If you are joining a public company, any stock options you may be granted are easily valued. This is simple math, but you still have to factor in your vesting time and how long until the options expire. This kind of option grant is real and the benefits are tangible. They represent a measure of your worth and recognize your contribution to the company's success. Best of all, these options are generally awarded independently of your cash compensation.
Startups are another story.
These are the wannabe companies, ranging from two guys with an idea working out of their buddy's basement to professionally managed enterprises with substantial venture capital funding - and every possible permutation in between. Their one commonality is that they need talent to get where they are going. And that's where stock options come in. And that's all good when it comes to burn rate. Cash flow too.
