These are always so weird to me. I grew up in the rural south, and I’ve never once heard Coke used to describe soft drinks generically. In my experience when someone asks for a “coke” they specifically mean Coca Cola and would be pissed if they got something else.
You gotta make it a point to ask what the pay range is in the first interview or you’re wasting your own time. If they won’t tell you, the job isn’t worth your time anyway.
