Even with the higher cost of living in SF/NYC/Seattle, tech pay at FAANG is pretty high. Senior software positions are pretty much start at $300k/yr across all of those companies. Plus these companies generally have excellent healthcare plans and good vacation policies. At those income levels pretty much the only thing you’re really priced out of are nice single family homes, but I suspect that’s the same in Zurich.
What's a good vacation policy in SF? I'm tempted to move from London, but I currently get 28 days holiday a year + 8 public holidays + birthday + Xmas to NY (so about 40 days give or take). I know there's a lot of "unlimited" holiday policies - but would they really be okay if I took that kind of holiday? I earn a lot here in London, but moving to SF would be a significant bump. However, I very much value my time off…
The "unlimited" thing became popular in California in part as an attempt on behalf of companies to avoid having to issue payouts for accrued time off to employees leaving their organizations.
I'd suggest simply being very up front and specific in interviewing and negotiations about how much time you plan to take and see what kind of reactions you get.
