Yeah... all those promises were what are technically known in the industry as "lies". You will never see a market level salary or even a raise, and once that 2% equity has been through dilution it will be more like 0.2% at most. Sorry, but there's no way this situation will play out well for you. Another thing you probably don't want to hear is that you are not "senior level" if you lack the experience to have figured this out for yourself. Not even close.

You can learn from this and never be played like a sucker again, but many people it takes 2 or 3 goes around to realize. But it's fine for the CEO, there'll be another 22-year-old around to take this deal in a year.
