The average job title got 69% longer between 2013 and 2025, stretching from 2.4 words to a full 4 words, according to BambooHR’s State of Hiring 2026. The easy read is that employers are getting more precise. The honest read is the opposite. When a company can’t say what a job is in two words,…
There’s a specific moment every job seeker knows. The posting is open in one tab, your resume is open in another, and you’re toggling between them like a customs officer comparing a passport photo to a face. Some lines match beautifully.
