I interviewed at the Boston Career Forum. Before my interview there were several aptitude tests online. I remember them being more difficult than others than I had taken, and I didn't think I did very well, but since I was granted an interview they can't have been particularly important. The first interview lasted about 20 minutes, and consisted of mostly general questions, nothing difficult, about myself, my interest in the company, my past experience, etc. The second interview was about 30 minutes and consisted of the kinds of questions you would expect to get in an interview (challenges you've faced, how you've dealt with failure, etc). I don't recall any point at which I was stumped by a question. Both interviews were in English, although I could (and perhaps should) have done the first in Japanese. The second interviewer did not speak business level Japanese.
