That's the challenge in all engineering interviews - determining weather they did anything useful or were just on the team. I've had to tell people to stop telling me about "we" and tell me what "you" did. Some people are so caught up in trying to be a team player that they hide their contributions. Others use it to hide their lack of contribution. It's not hard to separate these once you're aware of the issue and start asking the right question "what did you do?"
