Signaling theory · careers

No brand-name resume? Build the signal yourself.

Hiring managers defer to judgments already made: "they got into YC," "Google hired them." That's signaling theory (Spence, 1973) — costly-to-fake evidence substitutes for direct evaluation. If you lack borrowed prestige, you can stack substitute signals. Toggle them below and watch the beacon.

Drag to rotate. Each signal adds a tier to your credibility beacon — the light grows with total signal.

Right now a hiring manager has nothing to defer to. Every screen becomes a from-scratch evaluation — the hardest path.

Why signals beat resumes

The economics

A hiring manager screening 200 applicants spends ~3 minutes each. Signals are compression: they answer "can I skip verification?"
Costly signals work because they're hard to fake: you can't accidentally have 1,000 users or a merged PR in a serious repo.
Cheap signals (buzzwords, course badges) are ignored precisely because anyone can produce them.

The playbook without prestige

Make work public. One live project with real users beats "5 years experience" text on a page.
Borrow trust laterally. A referral from any engineer the manager rates converts a cold app to a warm one — referred candidates are hired at several times the rate of cold applicants in most company data.
Write one great deep-dive. A single detailed post-mortem or design writeup shows judgment no interview can.

Worked example: two candidates for a startup role. A: ex-FAANG, empty GitHub. B: unknown company, but a devtool with 800 GitHub stars and a writeup of a production incident. Many startup CTOs now interview B first — the signal is more relevant even if less prestigious. Signal quality = credibility × relevance.
