Our graduates get jobs raging from S&T, structurer, risk managers, quant developers, etc. Both buy-side and sell-side firms. Here is the list

I'm interested in buy-side jobs myself, either in structuring or algo trading. I've talked to some people and they all told me that the shift is going to buy-side. The reason is because of the advantages technology provides. The technology makes the market a more even landscape for buy-side firms. Price comparing is more efficient than ever.
If you see how all the big exchanges go electronic, you will see that outcry trading is not the future. Instead, algo trading will be where it's headed. It's just simply more efficient operation-wise and profit-wise. Also, the thinning bid-ask spread contributes to the trend. If you can squeeze a fraction of a cent out of every trade, and doing millions of trades, it adds to the bottom line.
That's where I think trading is going.
If Fortress is any indication of what the future is like, then hedge funds or "private investment funds" as they prefer to be called, will dominate the market in term of the volumn they move in and out everyday. I think Citadel and other hedge funds will be the big players in the future (if they are not already).
So they will need skills that are highly technical and specific. We learn to structure and dissect deals. We learn to manage risk. We learn to build models. These skills even though are fundamental, can be highly appreciated at most places.
You are right in asking about buy-side specifics. That's where the future is. There is little growth in sell-side. I read an article comparing the growth of buy-side and sell-side during the last few year and the difference is very impressive.
I'm not sure if I address your question at all. These are my own opinions that I form based on the info I have. I maybe totally wrong because I don't have experience working in the industry. I would love to hear from others with more firsthand experience, specially alumni of our program.
