What's the vibe like in the Sales dept at Zayo Group? How many hours are you working?

It's a Sales role. You work as your customers need you. Is there an internal expectation that you're working past 9-5? Not really. But just like anywhere else, you'll be expected to be externally responsive when you need to be. That said, there is a lot asked out of Sales here that goes beyond direct quota attainment activity - some of it is productive, some of it is questionably productive - and it is unlikely that you will both make quota sustainably and also hit your other KPIs working only 40 hours a week consistently.
