Earlier quoted context omitted.
I've recently interviewed and got 5 offers. Those numbers check out.
All SF/CA numbers I suppose? Any idea how these differ in Austin?
No idea for Austin, but I used levels.fyi to give me an idea of what to expect and negociate, and it helped a lot (and was on point with what I got offered). I think you can filter per city, so there might be some data for Austin.
