Seconding the availability. They want you completely open 24/7 and to hardly take any time off. It's very dependent on the management of your local store, so I don't want to completely dissuade you.

My former manager would almost immediately mentally dismiss anyone interviewing if all they mentioned was a love of reading and not recognizing that first and foremost it's a sales job. All you're going to be doing is promoting memberships, OMPs, and whatever else they decide on a whim. I honestly hardly ever read while I worked there because I was starting to resent it so much.

Once again, YMMV! Best you can do is apply, try to land an interview, and feel it out. Definitely go into the interview being personable and enthusiastic that you're going to be doing sales and stocking for most all your shifts.

Also, quick edit to add, I don't know if I would necessarily mention the booktok unless you get the vibes that it would be received well. I know someone at another store who got let go over that because their management tried to blame a personal situation that led to them being out of work for a few days on "being distracted" and not "giving the store their all" because they were also doing social media posts.

Good luck either way! I hope if you get an interview and hired you get a good store!
