At the end of the day its up to the employees to realize what they are getting into.

Typically for a tech employee when it comes to compensation the equation is salary + bonus + RSU/options. Its important when considering a position to think through each piece.

In regards to the bonus how does it get determined what the amount is, is it known upfront, does it typically get paid out at 100%, over 100%? What is the percentage amount for the last x years?

For the RSUs/Options if its an established company how stable is it, if its a startup then how likely is the success of the company (in my case if its a startup then I personally don't depend on this part of compensation).
