How to Practice Coding Questions in CoPilot Interview

To practice coding questions in CoPilot Interview, open the desktop app's 🎧 Mock Interview tab, leave only 💻 Coding on under 🧩 Question mix, choose your 💻 Coding Language and start the round. Each problem arrives with a function signature, one or two examples and the constraints, plus a code box. Talk through your approach, type your solution, and click ✅ Done answering when you're ready: coding answers never submit on their own.

CoPilot Interview is an AI interview assistant for Windows and macOS. Mock Interview, coding questions included, is on the free plan.

Set up a coding round

1. Click the 🎧 Mock Interview tab.
2. Paste the job description into 📋 Company & Job Description and your résumé into 📄 Your Resume. The app asks the AI for problems that are realistic for the role, not obscure puzzles.
3. Under 🧩 Question mix, click 🗣 Behavioral and 🔧 Technical to turn them off, so only 💻 Coding is highlighted. Add 🏗 System Design if your loop has a design round.
4. Choose a 💻 Coding Language: Python (the default), JavaScript (Node.js), TypeScript, Java, C, C++, C#, Go, Rust, Kotlin, Swift, Ruby, PHP, Scala, SQL, or Auto-detect.
5. Set 🎯 Level, and optionally a topic in Focus (optional), such as graphs or SQL joins.
6. Pick 🔢 Questions. Each coding problem is sized for 15 to 20 minutes, so on the free plan's 15-minute sessions, plan on one problem per session.
7. Click 🎧 Start Mock Interview.

Answer a coding question

1. The interviewer reads the problem aloud. Click ⏭ Skip voice to start right away.
2. The code box appears under the question with this hint: “Optional: type or paste your solution here. Your spoken explanation is graded too — talk through the approach as you would on a call.”
3. Talk while you work. The microphone records your explanation, and it counts toward the grade.
4. Take your time. Auto-finish never applies to coding questions, so silence while you think won't submit the answer.
5. Click ✅ Done answering or press Ctrl+Shift+A (⌘+Shift+A on a Mac).
6. Read the feedback, then click ↺ Retry to try again or Next question ▶ to move on.

Explaining while you code is a skill of its own; practicing thinking out loud covers how to build it.

How coding answers are graded

• If you typed code: correctness, complexity, edge cases and readability in your chosen language.
• If you only spoke an approach: the approach, plus what a working solution still needs.
• 💡 A strong answer: correct code in your language plus two lines on complexity. See how to use the model answer.
• ❓ Likely follow-up: what an interviewer would ask next, often a constraint change or an edge case.
• The score is a whole number from 1 to 10, as for every other question type.

Quick coding reps in the browser

The browser demo has a Coding track of 30 questions. Some code questions have a “Need a hint?” button, some hand you a buggy snippet to fix, and you can attach a screenshot of your work for the AI to grade against. You type the answer and get a score out of 10, strengths, weaknesses and a likely follow-up. It's a good warm-up before a full round in the app. The tracks and question types page lists every demo track.

Practice for assessments, then sit them yourself

Online coding assessments and proctored tests forbid outside help, and their rules say so when you start. Use Mock Interview and the demo to prepare for them, and take the real test on your own.

Frequently asked questions

Can I write code during a CoPilot Interview mock interview?

Yes. Coding questions show a code box where you can type or paste a solution. Typing is optional, but your spoken explanation is graded either way.

Does the mock interview run my code?

No. The AI reads your code and grades its correctness, complexity, edge cases and readability, but nothing is compiled or executed. Test tricky cases in your own editor if you want certainty.

Which programming languages can I practice in?

Python, JavaScript (Node.js), TypeScript, Java, C, C++, C#, Go, Rust, Kotlin, Swift, Ruby, PHP, Scala and SQL, or Auto-detect.

Why didn't my coding answer submit when I stopped talking?

Coding questions never auto-finish, so you can think in silence. Click ✅ Done answering or press Ctrl+Shift+A when you're done.
