I've done a few resets recently. They take about an hour each. They are pretty easy, you follow the planogram they give you. Most of the time other resets are taking place at the same time so there are many people there. In some cases you have to relocate a shelf, but the other resetters who are there will help you lift the shelf out and move it, rather then take out all the Red Bulls and move it yourself.
The one draw back is that when you get them, most times they will assign you a second store right after. You have to wait until the Coke team is done with their resets before you can go to the other store. The Coke resets take up to three hours so you wait around. One team lead gave me the planogram for the next store so I could go do it, but another one did not and i waited a while. I like them, and hope to do more when come out again.
