Code Red: Humans on review duty
Interviewing Engineers in the AI Era: Lessons from a Year of Rebuilding
Coinbase says robots write the code now, and commenters are having a full-blown identity crisis
TLDR: Coinbase says artificial intelligence now writes over half its software, so it is changing job interviews to test judgment instead of memorized coding tricks. Commenters are split between cheering the end of pointless interview puzzles and grieving that the fun, human part of programming is being handed to bots.
Coinbase just dropped a very 2025 bombshell: more than half its code is now written by artificial intelligence, with humans acting more like editors, referees, and emergency brake-pullers. That has pushed the company to rethink hiring too. Instead of grilling job candidates to write everything from memory in a timed test, Coinbase says it now cares more about whether people can guide AI, spot its mistakes, and make good judgment calls when the machine sounds confident but gets things wrong.
But in the comments, the real story was the mood swing between mourning, mockery, and cautious relief. One of the loudest reactions came from people who feel the soul of software work is being outsourced, with one commenter joking that engineers "gave away the most fun part" to the "clankers". Ouch. Others rolled their eyes at the corporate tone, basically reading the post as "AI era" investor fan fiction dressed up as hiring philosophy. That cynicism was strong.
Still, not everyone was doomposting. Some readers said the current interview system is already a circus of memorization and lucky guesses, so letting candidates use AI could actually be more honest and less performative. Another camp pushed back hard: interviews should still be about how a human thinks, not how well they drive a chatbot. In other words, the community is split between "finally, modernize this nonsense" and "congrats, you just turned engineers into AI babysitters." The jokes were brutal, the skepticism was loud, and the existential dread was very, very online.
Key Points
- •Coinbase says AI-generated code increased from 5.7% of merged code in Q1 2025 to more than 50% in Q4 2025.
- •The company says humans still review all code and that human review has reached roughly 100% without reducing quality or compliance guardrails.
- •The article states that engineers now spend more time writing specs, directing AI, reviewing AI-generated pull requests, and making architectural and risk judgments.
- •Coinbase says this shift exposed a mismatch between its existing interview process and the actual skills needed in an AI-assisted engineering environment.
- •An internal analysis cited in the article found an 84% correlation between two interview rounds, indicating redundancy and weak measurement of the new skills the company wanted to assess.
