This 100%. Really the only reason to work at a startup as an engineer is if you really want to, because everyone pays low and the tiny bit of equity is essentially worthless in 99% of cases, which gives it a very low value.
And, if you exit the company -- either voluntarily or involuntarily -- you often only have 90 days to exercise your options. If you've gotten laid off, eating into your savings while searching for a job is a pretty risky proposition. If you have an appreciable amount of equity, that bill can be rather high. Then there's AMT. Many end up letting the options expire. So, taking that pay cut for equity really didn't work…
This is why I advise everyone that you must early exercise (exercise your option as soon as you start with the company) if you're going to join a startup.
Some startups don't let you early excercise. Run far, far away. Find a different startup. Never join a startup that does not let you early exercise.
