I applied online. The process took 2 weeks. I interviewed at MathTree (McLean, VA) in Jun 2011
Interview
If you email them, they send you an application and once you return it, they call for an interview. Overall, they are a great company but it seemed rather unprofessional how they hire. Also, you can have an assistant who gets paid more than a teacher, which was odd. I was hoping that we all start at some ground number.
Interview questions [1]
Question 1
No difficult questions - mostly pertaining to how you teach the class, what is expected of you, etc.
