There's definitely a problem there, I agree. In practice, the people that we take to that stage of the interview process typically have quite a lot of self-awareness and also know a fair bit about our company by then, so so far it's worked out alright. But I definitely see that that could be a problem with some people. As I said elsewhere it's not something any company can just implement without thinking about it and have it just work. It takes a lot of work in many areas of the business.
