My first interview! Help! Questions? What do I wear?!

So I’ve applied for a sales associate position. I have no clue what kinds of questions they will ask, how many, etc.

Can u guys give so examples of questions or good answers from ur experience as either an interviewer or the one being interviewed? Also what should I wear? Idk if shorts r a good idea? Jeans r probs a no??

Hellppppp

Edit: I’ve been looking common questions up and practicing what I’m going to say an stuff so hopefully that’s enough haha.

The interview is Friday so tomorrow I’m gonna have to go out and buy something (u may have saw my other post that my house has fleas so all my clothes aren’t usable rn especially as we just bombed the house. But I think I’ll post a picture on here of what I end up getting to see if it’s ok or not. And thanks for all the help btw!
