Here is a list of things not to do:
* Don't waste time using employer online career portals. These only continue to exist to satisfy EEO legal requirements. Most employers don't respond to these.
* Don't pad your resume. Make every line of your resume count as if it were being read by a human. With AI tools now filtering resumes they are getting better at bullshit detection.
Things to do:
* Upload your resume to places like Indeed, Zip Recruiter, Dice.
* Be very specific on your resume. Yes, you should state something about your tech stack in the fewest possible words, but anything related to competences should be expressed in quantifiable terms only. For example you saved the company billions of dollars, or shipped 200 features to production, or reduced execution speed by 50%
* Be clear about your experience and what you are looking for.
* Have external credentials like PMP, CISSP, security clearance, and more. These open doors for you that you currently don't realize are closed to you and likely pay more.
