openings in my area but she encouraged me to keep looking. This really upset me. I had just wasted 15-20 minutes of my time. I feel like telling me at the end of the interview was very unprofessional when I could have been told in the beginning and had the choice of going through with the interview or not. This left a very bitter taste in my mouth about CIBC a company I would have loved to work for up until this point.
