They tell you how hard and long the process of landing customers and building a book of business can be, then give you 2 months to hit a goal (if you don't, they fire you), and if you hit that one, then you have 2 months to triple the total you just hit (if you don't, they fire you). There is no questions asked about your firing, you'll know when it's coming, you'll be short of you goal and start having weekly one on one's with your manager, and then one random Thursday or Friday, poof you're donezo.
