An AI interview simulator runs a practice interview for you: it asks questions out loud, listens to your spoken answers and scores each one, so you can rehearse a full round on your own schedule. In CoPilot Interview, the simulator is Mock Interview mode in the free desktop app: it builds the round from your résumé and the job description, scores every answer out of 10 with what to fix and a model answer, and ends with a report card.
If you only want to try a few questions with nothing to install, the browser AI mock interview has 113 real questions across 9 tracks. This page walks through one simulated session from setup to report card, so you know what to choose and what to do with the results.
What an AI interview simulator does that a question list doesn't
A question list gives you prompts. A chatbot can ask you questions if you write the right prompt (our ChatGPT mock interview prompts show how). A simulator runs the whole loop for you: question, spoken answer, score and notes, next question, then a summary of the round.
That loop matters because interviews test how you answer out loud with someone waiting, not whether you recognize a good answer when you read one. Saying an answer exposes the habits that reading hides: a long wind-up, no clear ending, a result you forgot to mention.
It also matches how many employers interview. The U.S. Office of Personnel Management describes the most structured interviews as asking every applicant the same predefined lead and follow-up questions and scoring answers against benchmarks of proficiency (OPM on structured interviews, checked October 2026). A simulator with a fixed question set and a consistent score gets you used to that format. It is a practice stand-in, not a copy of any employer's scale.
Step 1: set up the simulated interview
Start by pasting your résumé and the job description. Mock Interview draws its questions from both, so the round names the kind of work in the posting instead of generic prompts. Then choose five settings:
| Setting | Options | How to choose (our suggestion) |
|---|---|---|
| Level | The level of the role | Match the job posting, not your current title. If the posting is a step up, practice at that level. |
| Number of questions | 3, 5 or 8 | 3 for a warm-up or a 15-minute free session; 5 for a normal practice round; 8 to rehearse the stamina of a long loop. |
| Mix | Behavioral, technical, system design, coding | Mirror the round you are preparing for. A recruiter screen is mostly behavioral; an onsite loop often mixes all four. |
| Coding language | Your chosen language | The language you will actually use in the interview, even if you know another one better. |
| Focus (optional) | A topic you type in | A technology named in the posting, a weak area such as system design trade-offs, or a theme like leadership stories. |
Example setup (we wrote this to show the choices; it isn't from a real user): a mid-level backend posting that mentions Go and payment systems. Level: mid-level. Questions: 5. Mix: behavioral, system design and coding. Language: Go. Focus: payment reliability and retries.
If you don't have a target job yet, paste a posting you would apply to. Our guide to a mock interview from a job description explains which parts of a posting matter most, and the interview questions from a job description tool lets you preview likely questions first.
Step 2: answer out loud, one question at a time
Once the round starts, it runs like a call with a patient interviewer:
- The question is read aloud. Listen the way you would on a real call, rather than reading ahead.
- You speak your answer. Answer as you would to a person: open with the direct answer, then the detail.
- Coding questions wait for you. They never auto-submit, so you can think in silence, then work through your solution in your chosen language and explain it.
- The answer is scored. You get a score out of 10, what to fix and a model answer before you move on.
- The next question starts. The round continues until you reach the number of questions you chose.
Small details make the simulation closer to the real thing. Use the headset and room you'll use on the day. Keep notes closed. Give yourself a time box for each answer, roughly what a real interviewer would allow, and stop when you reach it.
Step 3: read the score and the report card
Each spoken answer gets a score out of 10, a note on what to fix and a model answer. After the last question you get a report card for the round. Read it in this order:
- The lowest score first. That is where one change gains the most.
- The fix note before the model answer. The note tells you what was wrong; the model answer shows one way it could look when it's right.
- Patterns across question types. If every behavioral answer loses points for the same reason, that one habit is your next practice goal.
Example notes from one round (we wrote these to show how to read results; they are not output from the app):
- Behavioral, 6/10: the story was clear, but the result had no number and no outcome anyone could check.
- System design, 5/10: jumped straight into the database without stating requirements or expected traffic.
- Coding, 8/10: correct and well explained; complexity stated. Move on.
In that example, the next round should repeat behavioral and system design questions, not coding. For worked examples of each part of the feedback, see AI interview feedback: what it looks like, and for what the numbers do and don't tell you, read what a score out of 10 means.
Desktop simulator vs the browser version
CoPilot Interview offers the simulator in two places. They suit different moments.
| Desktop Mock Interview | Browser AI mock interview | |
|---|---|---|
| Install | Desktop app for Windows 10+ and macOS 12+; no signup needed to start | Nothing to install |
| Where questions come from | Built from your résumé and the job description | 113 real questions |
| Question types | Behavioral, technical, system design, coding, in the mix you choose | 9 tracks: behavioral, system design, coding, data science/ML, frontend, DevOps, SQL, product, security |
| Round length | 3, 5 or 8 questions | You pick questions from the bank |
| Results | Score out of 10 per answer, what to fix, model answer, then a report card | See the browser mock interview page |
| Best for | Rehearsing for a specific job | Trying a track quickly, or practicing on a computer where you can't install apps |
On the free plan the desktop simulator gives you 15 minutes every day, with sessions up to 15 minutes, all four modes and the free AI models; no credit card is needed, and it isn't a trial. Standard ($14.99/mo on sale; regular $19.99) adds 60-minute sessions, up to 100 minutes a day, with no gap between sessions. See pricing for Pro and Pro+.
Limits of any AI interview simulator
A simulator is good at volume and structure. It is weaker at a few things you should cover another way:
- It grades what you said, not how you came across. Eye contact, pace and energy on camera need a recording or a person.
- Generated follow-ups aren't a person's curveballs. Before an important loop, do at least one session with a friend, mentor or coach. Our guide to mock interview practice without a partner has ways to raise the pressure on your own.
- Model answers aren't your experience. Borrow the structure, never the story. See how to use AI interview answers in your own words.
- Scores move a little. React to the pattern across several answers, not to one point up or down.
If your real interview is an AI interviewer, a one-way recorded video interview or an online assessment, a simulator is the right preparation. Take the assessment yourself and follow the employer's rules — use CoPilot Interview to practice beforehand.
The same app also has Candidate Mode for live help in real calls on Zoom, Microsoft Teams and Google Meet. Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan. For more practice formats, see the behavioral mock interview and system design mock interview guides.
