My son spent three weeks with 25 NASA astronauts a couple years ago teaching them to use their suits and subs as training for their NEEMO project. After his three weeks I asked him what they were like as people because they all lived, worked and ate together as a group. (Because if it was me, not gonna lie, I'd be as arrogant as hell if I was an astronaut)
He said they are as a group some of the most amazing people he had ever met. Smart, caring, kind, team oriented, and welcoming. He said they were like a group of super-humans.
They were telling him some of the selection process is just a massive personality test to see how they interact with others. He really enjoyed his time with them. He laughed when one of the astronauts said "You have a really cool job", and Jared said 'You've been to the ISS and you think my job is cool?"
Three weeks after his time with them he got a call from the NASA recruiter talking to him about the application process and what he would need to do to apply because they all thought he would be a good fit for the program, personality and brain-power wise(takes after his mom, not me)
