Short answer- Yes, it would certainly deserve an interview at least. But that is speaking as a hiring manager, I am not sure how internships work. The thing that struck me was "Everyone on the thread agrees the letter shows energy and pluck and honesty." I couldn't help but think it's a shame the latter quality would make him a poor candidate for a Wall St. job. Wouldn't honesty automatically disqualify you?

Of all the hirings, and interviews I have done, this individual would move to the front of the line.
