I did this my senior year of college, looking for software engineering jobs, although I used Google AdWords instead of Facebook ads. I knew I wanted to work for a startup in the Boston area, so I bought out search terms like "Greenhorn Connect," "YCombinator," etc. Whenever someone in Boston searched for something that a startup manager might search for -- I was there.<p>I got a ton of responses, and ultimately a couple of offers out of it. Unfortunately, I took a job at a consulting firm right out of college (hated it and left 6 months later) -- there's only so much you can do to solve problems of 21 year old stupidity.
