Cintas Sales interview questions

On campus interview followed by a several hour multi-round interview in the office with other upcoming college grads. I had applied for the internship position and got a brief overview for the intern position but was told by the interviewer that he didn't know specifics. Got scheduled for a multi round interview the following week and upon arrival realized I was the only candidate applying for the internship position as opposed to the sales management trainee graduate position. I privately expressed my concerns about being at the correct interview and was assured that I should be there because "the sales management position is what you will work towards as a sales intern." I did the entire interview and was called the following week to let me know I did not get the sales management trainee position. I told the woman who called that I had actually applied for the sales intern position, and she expressed that the position was the same. I then received a call a month later asking for me an interview for the sales intern position, and I declined.
