Out of curiosity, what were some of the differences in work culture you experienced? I've never worked outside the U.S., so would be interested to hear a different perspective.
Not OP - but I've worked with American and non-American tech companies. For similar-sized companies, my experience was that American companies are more obsessed with productivity and metrics, with more frequent meetings involving people who don't need to be present (including at least one one who is a level or 2 too high, but justify their presence by having to say something which occasionally derails the meeting).
On a purely subjective note: American work culture has lower trust and attempts to extract much more "productivity" from people doing the work compared to European companies, which is not always proportional to the salary differences. My sample size is fairly small (<5)
