Never took a job with "unlimited vacation" but had interviews with a few of such companies. Right now, I get 4 weeks off with unlimited sick time.

So during interviews, I asked them about "unlimited" vacation policy and how many days they took off last year. It is almost always less than 20 days. When I asked them why they didn't take more days off and that I got 4 weeks of vacation plus a few days of sick time off. They usually make up excuses like it was unusually busy year, don't feel the need for more vacation, or it is still more than most people took off last year.

Or sometimes they are honest and say that they feel guilty asking for more time off, hard to get approval for 3rd week off, they rather have fixed number of vacation and not feel guilty about using all of it.
