On a side note, what are higher ups looking for in a young applicant? I'm graduating in the fall with a CS Undergrad and don't have any startup contacts (I live in a smaller town in Missouri) and am trying to get my foot in the door somewhere that is doing interesting work.
Any interview I walk out of thinking I've had a 2-way meeting of minds, a genuinely engaged conversation as if we're already peers, rather than an attempt to simply answer a list of questions is going to do well.
