AI WORLD HQPractice for a Job Interview Using ChatGPT as Your Mock Interviewer
Set up a friendly mock interview in minutes, get realistic questions, and simple feedback to sharpen your answers before the real thing.
Hook: By the end of this short session you'll have run through a realistic mock interview, received clear feedback on your answers, and spotted the one or two stories you'll want to polish before the real thing. This guide is for anyone with an interview coming up — first job, new role, or a step up — who wants low-pressure practice that fits inside a coffee break.
💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.
- A free ChatGPT account (or a paid Plus plan if you want faster replies); sign up at chat.openai.com if you haven't already.
- The job ad or a short list of the role's key duties, plus your CV — even a rough one is fine.
- Roughly 20–30 minutes of quiet time, a notebook or open notes app, and the willingness to type your answers out (speaking them aloud afterwards really helps).
Open a fresh chat in ChatGPT
Go to chat.openai.com in your browser, or open the ChatGPT app on your phone, and tap the "New chat" button — usually a pencil icon or a "+" in the top-left of the screen. A blank chat page appears, ready for your first message. A fresh chat means ChatGPT won't be confused by anything you asked it yesterday, so you get a clean interview simulation. If you can't see a new-chat button, look for a circular "+" or your profile menu instead.
You'll know it worked when you see an empty message box with no old conversation history above it.
Ask ChatGPT to act as your mock interviewer
Click into the message box and type a clear setup. A prompt is just the instruction you give an AI — here, we're telling ChatGPT the role and the rules. ChatGPT will reply with a friendly acknowledgement and usually ask which role you'd like to practise for. Be specific about the job title, the seniority, and the kind of questions you want (behavioural, technical, or both). If your screen shows a model picker at the top, any current model works for this.
You'll know it worked when ChatGPT responds in character — addressing you as if the interview has just begun, and asking its first question.
Answer the first question out loud (or on paper)
Read the question, take a breath, and write your answer as if you were speaking it. Real interviews reward stories that follow the STAR pattern — Situation, Task, Action, Result — so structure your reply that way without naming it. Keep each answer to roughly 60–90 seconds when spoken; on the page that's about 4–6 sentences. Don't worry about polish; the goal here is to get something on the screen you can react to. If a question throws you, ask ChatGPT to rephrase it or give you a hint.
You'll know it worked when you've typed a real, specific answer — not a vague one like "I'm a team player."
Ask for feedback before moving on
Reply with one short sentence asking for feedback, then wait. ChatGPT will give you two or three specific notes — usually about clarity, length, missing detail, or what to add. This is the step most people skip, and it's where the real learning happens. Treat the feedback like a coach's notes: read it, nod, and improve the next answer. If the feedback feels too harsh or too vague, ask ChatGPT to be kinder, or to focus on one thing only.
You'll know it worked when ChatGPT returns concrete suggestions (not just "good job") and then asks the next interview question.
Practice the awkward questions on purpose
After two or three standard questions, ask ChatGPT to throw you the hard stuff — the gaps in your CV, the reasons you're leaving, salary expectations, or a tricky behavioural question you've been dreading. The point is to rehearse them in private so they stop being scary. If you want, also ask it to role-play a slightly sceptical hiring manager. ChatGPT cannot truly read your face or body language, so this part is purely about the words you choose.
You'll know it worked when you feel yourself thinking instead of just typing — that's the muscle getting stronger.
Wrap up and save your best answers
When you've had enough, ask ChatGPT to summarise your strongest answers, the gaps it noticed, and three things to work on before the real interview. Copy that summary into your notes. Then scroll back through the chat and copy any answer you liked into a document titled "Interview stories" — you'll reuse these in future applications. Honest limitation: ChatGPT can't tell you whether you'll actually get the job, but it can absolutely sharpen how you talk about your experience.
You'll know it worked when you have a short, readable list you can refer to the night before.
- Mistake: Asking for all questions at once and dumping bullet-point answers. Fix: Insist on one question at a time and write in full sentences — that's what trains you for the real thing.
- Mistake: Treating vague feedback as a pass. Fix: If ChatGPT only says "great answer," reply with "give me two specific things to improve" so it has to be useful.
- Mistake: Skipping the awkward questions. Fix: Practise the scary ones twice — the second time they're no longer scary.
Open a fresh chat, paste this exact prompt, and answer the first question: "Act as a friendly mock interviewer for a [paste the job title here] role. Ask me one question at a time and give brief feedback after each answer. Start with a common opening question."
