Even if you interview "for fun", there's still a chance that you'll be so enticed by what they offer that you'd accept. There's nothing unethical about interviewing for a company that you don't think you'd want to work for -- it's their job to make the case that you should work there. But this isn't the case if you're paid by another company to go to the interview and you are forbidden from accepting an offer.
