The best way to get hired here (or anywhere really) is to be referred by a current employee. I just went into the office one day and handed them a resume letting them know I'd love to work there. After that they scheduled an interview with me. I had to prepare a math concept that I would teach in the first interview. Once I got the second interview, they provided me with a list of concepts in advance that I needed to be prepared to teach during that interview. If you have people skills and know your stuff then you should do fine. This company does receive a lot of applicants and is picky about who they hire. So if you pass both interviews and are offered a job then you should feel pretty good about yourself.
