I've worked in the industry and gotten multiple job offers over the years from them. It still blows my mind that >50% of your compensation is issued as a once-per-year completely-discretionary "bonus". It mostly works fine, due to firms wanting to safeguard their reputation. But if for any reason, you piss off the wrong person or the firm has a bad year, you will lose 50% of your expected compensation... retroactively for the work you had already done in the past year... with no legal protections or recourse whatsoever.

Sure, tech companies have significant bonuses and RSUs as well. But the bonus is more limited in size. And the RSU vesting schedule is more fine-grained, explicitly defined in your employment contract, and the stock valuations are determined by the wider market.

Imagine working in finance for a year, expecting to earn $300k for a year's work, and then finding out at the end of the year that you're only going to get a fraction of that. It blows my mind that this doesn't scare more people.
