Which department to go to depends mainly on your major and interest. Interview once or twice. Interview several times. Take it easy. It's just a retail store. This is nothing, let alone a part-time job. After the first interview, you won't lose face unless it's far from the requirements or something new.
Some department managers will also ask professional questions, and all kinds of questions are actually a question to test whether the answers you gave before are true. If you are asked to find something, don't worry, they are analyzing whether there is something wrong with their monitor. Of course, you can't find it for a long time. Maybe your logic is a little confused or nervous, so relax.
I can't forget the working atmosphere inside, which can make people ignore the treatment and hard work. A positive place is a good place to exercise without leaving school.
Don't forget to give yourself a nice English name. Ha ha.
