> "Doing that MOOC/Masters gives me a certificate that helps my resume."
I have to mirror an observation I've read on here that matches my retrospective view: Job applicants with multiple online course certificates tend to do poorly in technical interviews.
This may in part be a failing of our education systems. "Be taught about something -> write test -> pass/no pass" is usually all there is, and this system of how knowledge is valued becomes ingrained in students. Sure, tests usually contain sections of "applying" the knowledge, but ultimately it's still studying to and because of the test.
If you're lucky enough to be both versed in a subject and visit a school that provides extra-curricular engagement on these subjects, you may get a glimpse of what it feels like to solve a challenge because you want to. Otherwise you have do that completely separately from whatever formal education you receive.
It has personally taken me many years and several key experiences outside of school to fully grok that presentations aren't just condensing a topic you don't care about into a scheme somebody else dictates, held in front of an audience that would rather be elsewhere. Or that playing music isn't just about getting the notes and their volumes right. But now I deeply enjoy both. I would imagine that many are similarly stuck with a terrible mindset regarding learning or problem solving due to the way they were educated, even if they would find it exhilarating with the right frame of mind.
So yeah, show off your self-directed projects in your resume. Thrill your interviewers with the cool problems you tackled. Mention key challenges you overcame.
Without exaggerating too much, I would say online course certificates are as indicative of your technical abilities as a screenshot of a completed Tensorflow download. And that extends to the message you send if you include them in your application.
