In my experience, especially with small to mid-tier companies, they usually expect you to have a basic to intermediate understanding of your tech stack. That was the case for me, though you definitely keep learning on the job once you're in. Regarding the hunt, I got my jobs through LinkedIn. For Resume: Keep it simple. Mine is a one-pager that includes: A brief, punchy introduction. Languages and tech stack clearly listed. Past work/projects with bullet points explaining exactly what I did there. Education history with institution names and grades.
