I'm a male junior in undergrad, hoping to take part in the Summer Intern 2013 recruiting process. I'll be nearly 21 during the interview period (Q1 2013).
I'm worried that people won't take me seriously because I look like a kid. Like, a high school kid. I'm a shade over 5'9" (without shoes), about 140 lbs. Also, I have the face of an 18 year-old (most people guess 18, but I could convince people I'm 16 without much trouble). Moreover, I can't grow enough facial hair to look any older. I'm not even cut either, but I guess that doesn't matter when I'm in a suit.
On top of that, I sort of act like a kid. I'm not stupid or immature (far from it, actually), but I'm a naturally high-energy/optimism/all-round cheery kind of guy (I know that sounds kinda gay, but I can't really tone it down for interviews e.g. I smile quite a lot etc.) It's the amount of energy you'd expect from an eager HS student, not a world-weary college kid at a target.
I was doing an internship at a boutique this summer and everybody there was very nice and willing to help me (both with what I was working on, as well as general career advice), but it also seemed as if they were being overly nice, as one might be to someone they're babysitting. That's how chicks treat me at clubs too, even if they're my age.
My question is, in a business (I'm aiming for) where
1) everybody is somber, looking older than you are is valued, and analysts age much quicker than the usual due to 100-hour weeks
2) People are supposed to be tall, jacked, white (I'm not white, or American, actually) Alpha males
Do I have a shot with my just-a-few-pounds-away-from-being-mistaken-for-a-girl-from-the-back-and-male-jailbait-from-the-front body and stupidly sunny disposition?
tl;dr - I'm a guy, turning 21, who's 5'9", 140 lbs and w/ the face of an 16 year-old - does looking like a scrawny little boy who should be preparing for my SATs equal an autoding at?
