First applied online and had to write an application essay stating why I wanted to join TFA. Next I participated in a phone interview where I was asked questions about my organization skills, professional background etc. I was invited to participate in the final in person interview which includes presenting a 5 minute sample lesson plan, participating in some group activities, taking a small skill/data analysis quiz, and finally a one on one interview. The sample lesson plan was pretty straight forward. Remember to engage your "students" and find a way to check students for understanding. 5 minutes passes really quickly, so don't try to teach more than the time allots. The group activity and individual quiz are pretty straight forward, just be sure to participate and present your idea clearly in both. The individual interview was really comfortable and conversation flowed nicely. Expect typical interview questions - the type you can pull off of any interview prep website, also expect teaching related questions (since this is for a teaching position). Everything is really quite straight forward as long as you take time to think about typical interview questions. Keep in mind, they want to invite everyone who qualifies to become a corps member, so you're not competing with the other interviewers, everyone wants you to succeed.
