Is it this one? https://www.coursera.org/learn/user-experience-design#syllabus
I've had a quick check on syllabus and it seems a bit vague but it sure is a great start for the first step! You're on right right path. And if you find it a bit boring, most of the time, it is. There are great resources out there and you've found a decent one. Beware tho, there are same amount of shit resources pretending that they're the best as well.
If you want to take a step further (and pay a bit) there's neilsen norman group's cerftificate programs and there's this a bit more 'hipstery' but actually good hyper island programs as well.
Also I'd suggest you to start reading this book, it's the bible for ux design. Design of everyday things Make sure to get the yellow one. Black one is a bit older and it's real life examples based on pull-switch fridge handles and folding bus doors. And the yellow is more upto date and talking about with smartphones and electric cars etc lol.
For degree thing, yeah you don't need to confirm unless you're going to apply to an ultra-corporate company. And that's for HR thing. UX and UI outputs are pretty obvious comparing to other branches. I mean if there's a literally product you've released that's a solid proof. That's the working, functioning thing that you've made up and that's exactly what's expected you to do when you get hired.
There are tons of visual outputs when you work on a project. If someone happen to steal someone else's images, just a reverse search on the image would reveal the original poster. Therefore it's a bit hard to lie. Some do give tasks to do before hand tho. Be careful not to spend too much time on them tho. Some companies use this privilege to finish tasks for free.
But at the same time, there are lots of pro social engineers that lie through the interviews but they tend to crash during their work experince (then they end up writing blogs and giving speeches like they've found a cure for cancer)
