Unfortunately, I'm one of the old 'I fell into it because I had experience in both the field's components (tech and education)' stories: I've been coding (mostly but not exclusively front-end) since the 90s and been teaching techy things on and off about that long (I taught my first programming class in '99 when I was 11), and then I went and worked in libraries/studied how people learn outside of formal classroom contexts.
So I already had all the skills needed once the field started. I cheated.
If I were getting started now, my advice would be to remember that the human element and the tech element are of equal importance in Instructional Design. So you'd want to take stock of what skills you currently have and how best to a.) get the necessary knowledge you don't have and b.) take advantage of your particular skill set.
Since you're on HN, I'm assuming you're of a techy bent vs. an educational/people bent. So if you have any teaching/tutoring/etc experience, I would lean on that. If not, I would get some. You can do this by volunteering somewhere + doing some basic research. I highly recommend this since a large portion of instructional design (like most front-end things) is planning for all the weird things humans do when interacting with your stuff and, more importantly for instructional design specifically, how people who can't computer at ALL think. When doing ID, you're often designing for people who can't figure out how an email works and are taking a work training, for example.
Also since you're techy, I'd recommend spending some time with UI/UX and specifically focus on designing for different populations/audiences. From a tech perspective, your competing instructional designers are worst at the 'boring' things like accessibility guidelines, making sure things can run on terrible machines, coding fall-backs, etc. So a tech background is of great assistance as long as you communicate the problems it can help you avoid.
As for the actual 'how to get a job', I literally applied for my first job off of Indeed out of grad school and I'm a first-generation student so trust me that was not the most polished resume or CV.
