I had two interviews and got turned down after the second one. The first was a very simple interview with a human resources associate who worked in consumer insights. He asked me a few questions to get an idea of my game knowledge as well as how my skills would apply to the job.
The second was a more in-depth interview with the research manager. She asked typical interview questions but then she presented hypothetical scenarios about the game on how you would gain insights from it, particularly what survey questions I would ask to participants to get an insights about a particular topic. There were also questions about applied survey methodology as well.
