I applied online. The process took 2 months. I interviewed at Teach for America (New Haven, CT) in Oct 2013
Interview
The process is known for being rigorous, and the reputation is deserved. You turn in a few essays at the beginning with your basic stats, and then they might call you for a phone interview. Then you go to an in-person group interview where you must give a 5-minute sample lesson (demonstrating that you know 5-step lesson planning), talk about an article related to education, and do a 1-on-1 interview with a recruiter.
