They would have a few people in the room. A few supervisors. Ask what you have done in the past. The type of software you use and if you are willing to learn there software. After the interview, they do a week of "testing" and even during this week, you dont necessarily have the job. If at the end of the week, you don't preform at the level they want, you don't get the job. Kinda stressful for someone that has never done stereo-conversion before.
