For the record, its hyperhidrosis, not hyperhydrosis, and I think I have it. I have read that it is also closely related to reddening in the face. If you read Atul Gawande's Complications, there's a chapter on the latter, also mentioning hyperhidrosis in this context. In the chapter, I found interesting advice in stemming redness, which might work for sweating as well. That is to try to make yourself blush. The sweating and blushing response is actually contained in this method.
Relaxation also has something to do with it. Intentionally slowing your breathing by taking forced shallow breaths will calm you down because you're taking in less oxygen, and the more you practice, the better you are able to control your body.
Lastly, pad your pockets, all of your pockets with once folded paper towel pieces, cut so that they fit neatly. Then use as needed. Just quickly slide your hand in and press down. Another favorite of mine is very absorbant socks. Toward the end of the interview, or the beginning if you are a gregarious person, you'll can swing your leg over in a cross and hold one hand on your ankle in a typical respectfully interested pose, at the same time sponging all that ooze.
Lastly for the second time, smile a lot. I have not found any studies verifying this, but then again, i've never looked. However, I feel more open when I smile, and the more i distract them with crooked teeth and piece's of last night's dinner, the less attention i'll bring to my problem. Although problem is a misrepresenatation because we hyperhidroids have very efficient body flushing.
And one more thing, if you don't have time to do the ceremonious wipe before you shake someone's hand on first greeting, don't you dare give them a weak or half shake.

If you try it, be sure to PM me with the results. While I don't sweat much, it's an interesting experiment.
