I think my biggest weakness is the number of years of experience(3.5 years by August 2014) and also being in a pool of engineers. Any ideas on how I can strengthen my application?
Another work recommendation?(the original recommendations were from non-profit) or recommendation from a non-profit am working with or both?
Had mentioned this in the other forum but makes more sense here:
@WL folks : Last year I was WL twice, before being rejected on the last before school started, so I know how you guys feel. Hang in there.
One thing you guys could do is to either redo one of your essays, which you think might be weak or write a new essay about a Haas principle. I had submitted an essay last year about how I exemplified a Haas principle, that was not covered in my first app or interview. During my feedback interview, the Adcom person mentioned that it had a positive impact on my app last yr (obviously not positive enough!).
If possible, have your manager write an additional letter which shows Adcom that even though you don't have much experience, you are taking on tasks which a senior person might do. That might help mitigate the lack of experience a bit.
Best of luck!
