I applied online. I interviewed at Information Development
Interview
Very straight-forward. First there was a rather casual interview, then an aptitude test (similar to SAT math section plus a personality test) followed by a formal interview in Japanese. Depending on your level of Japanese, you might be asked to do the casual interview in Japanese as well.
