Catholic Health System CNA interview questions

A day or two after submitting my application online I was called to set up an in person interview. When I arrived for my interview I waited an hour because the person interviewing me had a meeting. They decided to just have another person do my interview which I thought was fine but she had no idea what position I was even interviewing for. So, it wasn't much of an interview, I was just asked why I wanted to work there and if I needed any days off. I received a call back a couple of days later and was offered a position. I had applied for the 1st shift and said I could not work the other shifts, so I thought that is what I was being hired for, it was not. I was also unable to find out if I was hired for a full-time position until I went into the facility for my first day.
