I've spent a lot of time honing my resume and reading on the hiring process even if I've rarely sent out my own, so while I have knowledge, everything here should be taken with a pillar of salt.
In general, hiring managers will be looking for resumes that are focused and relevant to the company's interests. What are these interests? In order, I think:
Relevant employment in an official capacity with documentable history
Relevant experience in an unofficial capacity like hobbyist work, personal portfolios, etc
Relevant skill set
Irrelevant employment, as in semi-related or unrelated fields, at the very least they like to see that you can hold down a job
Somewhere in there is education level. I get the impression that education is used for broad phase culling for a lot of white collar jobs. At the same time, the recruiters don't really care about the courses you took, since one person's Discrete Math 1 isn't the same as another's. It doesn't tell them anything concrete. The only time it makes sense is if you're applying for an internship at the entry level with almost no experience to speak of.
Nowhere have I ever read that recruiters care or want to hear about your hobbies. Selling yourself, as a person, is the point of the "cover letter", and even there your writing is supposed to target to the position you're applying for, and not to create some sort of dating profile.
Anyway this mostly applies to America, and specifically to white collar work. I have no clue how it is in other countries.
