The process was very thorough. There three separate interviews. The first was with HR, who had reviewed my application (which consisted of a a range of questions provided by SP) and talked with me basically to find out if I would be a good fit for the company.
After this I did a second interview, which required me to first prepare answers to a list of questions sent out over excel, analyse information in a power point, and analyse one of their existing games.
Finally a third interview with the most senior person in the team who was again trying to assess if I was suited to the team and talked about my experience and ambitions.
