I'm a long time lurker but a first time poster. I stumbled on a great technique to find alumni from Non-Target schools on Bloomberg the other day. You can find relevant professionals in investment banking,, private equity, etc. by using the "PEOP" Bloomberg search function.
This was by far the most efficient way that I have ever been able to find alumni from my very non-target school. Utilizing this technique easily doubled or tripled the amount of relevant alumni on my list. Feel free to reply or message me for any questions. I am curious to hear if other people have used this strategy as well.
