interview-prep-mcp

This repo is archived. Its Investment Banking questions now ship in ai-interview-questions-mcp (v1.1.0 and later), which has all 200 questions, the same tools, and a Streamable HTTP mode. Use that package instead.

An MCP server with 200 interview questions and model answers for two tracks:

• AI engineer (100): LLM fundamentals, prompting, RAG, agents and tool use, fine-tuning, evaluation, production, system design, coding

• Investment banking (100): accounting, valuation, M&A, LBO, restructuring and current events

Search, browse by topic and level, run mock-interview practice with hidden answers, and get a free self-check link for many questions. Works offline: the question bank ships inside the package (data/questions.json). No API key, no account, no network calls at runtime.

Content comes from two free public question banks:

• https://johnnnmai.github.io/ai-engineer-interview-questions/

• https://johnnnmai.github.io/investment-banking-interview-questions/

Tools

All tools are read-only.

Refreshing the data

npm run build:data

This re-reads the two public sites and rewrites data/questions.json. It is the only step that uses the network.
