Would you be relocating, or staying in Europe? If you stay in Europe, time zones will come into play, so be prepared to take some late shifts and very heavy afternoon meetings. We are remote-friendly and I have many Euro colleagues however because our corporate is here, they do get the short end of the stick for scheduling.

Would you be taking the company's benefits? Another thing I've heard a lot of culture shock regarding is health care premiums from EU people who've relocated here.
