Cover Letters Are Dead

“Nobody reads them anymore”
VERDICT: Mostly false today - but AI is making it truer every year

Tailored cover letters still win callbacks

Callback rates across 7,287 real job applications
0%5%10%15%20%Callback rate10.7%No cover letter12.5%Generic letter16.4%Tailored letter
A tailored letter lifted callbacks 53% vs. sending nothing. A generic one? Barely moved the needle.

Who's telling the truth about read rates?

Companies that sell cover-letter tools say 83-87% read them. The neutral source - recruiting software - says only ~26% care. The truth lives in between.

The plot twist: AI is killing the signal

Tailoring → callback correlation−51%Tailoring → job offer correlation−79%Decline in signal value after the AI cover-letter tool launched
When everyone's letter is perfectly tailored by AI, tailoring stops meaning anything. Employers are already shifting their trust to work history.

The #OpenToWork Banner Hurts You

“It's the biggest red flag” - ex-Google recruiter
VERDICT: Mostly false in this market - the signal flipped positive after the layoffs

The signal flipped with the market

ChatGPT Does What Resume Tools Do - For Free

“Why pay $50/month for a fancy prompt?”
VERDICT: Partially true - it covers the highest-value 70%, not the whole stack

AI writing help measurably gets people hired

Your Resume Has to Be One Page

“Anything longer gets cut”
VERDICT: False as a universal rule - the data runs the other way, and no ATS cuts page two

Recruiters preferred two pages at every level

The “7 seconds” myth vs. how long reviews actually take

The famous eye-tracking stat measures the first skim - not the real review
The viral stat: initial skim (Ladders eye-tracking)7.4 secActual review: one-page resume (ResumeGo timed)2:24 minActual review: two-page resume (ResumeGo timed)4:05 min
7.4 seconds is triage, not judgment (and it came from a ~30-recruiter panel). In timed simulations, reviewers spent MORE time on two-pagers - the extra page earned attention, not the trash bin.

You Can't Measure Career-Services Impact

“...in any way that satisfies a provost”
VERDICT: Half true - causation is genuinely hard, but provost-grade metrics absolutely exist

Career services users get more offers

Avg. job offers at graduation - NACE 2022 Student Survey (15,860 students, controlled for demographics)
0.000.380.751.121.50Avg. job offers at graduation1.00Used nocareer services1.24Used 1+career service
+24% more offers for students who used even one service - and each additional service added more. Correlational, but controlled.

The skeptic's best point: low reach

Internship search help25.6%Networking prep21.1%Mock interviews20.8%% of graduating seniors who used the service
The most impactful services reach ~1 in 5 students. A service touching 20% of the class can't singlehandedly move institution-wide outcomes.
