I think it depends on the size of the company rather than the city the company is located in. I moved 800 miles to my current location, a city of 80000 in Oregon. My Employer paid to fly me out for the interview. I was also re-reimbursed for the move as well. The company is an international company with HR policies in place for moving people, there was no issue about my move. The only constraint from the actual city was the fact that vacancy rates for rentals is < 1%. Its pretty near impossible to find some where to live.
