I think I kind of like your "dark side" maybe because of the brutal honesty that accompanies it. However, on the contrary, I love job interviews more than the jobs themselves. It always seem like an opportunity to sell yourself, to give sparkling ideas and leave an impression on your potent employer's mind that will make him/her think that you're indispensable.
It can also help expose your weaknesses and deficiencies. Strucking you with reality of the things you need to learn.
