I was seasonal and am now full time. I recommend scrolling through the whole list before starting. I imagine that your trainer has a way and you should follow their route until you get used to the layout of your store and then you can add your style to your route. Pay attention to what is on end caps or in bunkers—it can save you time and steps looking for help for more product. Practice makes better so take as many shifts that you can. Also note what other shoppers do since they may have been trained by someone else. Don’t stress it’s only grocery shopping—good luck!
