I like this approach. Troubleshoot what part of the job offer journey you are blocked it. In addition to the advice of 'Find Out', which can be in the form of the OP making a post and doing the above advice, one one area I see other Engineers who are out of the traditional Engineer path often neglect is reaching out within their network.

OP mentioned previous employment and having an undergraduate degree. Is OP still socializing with anyone they met in those environment. Is so talk about this goal to get back into the tech industry and ask for advice and execute. Show your network that you are trying so they can give you feedback.
