They're very polite and kind, you can get a lot of support with setting the interview date, and even if for some reason you miss it, it's easy to set another interview. Signing up is also simple, as outlined on their website. It may take a couple weeks after the interview to receive any word, but that may be because policies were changing when I applied.

Got a call from a recruiter in a call centre. Things started fairly normally, then got asked to teach a short lesson to the interviewer while she pretended to be a six year old who didn't speak much English. Easily the most bizarre interview I've ever had.
