It was quite simple. I filled out a paper available at the Front Desk and was called 2 days later for an interview the next day. Spoke with the immediate supervisor and the senior manager of the library, for about 10 minutes. Questions were straightforward and revolved around what my academic schedule is like/how reliable I am/if I've ever worked in a library before.

Had to fill out an application form from the library. Immediate supervisor set up a time to meet, then went over my application form with me. Agreed to hire me and started setting up schedule on the spot. Pretty simple.
