Free Code Camp will help you prepare for a coding job.
You’ll still need to develop basic interviewing skills and soft skills (if you’ve been working a knowledge-worker type job for a few years, you probably already have these).
You’ll also need to work hard to network with coders in your city. You can do this by joining your city’s Local Group and participating in as many events as possible.
I’ve found this link to be useful. It does a great job of explaining the process.
