Theres an IV-drip of Kool-Aid in everyone's arm within 2 weeks of joining the company. You will likely be called out for disagreeing or bringing up any major changes. This gets tiring after a while.
The Sales org as a whole has good leadership in Mike Gamson, but the more down the ranks you guy the more egotism and BS you'll run into.
Also, don't expect meeting 100% of expectations to be even remotely close to enough to get you anywhere. Not only are the expectations high, but there will be people who are working twice as many hours as you, getting in way earlier, and achieving the same things, and thus looking better than you. There's a culture of working long hours even after the sting by the department of labor, and there were no managerial efforts to curb this. In fact, during meetings people would be praised as "rockstars" for being the "earliest to arrive" and the "last to leave." little work-life balance. Oh, you'll also be underpaid if you start in Sales Development.
They also have a trend of hiring a ton of really smart, motivated people from "target schools" (read: Ivy League and Stanford) and then not really giving them with anywhere to go after their first year or so. I can see this ultimately leading to frustration and burn-out.
