My interview went well until I said these magic words...."I am looking to work 3-11 as I am taking courses to get into the RN program." Well, I got, "We have a strict orientation process and if you go to classes then you can't work here".
As someone who has conducted more than my share of interviews, I can honestly tell you that the interview is not the place to express your personal wants or needs. Employers are looking for people who are interested in meeting their
needs. If you start laying down conditions from the beginning, you are (a) assuming that they are going to offer you a job, and (b) telling them that they need to meet your needs first. If I am interviewing, in most cases I am looking to fill a specific position that has a specific schedule. I am very sorry if it isn't your preferred shift or days off, but that is where we have a vacancy. It may seem cold on the surface, but if I granted every employee everything they wanted, we would have no night shift and the facility would be shut down on weekends and holidays. I must staff a 24-7 operation.
When you begin imposing restrictions on a prospective employer during the interview, you create the perception that what you want is more important to you than the job you are interviewing for. It is best to go through the interview without mentioning your personal wants, then decline the job if an offer is made and you decide that you can't live with the conditions of employment.
As an alternative, ask the employer what their needs are (shift, days off, etc.). Don't react to the answer, even if you find it totally distasteful. If they ask you what your impression is, simply say "I would consider it." If they offer the position and you decline, explain your reasons at that time. You stand a much better chance of getting a callback for a position that more closely meets your needs because you considered theirs. A lot of getting hired is the impression you make. In essence, you are selling youself and your services, and the more attractive you can make yourself to an employer, the better your chances of success.
We interviewed RNs a couple of months ago, and one applicant told us what his availability was - including shift and days off. He immediately went into the discard pile. That told us that he is inflexible, what we needed made no difference to him, and in all likelihood he was working a second full time job that we weren't supposed to interfere with.
