There are multiple good reasons though, and it’s a good question.
First, whoever answers it well is going to have a leg up, whether it’s asked or not. Would you prefer secret questions you just have to know or would you prefer they just ask you explicitly?
Second, if you’re so jaded that you can’t come up with a reason, however minor, you’re probably more trouble than you’re worth. Negative morale is contagious.
I’ve always enjoyed fashion, and I like being able to work with people to find what they like.
Assuming hotel for “night”. People tend to be more honest and interesting at night, sometimes for the worse, but sometimes for the better. I don’t mind being personable in that way, and I appreciate quiet time to keep things organized. It can be a lot like solving a jigsaw puzzle, except you’re actually getting something done.
It’s not that hard. It doesn’t have to be your goal in life. They understand you’re there primarily for money. But it certainly helps if there are things you like doing at least a little. Prompted or not, someone who talks about those reasons is going to do better in the interview than someone who doesn’t. It’s easier to tell them if they explicitly ask you. And if you can’t find a reason, I guess you better hope there aren’t too many applicants for that shitty job.
