My application took about a month before I recieved a reply from Playstation. First is a phone interview which took about 10-15 min, followed by a face-to-face interview at Liverpool.
As there was nobody who could speak Korean to assess my Korean skills, a person from Korea came to ask questions.
The overall interview took about 30 minutes, half of them in English asking questions about myself, while the other half was in Korean, asking questions on how I would respond in given scenarios.
