Capital One IS Audit - Principal Auditor interview questions

I was contacted by an internal recruiter to apply for an existing position in Plano, TX (that of IS Principal Auditor, specifically). Between that initial conversation and providing my resume, the position was filled out of the Richmond, VA office. Odd, but okay. The recruiter expressed interest in me still, continuing the recruitment process by having a phone interview with someone in the same department I would be working. It went well and I was invited in for one of their "Power Day" programs, consisting of 4 interviews - 2 job fit and 2 behavioral. During one of the behavioral ones, the interviewer mentioned my potential responsibilities as an IS Manager - Internal Audit. (This is a higher level than Principal Auditor, requiring more experience but also offering better pay.) Confused, I asked for clarification in my thank you e-mail later that day and was told I was now being considered for the Manager level position. Fast forward 3 days later when I was contacted by the recruiter. Despite having the job qualifications, I was told that there was not a business case for the Manager position and thus they could not extend an offer. So, to summarize: 1) contacted to apply for existing position; 2) position filled in another location; 3) asked in for an interview; 4) position switched on me without notice; 5) declined for job due to business need not existing (again, for new position they changed it to). Very unethical and deceptive hiring practices. Beware!
