Is the ratio of compensation really 2-3x?

One datapoint: Senior Dev (say Level 1 Senior) base pay is $100k. So are you saying SF will pay this person at least $200k?

Yes. Junior dev base pay in SF is 100k. I know junior devs here making 130k. Add RSUs, factor in the exchange rate... the multiplier is easily 2-3x.

Yes, seniors usually get more than 250k at established companies. Provided you can make it in as a senior.
