I also thought i'd mention since you came on PC and thus, chances are, are mentally ill... there is also the possibility of depression doing you in. I do not deny inexperience being a factor but also consider the factor of depression. I am naturally fine socially, most of the time, intuitively knowing what to say and when to smile and how to be charming, but not when depressed. I lost two interviews a year ago despite having a perfectly fitting resume, and when I look back, I see two common factors. I had strong visible hand tremor from Depakote (which I have since dropped) and I was depressed and lost. So I did not shine. Employers do not want to hire girls with poorly hidden sadness and despair in the eyes and shaking hands. And not just employers. Keep it in mind.
