Which AI is best for interview preparation?
The best AI for interview preparation depends on what you need. A chat assistant is good for researching the company and drafting answers. A voice interviewer is better for practising saying them, because an interview is spoken.
Most people need both: one to plan what to say, and one to practise saying it out loud.
What kinds of AI help with interviews?
| Kind | Good for | What it misses |
|---|---|---|
| Chat assistant, such as ChatGPT or Gemini | Researching the company, drafting likely questions and answers | You type, so you never hear how your answer sounds |
| Voice interviewer | Answering out loud, follow-up questions, timing | Less useful for deep research |
| Video practice tool | Camera presence, eye contact, posture | Often fixed questions with no follow-up |
| Resume checker | Matching your CV to the job description | Does not prepare you to talk |
How do you choose?
- If you do not know what the company does or what the role needs, start with a chat assistant.
- If you know what to say but freeze or ramble when you say it, use a voice interviewer.
- If the real interview is on video, add one video practice run with your camera on.
- If you say um or like often, pick a tool that counts filler words, so you can see the number drop.
A one week plan using two tools
- Day 1: ask a chat assistant to summarise the company and list ten likely questions for the role.
- Day 2: write short notes, not scripts, for your top five answers.
- Days 3 to 5: do one spoken practice interview a day and read the report after each one.
- Day 6: practise the two answers that scored lowest.
- Day 7: one full run at the time of day your real interview is booked.
Do not memorise an AI written answer word for word. Interviewers notice, and a follow-up question will break it. Use the AI for structure, then say it in your own words.
Where Just One Interview fits
On Just One Interview, you type the role and the skills you want tested, and an AI interviewer asks you the questions out loud. You get a report with a score for each answer and a count of your filler words. It runs in the browser on your phone, and the free plan includes 20 minutes of practice a month. For the chat side, read interview practice with ChatGPT or Gemini.
