I just want to add the following to this discussion:
How is that someone who is normally happy, passionate, outgoing and bubbly can suddenly turn into a boring, stuttering, drab and monotone person while in those tiny, windowless interview rooms that they put you in for on-campus interviews???? I typically smile a lot when I talk about my work and passions because I enjoy them, but when the interviewer did not smile back I started in a downward spiral of self-doubt....maybe she's not smiling because I'm boring her, maybe she's not smiling because I keep smiling and it makes me look like an idiot, maybe she doesn't like me, maybe.......oh goodness how do I salvage this conversation???? Then what you had practiced with others that amazed them is now suddenly sounding so boring and...oh crap is that a stutter? Did I just blank on an important word that would make me sound intelligent and am forced to use a dumbed-down version that makes me sound like I'm in kindergarden? Did I really just wave my hand like that and my voice get that shrill.......
Sigh! Why are b-school interviews so weird? I've interviewed for jobs before and they were no where close to this level of intensity......
