I Got 47 Recruiter Messages Last Week—Here's What I Learned About My Own Resume

Last Tuesday, I posted a single comment on a GitHub discussion about LLM optimization. By Wednesday morning, my inbox had 12 new recruiter messages. By Friday, I'd hit double digits again. The kicker? None of them had actually read my profile. One wanted me to relocate to the Bay Area for a junior-level position. Another was offering PHP contract work—I haven't touched PHP in production since 2016.

I spent the better part of an afternoon wondering: How did they even find me? The answer, I've come to realize, is less about targeted recruitment and more about industrial-scale data harvesting. My resume exists in some form across multiple job boards, my LinkedIn is public, and apparently my GitHub username has become a searchable commodity. The recruiter machine doesn't see me—it sees keywords that match a database query.

This got me thinking about the real problem hiding behind the spam: what we choose to expose about ourselves, and why it matters.

The Resume as a Data Product

Here's what I understand now that I've been on hiring side myself: your resume isn't just a document. It's a data point in someone else's funnel.

When you upload to job boards, your information gets indexed, parsed, and distributed. Junior recruiters run automated searches for keyword combinations—"React", "AWS", "5 years experience"—and fire off bulk templates. They're not reading. They're matching. The system incentivizes volume, not quality. Someone hitting 50 outreach attempts per day looks more productive than someone actually understanding what you want to do.

The original article calls this the "recruiter spam machine," and it's an apt description. But I think there's something subtler happening here too. It's not malicious—it's structural. The economics of recruitment favor quantity. Decision-makers rarely reach out to candidates directly anymore. Instead, filtered, pre-screened results come from automated systems, and by then the context is already lost.

Why Keywords Alone Can Backfire

I made a mistake on my last resume update. I added "Machine Learning" to my skill set because I'd been working with embeddings in a production system. Within two weeks, I was fielding offers for ML engineering positions that had nothing to do with my actual work. These were academic research roles, deep learning positions, ML Ops jobs—none of which aligned with what I actually wanted to do.

The irony is that adding that keyword didn't help me find better opportunities. It just expanded the pool of recruiters firing off automated messages. I became noise in a noisy system.

What I'm Actually Doing Differently

So, do I shield my resume? Partially. I've become more deliberate about where my resume lives and what information I expose publicly.

I've removed my resume from job boards that I don't actively monitor. I've locked down my LinkedIn visibility to only accept messages from people with real profiles (not agency accounts). Most importantly, I've stopped listing every tool I've ever touched. My resume now reflects the work I actually want to do, not the broadest possible surface area for keyword matching.

What I don't do is try to game the system or hide entirely. The original article suggests a kind of "shielding" where only contact details are protected—that makes sense. But I think the deeper move is being intentional about your public technical narrative.

If you genuinely want a new role, some visibility is necessary. The goal should be quality visibility, not maximum reach.

The Real Question

Here's what bothers me though: the burden shouldn't be on engineers to protect themselves from poorly-run recruitment systems. This is a market failure. Recruiters have no incentive to be selective if their KPIs are based on outreach volume. Job boards have no incentive to reduce spam if they profit from data licensing.

The solution isn't just personal shielding. It's also being willing to take recruiter calls from people who've clearly done their homework, and ignoring the rest with zero guilt. Your time is valuable. Someone who hasn't read your profile doesn't deserve it.

What about you?

How much of your online technical presence are you comfortable with? Are you actively managing your resume visibility, or have you just accepted the spam as background noise?
