The one offer I received is about half what I make now. I turned it down hoping to hold out for something better. I've gathered that one's salary will very wildly based on the country (Switzerland seems to be the highest). The loss of salary has been disappointing and something that I'm willing to sacrifice (there are other advantages that offset it, like work/life balance) but not so much that I'm making less than an entry level salary in the US.
This site looks promising so thanks for sharing. If there are any more sites like this, or recruiters that specialize in this kind of thing, I'd love to know.
