Deferred compensation is probably not relevant to any of the major quant firms, payment is almost entirely cash. If you're high enough up to start receiving stake in a prop firm directly as part of your bonus you are an order of magnitude above the TC cited by the original comment.

Of course, the amount of comp you can get is a big reason people stick around. For that level of earning potential JS is really good on the WLB front. But it's not going to be as good as big tech is (or at least has been), since QT/QR just has different requirements as a field.
