SDE → AI is a free interview-prep resource for experienced software engineers who want to move into AI roles.

Most SDEs do not need to start from zero. If you have designed distributed systems, handled scale, debugged production issues, and made tradeoffs under ambiguity, you already have many of the instincts AI engineering interviews test.

The hard part is translation.

A Senior or Staff system design answer might talk about queues, caches, retries, reliability, and ownership. An AI engineering answer often tests the same muscles through RAG, eval pipelines, latency, cost, hallucination control, model serving, and AI infrastructure.

This site starts with free Senior & Staff system design prep because that is the foundation. From there, it expands into AI system design, RAG interviews, LLM app architecture, evals, agents, and practical job-prep resources for SDEs moving into AI.

Everything here is free to start, with no login required. Future tools may include answer feedback, practice workflows, and AI interview-prep experiments — but the core learning path will stay open.
