I liked to imagine astronauts as individuals who excelled so much in their given fields that they stood out and were actively recruited by NASA. Instead, I find out that NASA posts job postings and interviews people just like everyone else. This would be mildly concerning other than the fact that it appears to be working.

Edit: I wonder if they are asked silly interview questions such as "If you were stuck on the moon with only three items, what would you want them to be and why?"
