I found my current job through the January HN Who's Hiring post. This company doesn't post anywhere except HN. Would definitely recommend that since the August post is coming out soon! This experience inspired me to build a tool that uses AI to match your resume to the best matching jobs: https://hnresumetojobs.com/
Give it a try, maybe it'll help you! Best of luck, it truly is a grind and is emotionally taxing -- but you WILL find something soon.
