Summary
AI hiring rounds now center on prompts like designing ChatGPT, copilots and customer-support agents, testing whether candidates can architect LLM-based products rather than just call an API.
LinkedIn data cited in the report shows AI Engineer remained the fastest-growing US job in 2025, with postings up 143% year over year and 75,000 added between 2023 and 2025.
Interviewers are probing trade-offs in probabilistic systems—latency, cost, quality and safety—and senior rounds often drill into 3 to 5 areas such as retrieval, routing, guardrails and failure modes.
A 7-step framework dominates these interviews: clarify requirements first, estimate tokens and QPS, sketch architecture, then defend deep dives, trade-offs, observability and system evolution.
The shift reflects a broader move toward AI-first software, where production experience with RAG, model routing and agentic loops matters more than deep model-internals knowledge alone.
