What's the pay like for Sales roles at Zayo Group?

It depends if you're junior (not great) or senior (probably acceptable), but either way, make sure you are 1000000000% clear on the compensation plan before you agree to join. Too many people come into the organization thinking that the vagaries are all well and good and will still get paid straight-line on attainment when it comes down to brass tacks (not usually the case!). This doesn't mean the plan is bad (there is legitimately some real upside when the company is doing well) but it won't work for you if you have the wrong expectations coming in. Force the hiring manager to lay it out as it is.

Wide ranges commensurate with level of experience, skill level and account responsibility. Assume base will be somewhat below market and incentive comp at 100% will more than make up for it. Good luck getting 100% payout though.
