Delivery Station Liaison

Hi Amazonians!

I start my L3 DSL position in 5 weeks. I have a few questions:

1. What color vests do DSLs wear?
2. Do DSL associates work with the rest of the station? Or do they typically stay at their desk?
3. Are there windows in a DS or is it dark and depressing?
4. Are there usually more than one DSL associates at a DS?
5. Any tips you want to give me before beginning my new position?

Thanks in advance!
