Sounds rather evil....
What are they trying to select for here? Are they hiring all 18 year olds, or does someone in their 30s, 40s, 50s or beyond need to justify themselves slacking when they were a teenager in the eyes of management.
On the other hand, a lot of people that did well when I was in HS are the same who would diligently perform this sort of busywork no questions asked.
That's exactly what they expect.
Anecdote: MS was part of the tail-end of my interview process and after I brought up that it was a bit much asking me for justification of decisions I made decades ago, he stated - I'm paraphrasing here - that he believes that someone's decisions at that stage of their life are consistent with how they will react and respond later on, which is why they ask the questions to begin with. I nope'd on out afterward.
Only advice I can give is beware companies that cultivate a cult-of-personality around one or multiple execs. You will be required to drink the Kool-Aid and - when you invariably don't - that's that.
Now take this personality test. Now do this other crazy thing.
