The application process has multiple steps. Beyond an initial application where you answer a few general questions [why do you want to join Teach For America], you are basically submitting a resume for the first round. Then, if you are moving forward, they will contact you for either a phone interview or to let you know that you are advancing to the final round. They state that getting a phone interview does not mean you are somehow not 'as good' as someone who advances to the final stage, though it does introduce one more opportunity for you to be eliminated from the process. The final interview is an all day commitment. I don't have specific knowledge about the phone interview because I advanced to the final round. In a room with about 10 or so other applicants, you will have to present a 5 minute sample lesson. The key to this portion is your ability to name a specific objective that you will teach and literally achieve that objective such that you can demonstrate student mastery of the objective. The other applicants role play being your students during this portion, in addition to the interviewers who tend to take on 'adversarial' roles. Afterwards there is a group activity. The group has a limited amount of time to read a prompt relating to a school issue, such as expanding a program and seeking out approval from a principal who has every reason to say no. During this time, interviewers are walking around and listening/observing. This is not the time to overtalk/interrupt or 'be the boss', but rather demonstrate that you can work productively with a group of people. Finally, you will have a one on one interview where you are asked to discuss in detail how you manage tasks in high pressure situations.
