Same with me. My solution - just think you got rejected. This way u'll stop thinking so much about the result/call for interview and focus on the work at hand. When the actual result comes out, if you are rejected - it won't be that disappointing since you are already prepared for it. If you are selected, it would come like a pleasant surprise.
A little tricky, but effective. Definitely eased my nerves! Try it if you like.
