The case for cover lettters

What It Covers

Jason Fried explains why 37signals requires cover letters for all job applications, how they screen 1000+ candidates by evaluating writing quality first, and detecting AI-generated submissions through pattern recognition.

Key Questions Answered

• •Cover letter priority: 37signals reviews cover letters before resumes, requiring applicants to demonstrate writing ability and genuine interest in the specific role rather than generic job hunting, immediately filtering out candidates who cannot communicate clearly in writing.
• •AI detection method: When reviewing 1000+ applications, patterns emerge in phrasing, structure, and punctuation that reveal AI-generated content. Using AI as an editing assistant after writing is acceptable, but having AI write the entire letter is grounds for rejection.
• •Standing out strategy: Only 10% of applicants put in extra effort beyond basic requirements, and 5% go significantly further. Small additional work like designing a custom presentation or writing a thoughtful personalized letter dramatically increases chances in competitive hiring markets.
• •Application timing: Most applications arrive in a curve pattern with high volume at opening, low middle period, and massive spike before deadline. Submitting at the last second signals poor planning and risks technical failures that result in automatic rejection regardless of circumstances.
