How does MS helps with breaking into specific domains like OS/Compilers/Hardware?

I'm close to complete my Masters and there was basically nothing that'd help with those directly

Generally the whole Masters was mostly wasted time, the only good thing was that there were some people with different backgrounds/domains, so that was cool to see their perspective.

@OP check sylabus and ask graduates about opinions, but remember that you're already experienced, so probably more skilled than average student
