It’s not about doing it for “fun”, it’s trying to reframe things that people can have a lot of anxiety around because of their importance. When you’re very nervous, you lose your confidence, you might lose your train of thought, you might not get a good night’s rest leading up to it, your stomach could be in knots, etc. your performance suffers and you don’t seem well put together to others. If you can go into an interview with a mindset that it doesn’t matter, that weight is lifted off of you, it helps you keep your cool and you won’t self sabotage.

You gryfindor scum would say that!
