Thanks for the replies guys, I really appreciate it.
To answer coakleym's question above, I graduated in December of 2008. So when I apply this September, I'll only have had 1.5 yrs of experience and 2.5 yrs at matriculation. I feel that this amount of WE will do nothing to mitigate my GPA, however, I hope it doesn't hurt me. What do you guys think? I definitely have an interesting story to tell (interesting to me, at least) and I'm an international applicant and not Asian or European.
Oh, and my major was Economics, so not Engineering. That won't help me much in terms of my GPA other than the fact that Economics at my university is a math-intensive major (less so than Engineering, of course). I also hope to get a 700+ on my GMAT, so that should help. I should also add that I'm applying to the top 15 US universities + LBS, Oxford, and Insead, with Columbia as my top choice.
Anyways, my follow-up questions are:
1. Will 2.5 yrs of quality WE (not at blue-chip) hurt me?
2. Will 3.22 in Econ look bad since it's not as hard as Engineering (some would say)?
