"After a couple of months at a company, a new grad may think “hey, this isn’t THAT great’, and not stick out the next 9, 10, 11 months, because that seems to them, an insanely long time."<p>Then he made a mistake during the interview process. Remember, it's not only them interviewing you, it's also you interviewing them. Bring up issues you care about (work ethic, work load, flexibility), and you'll have fewer surpises later on.<p>"On the other hand, for someone who has been working for a few years, 8,9, or 11 months might seem to be a much shorter period of time, and proportionally it is. They might stick it out, get equity, and become much more committed to the enterprise."<p>Yes, the company can issue additional grants, there's no law in place to say that what you get on day 1 is the only equity you're going to get, ever. The company can structure performance (equity for shipping major products) or retention (equity for 2nd, 3rd, 5th, 10th, 50th anniversary with the company) however it pleases.
