What do you like least about being a janitor?

Most of us have some piece of our job that we do not enjoy as much as the other pieces of our job. The key is to share this without complaining about it. When asked this question, laugh, and humbly tell the interviewer what you like least. Reassure the interviewer that you really like being a janitor, and you will happily do this part of the job because it comes with the role.
