7 min read The ML platform interview question that trips up strong modelers is how you build training data without leaking the future, and how you serve the same feature online. Read article
7 min read MCP interviews at AI-tooling teams spend less time on wiring a tool server and more on the trust boundaries around tool descriptions, transports, and per-user auth. Read article

8 min read Prompt injection sits at the top of the OWASP LLM list because there’s no complete fix, and interviews for AI-security roles are built around what you actually do about that. Read article
