When you stop thinking about vibe coding and start thinking about assisted coding work, you see the AI Agent Coding Assistant as a pair programming exercise.
You have to be clear in the communication about what to do, iterate slowly, and review everything.
Do you use AI Agents for coding at work?

From a CTO at a startup:
"We interview devs by giving them a task to build an app on the spot, from scratch (2x BE endpoints, some frontend.) They can use AI, ofc - and we dig into why they did this or that.
What is surprising: 14/15 devs from Meta failed this screening."
