Why Share Your Prompts

Your AI conversations are what make you different.

Everyone ships working code now. What separates great engineers is how they direct AI, how they review output, and how they make decisions. Your prompts make that visible — and that's what gets you noticed.

Transparency builds trust

Any developer can show clean code. Sharing the conversation that produced it proves you understand every line — not just that you can paste it.

Your prompts are your portfolio

How you frame problems, review AI output, catch mistakes, and iterate — that's the real skill. Prompts make it visible in a way a GitHub repo never can.

Same insights, no surprises

You receive the exact same process report that companies see. Full transparency — you'll know exactly what's being showcased and can improve from it.

Real examples — here's what your prompts tell companies
Architecture

Create a user authentication service using NextAuth with GitHub and Google providers. Include session typing and a protected route wrapper.

What companies see: You planned the auth architecture upfront — providers, typing, and route protection in a single prompt. That's forethought, not guesswork.

Debugging

The session type isn't propagating to client components — I'm getting null even after signing in. Here's the error...

What companies see: Instead of saying "fix it" — you shared specific error context and diagnosed the root cause. That's how senior engineers debug.

Refactoring

Refactor the data table — extract the sorting logic into a custom hook and move the filter UI into its own component.

What companies see: The AI didn't suggest this. You identified the code smell yourself and proactively separated concerns. That's engineering maturity.

Self-correction

Actually, wrap the whole app in a SessionProvider at the layout level instead of per-page. That should fix the propagation issue.

What companies see: You proposed the fix before the AI did. Independent reasoning is exactly what companies want to see.

We never share your raw prompts. Companies see structured insights mapped to your commits — your process, distilled into a clear, professional profile.

How We Connect You

Straight to technical interviews.
No recruiter screens. No generic challenges.

CodeJack connects you directly with VC-backed companies that have already seen how you work. Your process profile replaces the resume-scan stage — so when a company reaches out, they're already interested in you.

We build your process profile

Your commits and prompts are mapped into a structured profile that shows how you think, debug, and make decisions — not just what you shipped.

03

Companies see your profile

VC-backed companies browsing our platform see your process insights alongside your code. They already know how you work before any interview.

04

Straight to technical interviews

No recruiter screens. No generic coding challenges. Companies who want to move forward take you directly to technical conversations.
