I'm reading through the book now and the besides the signalling vs human capital argument the most interesting part is how he breaks down
what college students are signalling into 3 parts that companies are interested in.
1. Intelligence - By passing tests
2. Conscientiousness - By doing it for 4+ years
3. Conformity - By not figuring out a way around it
It's an interesting exercise to think of how different careers might value these 3 factors plus human capital differently.
