Priya,
I am assuming that you are interested in knowing more about consulting within sustainable / non-profit and development space.
Traditionally, niche companies operating in this space do not recruit in a structured fashion like traditional consulting firms primarily due to the nature of this industry. However, this year the Consulitng Club is focused on tapping companies in this space and is working towards getting them on campus. Further, there are no companies that recruit for emerging markets.
Hope this helps. Feel free to shoot any more questions you might have.
