Except in rare instances (experienced hire with very rare and highly demanded specialization), the comp will be a given and take it or leave it. You will not discuss it in the interview, and probably will not discussed it at all, ever. Not in the US, not in Europe.
Expenses... also not in interviews. Surprised HR / recruiting didn't already bring it up, you should definitely ask them. BCG offered to put me in a Ritz Carlton, I can't imagine RB not reimbursing anything
