Harvard Business Review has some really smart suggestions! They include asking about “outstanding shares” (to figure out how much of the company you’ll own); “stock option vesting schedules” (how long you’ll have to stay to receive your equity) and “noncompete and non-solicit agreements” (do they own all of your work in and out of the office? BEST CHECK). Basically, if you’re joining a start-up to GET RICH QUICK, make sure that you will actually get rich at all. If you’re joining one because you need a job, carry on.
