I'd be able to help you with this, I've done this for a few others in here. Just PM me your essays.
I applied and was rejected at Kellogg last year - I was wondering if any one is willing to look over my essays from last cycle to do a 'post-ding' analysis so I can figure out what I'm doing wrong.
I think - my essays weren't focused enough, and that my short/long term career goals aren't clearly shown in the essays, but I'm sure there are lots of other flaws as well.
Please leave a message here if you're willing to help and I will PM my essays to you.
