Verticalmove interview question

Client repeatedly changed the position during the interview process and recruiters even had mentioned that they had changed it before with previous candidates, that the position had changed. This same "recruiter" then called me a jerk when I asked about it, complained that I gave attitude to his recruiting assistant who was just months prior a snowboarding instructor. Yet I was still being pursued as a candidate...until I withdrew because the "recruiter" called me a jerk because I asked about the change and when they lied and tried to badger me into submission by claiming I misunderstood. Questionable ethics and critical thinking ability with these people in my opinion. That's when the brow beating by this "recruiter" began with name calling and forcefully claiming that I misunderstood and the client is not changing anything. Kind of reminds me of "Business Careers", the now defunct recruiting agency. Just my opinion.
