Custodians, also sometimes called janitors, are responsible for maintaining public or private spaces such as schools or office buildings. Custodians clean these spaces, but they also maintain equipment, alone or on teams. Some custodians work primarily when other employees are no longer in the building, but others may frequently interact with employees and the public.

When preparing to be interviewed for a custodian position, you will want to do everything you can to show the interviewer your attention to detail and custodial knowledge. Expect questions about how you have cared for equipment, how you clean, and how you have solved problems in your previous experience. 

Review this list of frequently asked interview questions for custodians and practice your answers in advance.
