Healthcare Services Group Manager Trainee interview questions

I applied online for the position but the person I spoke to only said he got my resume and was calling to set up an interview for the next day. I asked him to tell me more about the position and he seemed hesitant to do so. I kept probing and eventually he told me it was a management trainee position for about 90 days and then I would be placed in an Account Manager role. He said I would receive information via email as to the time and place and I should respond back to confirm. I asked him to send me the web link and he said he could do that. After the call I went to the website and it had the usual testimonials from employees talking about the role of the account manager and how wonderful the company is. The next day I arrived at the interview and was met by the individual I had spoken to on the phone and a person introduced as the Regional manager. He then went on to tell me that everyone starts at the bottom and my first 90 days would be spent learning how to clean toilets, change and make beds, do laundry, and do other general cleaning because I would not be able to manage the staff without knowing how to do the job myself. REALLY???????? He then proceeded to talk about the wonderful career path I would have once I subjected myself to 90 days of their slave labor. I have managed people in various roles and companies for over 20 years. I took this interview because I saw this as an opportunity to move into a new field but I don't need to clean a facility to know how to manage a team that does that. I should have been told this piece of the puzzle on the initial phone contact and it would have saved all of us some precious time. I thanked both of the managers and left.
