I think the value is mainly in the feedback you get which can help if you have a specific problem you might not be aware of. The problem with just going out on interviews is that you never get any real feedback so you are left to your own analysis as to why a certain interview didn't result in getting to the next step or an offer which, in my experience, is kind of like trying to find a needle in a haystack in a dark barn without a flashlight.
