It's terrible. You tell me what's more important as a first hurdle: getting cookie-cutter answers out of players with some weird personality test, or putting them in situations that they'll actually be in as a GP and seeing how they'd handle it with no training or experience. You know you can gauge how well someone's English and maturity level is with the latter too, right?

It's so easy to BS through that application and it's setting you up to hire people who seem "nice" rather than people who can do the job properly. These are the types of questions you can Google to get good answers to. You can't do that with questions that are specific to Graal or being GP.
