5 skills, each taught in a guided lesson and then practiced out loud with the coach.

3 h 50 min total5 lessons10 practices

  1. Explaining LLM basics clearly

    Skill 1, 45 min, 3 sessions

    You will meet with a coach to practice translating complex technical terms into simple analogies. You will practice explaining how smart text systems process words, recall information, and control their creativity.

    • Lesson

      Simplify how language models work

      15 min
    • Practice

      Explain core text generation concepts

      15 min

      Tim asks you to explain tokens, context windows and temperature as if to a teammate. He checks that you use plain language and a good analogy before adding technical detail.

    • Practice

      Compare model customization methods

      15 min

      You compare prompting, retrieval and fine-tuning for a given use case. Tim listens for when you would choose each one and whether you mention cost, data needs and maintenance.

  2. RAG system design

    Skill 2, 45 min, 3 sessions

    You will meet with a coach to break down how to explain search-based AI systems in an interview. You will practice structuring your thoughts around data preparation, search logic, and quality checks.

    • Lesson

      Map out your system design strategy

      15 min
    • Practice

      Explain the data pipeline out loud

      15 min

      You walk Tim through a RAG pipeline from document ingestion and chunking to retrieval and the final prompt. He probes each stage and checks that your choices are justified.

    • Practice

      Tackle incorrect answers and evaluation

      15 min

      Tim describes a RAG system giving wrong or made-up answers and asks how you would find the cause. He checks that you separate retrieval problems from generation problems and describe how you would measure quality.

  3. Agentic AI and tool use

    Skill 3, 45 min, 3 sessions

    You will work with a coach to structure your explanations of how independent AI systems make decisions and use tools. You will outline real-world examples of system failures and safety controls for a project you choose.

    • Lesson

      Prepare your agent interview responses

      15 min
    • Practice

      Practice explaining smart AI behaviors

      15 min

      You explain how an agent plans, chooses tools and uses results to decide its next step. Tim listens for a clear loop description and a concrete example from a real use case.

    • Practice

      Defend your system safety choices

      15 min

      Tim challenges the safeguards on an agent you designed, from tool permissions to human approval steps. He checks that you name realistic failure cases and explain how your controls catch them.

  4. Your AI project story

    Skill 4, 45 min, 3 sessions

    You will work with a guide to outline a past project you built. You will learn to highlight your technical decisions and outline what you would improve in under two minutes.

    • Lesson

      Structure your quick project presentation

      15 min
    • Practice

      Pitch your project and explain choices

      15 min

      You present an AI project you built in under two minutes, then explain the key technical decisions. Tim checks that the problem, your role and the result come through clearly.

    • Practice

      Answer tough questions about your limits

      15 min

      Tim asks what your project does badly, what broke and what you would rebuild. He listens for honest limits, evidence you measured them and a sensible improvement plan.

  5. Live coding and system questions

    Skill 5, 50 min, 3 sessions

    You will meet with your guide to explore strategies for talking through your programming choices. You will practice asking clarifying questions and learning how to handle moments when you do not know the answer.

    • Lesson

      20 min
    • Practice

      Clarify requirements and think aloud

      15 min

      Tim gives you an open coding or design problem and you ask questions before starting. He checks that you confirm inputs and constraints, then narrate your approach as you work.

    • Practice

      Solve problems when you get stuck

      15 min

      Tim hands you a problem where you are likely to hit a wall. He checks that you say what you are trying, test a simpler case and keep reasoning out loud instead of going quiet.

How it works

How practice works with the AI coach

Creatium Coach is a live AI voice coach. You do not watch videos or fill in quizzes: you talk, it listens, and it answers like the real person would.

  1. Learn it with a guide

    Each skill opens with a guided lesson. The coach explains the idea, asks you questions and checks you have it before you move on.

  2. Practice it out loud

    In each practice the coach plays the other side: the interviewer, the customer, the buyer or your team. You answer in your own words, by voice.

  3. Get one thing to fix

    After every answer you hear what worked and the one change that would make it stronger, then you try again until it sounds right.

  4. Make it yours

    Tell the coach your role, your company or your situation and it reshapes the plan around your goal. The ready-made goal is just the start.

FAQ

Questions about ai engineer interview questions

How do I prepare for an AI engineer interview?

Cover four areas: LLM fundamentals such as tokens, context windows, embeddings and sampling settings; system design for RAG and agent-based applications; evaluation and failure handling; and at least one project you can explain in depth. Practice explaining each topic simply first, then add detail when asked, since interviewers often probe with follow-ups. Be ready to discuss trade-offs like cost, latency and accuracy. This plan lets you rehearse each area out loud with Tim playing a senior engineer who asks those follow-ups.

What is the difference between agentic AI and generative AI?

Generative AI refers to models that create content such as text, images or code in response to a prompt. Agentic AI uses such models as part of a system that can plan steps, call tools or APIs, observe results and decide what to do next toward a goal, often over several turns. In short, a generative model produces an output, while an agent takes actions and loops until a task is done. The agentic AI session in this plan has you explain this distinction and defend the safety controls you would put around an agent.

What RAG interview questions are asked for experienced roles?

Experienced candidates are often asked how they would chunk and index documents, choose embedding models, combine keyword and vector search, rerank results, and handle questions the knowledge base cannot answer. Expect questions about evaluating retrieval and answer quality, reducing hallucinations, keeping indexes fresh, and controlling cost and latency. Interviewers usually want trade-offs from real projects rather than textbook definitions. The RAG system design session in this plan has you walk Tim through a pipeline and handle his questions on wrong answers and evaluation.
