A free chatbot will write you a confident answer that sounds like everyone else's, and an interviewer's first follow-up will expose it. Used differently, it is excellent: give it your real story and ask it to tighten, question and test it. ChatGPT and Claude do this especially well on their free plans, and Gemini and Microsoft Copilot are also capable. Then say the result out loud, which is where our pick, CoPilot Interview, comes in, since it listens and scores; we make it. Here are the prompts, what each free plan suits, and how to test what you end up with. See ChatGPT mock interview prompts and Claude practice prompts.
Do this, not that
| Weak prompt | Better prompt | Why |
|---|---|---|
| Write me an answer to tell me about yourself | Here is my background. Cut it to sixty seconds in my own words, and ask me what is missing | Your facts, your voice |
| Give me a story about leadership | Ask me five questions to help me find a leadership story of my own | A story you can defend |
| Make this sound impressive | Remove every word I would not actually say | Sounds like you |
| What is the best answer? | What would a skeptical interviewer ask next? | Prepares you for follow-ups |
| Is this good? | Score it out of ten, and show me the weakest sentence | Forces criticism |
Notice what the better prompts have in common: you supply the facts and the tool asks, cuts or criticizes. That keeps the answer yours, which is exactly what you will need when the interviewer asks what happened next, who disagreed with you, and why you decided as you did.
Which free chatbot for what
- ChatGPT: versatile, with voice mode for practice, within free limits.
- Claude: strong at careful editing, especially when told to keep every fact.
- Gemini: handy if you use Google's apps and for quick research; check its facts.
- Microsoft Copilot: convenient in Windows and Edge, and a sensible choice if your files are there. Keep confidential work material out.
- Limits change often, so do not rely on any plan staying the same. See CoPilot Interview versus ChatGPT for what a dedicated tool adds.
How to test the result out loud
- Read your answer aloud once. Mark anything you stumble on.
- Replace those words with what you would really say.
- Say it again without the page, and notice what you forget. That is what does not belong to you yet.
- Have someone ask you a follow-up on the part that sounds best.
- If you cannot answer it, the answer needs to change, even if it reads well.
- Record it, and listen back once.
Things to keep out of a chatbot
- Client names, financials and anything under a confidentiality agreement.
- Patient or student information.
- Your full address and phone number. They are not needed.
- Anything your employer's AI policy prohibits.
- Assume that what you type may be stored, and read the settings on training and history.
