Fair points, though I don't know how high of an expected value I'd give to 50k of Box
options. It's hard for me to imagine that options given that late are that valuable. I'd imagine the equity compensation at lots of other places would be better.
Don't feel bad though, these high salaries typically happen at large companies in extremely expensive areas. So, the money isn't as much as it seems, and you likely will feel like a small cog in a giant-money-making corporation. In other words, chasing the money is often not worth it.
