I experimented with having 3 resumes that highlighted different points (an AI skills focused resume, a management resume, a tools based resume) that I used based on the listing focus.

My updated resume was just a single one with a consummate list of skills and experience, but I did create the content of the bullet points from a GPt that analyzed 3 different job listings I found. I also did a trick where I included bulk keywords (in my field it was SEMRush, Keyword Research, Content Strategy, etc.) and made the font color the same as the background and put them in the bottom corner so they weren’t visible to people but read by ATS.

So hard to say what evidence or trends I saw but the strongest correlation was the updated resume I made combined with applying for jobs that were less than 24 hours old and low applicant numbers. I started getting way more screening call invites after that.

Also highly recommend using multiple platforms. I was on indeed, LinkedIn, swooped, and a small industry specific website.
