Permanent. Your access opens immediately after enrollment, and everything added through 2026 (new modules, updated interview questions, new industry-trend analysis) stays viewable forever.

Yes. The course starts from LLM fundamentals and is beginner-friendly, but basic Python / deep learning is recommended. After enrolling you'll receive a 'pre-course guide' to align your starting point.

After enrolling, a dedicated coordinator will set you up to book two résumé sessions (30 min each) plus one mock interview (60 min + detailed feedback); slots are flexible.

Yes. If you have concerns after enrolling, message the Xiaohongshu support team — refunds are processed with no questions asked.

Most market courses just 'organize knowledge points,' but interviewers test 'decision ability' — why do it this way, and what's the trade-off. Our course focuses on the 'why' and real decision-making, paired with 1v1 résumé and mock interviews — something free materials and most courses can't offer.

Eight recurring categories: Transformer & Attention internals, RAG, Agents & tool calling, LoRA/QLoRA fine-tuning, inference optimization (KV Cache / vLLM / FlashAttention), evaluation & alignment, engineering (data handling, deployment, monitoring), and algorithms & code. The Full-Stack Program's 200+ in-depth explanations cover them all.

Start from the course's guided end-to-end projects: the Full-Stack Program includes four complete projects — a RAG knowledge base, Agent orchestration, model fine-tuning, and inference optimization — each letting you explain the choices and trade-offs. Interviewers value the decision-making of 'why you did it that way' far more than company names on a résumé.

DM 「兔老板工作室」 on Xiaohongshu and reply 「资料」 for a free selected real-question PDF — no quotas, no strings attached; enrolling in the Full-Stack Program adds 200+ in-depth explanations and full project templates. Free materials don't include the deep dives or 1v1 service.
