CAREER GUIDES

Long-form guides for serious job seekers

Practical, evergreen guides on cover letters, resumes, ATS optimization, and what actually works in 2026 hiring. Written by the CareerThings AI team.

Cover Letters

Most cover letter advice on the internet is identical, vague, and 10 years old. This one is different. Below is the exact framework professional recruiters use to screen cover letters at scale, the structure that consistently moves candidates forward, and concrete examples for entry-level, mid-career, and senior roles. Read it once, write yours in 30 minutes, and never write a generic cover letter again.

ATS & Resumes

Most "beat the ATS" advice is recycled, misleading, or both. The truth: ATS systems are simpler than people think, but the rules for passing them are real. This guide explains how modern ATS actually works, what matters (and what doesn't), and the exact optimization steps that move resumes from filtered to forwarded.

The resume summary is 2-3 lines at the top of your resume. It's the most-read section after your name. Done well, it gets the recruiter to read the rest of the page. Done poorly, it triggers the skip. This guide covers the formula, the common mistakes, and 12 concrete examples to model from.
