Apart from preparation, positive thinking is also a very important key for successful interview.
I would suggest you to repeatedly say something like "I can do it! I am the best! I've got the right skills, quality and experiences! If they don't employ me, it will be their loss; not mine! If I do not get this one, I can get another better one" loudly, before leaving home for the interivew. You need to say it facing a mirror as loud as you can until you have believed what you are saying.
It worked for me. Hope it would work for you as well.
Good luck on your next interivew
