That's a good question. I'm English and I work for a UK company. I had some reviewers at the 50% stage who were from European companies and they didn't say anything specific about this, but I'd be interested to learn more about the US tech scene being quite alien - I haven't experienced it myself.
And for me as a Swede the most alien thing for me is the "lone genius startup"-thing (that probably is very over represented/emphasized here at HN) where developers work for stocks(?) and hope(?) that the company will blow up and seem to take great personal risks. Of course that exists here as well in small startups but we have so strong work force-regulations that I don't think it can get that extreme. And now that I think of it it might be that we are the odd ones so maybe it's not so much u.s. vs. e.u. as u.s. vs sweden. ¯\_(ツ)_/¯
