The browser demo at copilotinterview.com/try lets you practice one interview question at a time with nothing to install and no signup. Pick one of 145 questions across 10 tracks, type your answer, and the AI grades it with a score out of 10, strengths, areas to improve and what an interviewer might ask next. It's a sample of the desktop app's Mock Interview, which runs a full round from your résumé and grades spoken answers.
CoPilot Interview is an AI interview assistant for Windows and Mac. The demo is the no-install way in, and it also works where there's no desktop app, such as Linux and Chromebooks.

Filter the Question bank by Category and by Difficulty (Easy, Medium, Hard), or search it. Some coding questions hand you a buggy snippet to debug, and the Visual / Charts questions show a chart to read and talk through.
How a practice question works
- Open /try and pick a question. The arrow keys and Enter work too, and Esc goes back to the list.
- The AI interviewer reads the question aloud. You can mute the voice, and CC on shows captions.
- A countdown starts. Each question has its own limit, from two to ten minutes, and your answer is submitted automatically when it reaches zero.
- Type your answer in the box. The page doesn't record your voice, so say the answer aloud first if you want speaking practice, then type the key points. Some coding questions offer Need a hint?.
- Optional: Attach screenshot (PNG, JPEG or WebP, up to 4 MB). The page says your screenshot is sent to the AI for grading only and isn't stored on the company's servers.
- Click Submit answer → or press Ctrl + Enter.
- Read the feedback, then choose Try this again ↻ or Pick another question →.
What the feedback shows
- A score out of 10.
- 🟢 Strengths: what your answer did well.
- 🔴 Areas to improve: what was missing or weak.
- 🔎 What an interviewer might ask next: the likely follow-up question.
The demo doesn't show a model answer. The desktop Mock Interview does, along with the rubric points you missed.
