I had an ETL Intern at my store for a 10 week period, you basically go around and learn how to doe very single thing in the entire store. You learn the floor, front lane experience, backroom, and other things. You will be referred to as a leader and will give out orders/directions in the latter of the 10 weeks. If you do get to intern, you will be taken under the wing of an ETL at a store who will show you everything, along will everyone else helping out.
