I applied through university. The process took 1 day. I interviewed at Tecmo Koei Singapore (Singapore) in Sept 2016
Interview
A series of IQ tests which can be pretty tedious. This includes a programming test(not critical for game designer), IQ test, database questionnaire, and a final 6 part IQ test. Also an interview with their staff.
3 layered interview, interests and strengths
to state knowledge of company's games and relevant language and practical abilities. fairly casual interview that identifies where you would fit in the organisation
The process took 3 weeks. I interviewed at Tecmo Koei Singapore (Singapore)
Interview
There were 3 stages of interview.
During 2nd and 3rd interview there was video conference with the japanese office.
They always got back to me within a week after each stage.
