They just asked for availability and if incase of necessary knowledge in handling money to be place as a stand in cashier, it's most likely that they need people to work the weekends or with open availability as is easier to place in spots where needed, my interview was over the phone they gave you a time they would call and if they don't call allow for 15 minutes before calling directly to the store.

Straightforward questions about availability and hypothetical situations in the workplace. This interview was simple and is mandatory for everyone who applies online. It is called a "group interview" on their site though you may only be interviewed individually at times.
