A real-time interview assistant handles a technical screen by switching between two kinds of answer. For the conceptual questions that open the round, it shows live captions and a structured spoken-style answer in about 2 seconds. For the coding problem, Coding mode (Ctrl+Shift+C) returns complete code in your language with an example run, and Read screen (Ctrl+Shift+S) captures the problem statement from the shared coding editor. When the interviewer asks a conceptual follow-up mid-problem, the 🗣 Talk answer button (Ctrl+Shift+E) answers that one question in words while Coding stays on. The tool does not type for you or talk for you, so the screen is still yours to carry.
This guide covers what a technical screen contains, how to set the assistant up for each part, and the places where a live outline helps less than plain preparation.
What a first technical screen looks like
A technical screen is the first conversation with an engineer rather than a recruiter. Formats vary by company, but the common shape is:
- Five minutes of introductions. Your background, their team, what the round covers.
- Ten to fifteen minutes of conceptual questions. Language and platform fundamentals, a question or two drawn from your résumé, sometimes a short design sketch.
- Twenty-five to thirty-five minutes on one coding problem. Usually easy to medium, in a shared coding editor, with follow-ups on complexity and edge cases.
- Five minutes for your questions.
Our technical phone screen guide covers the format company by company. The point here is that the round changes mode in the middle, and a live tool has to change with it.
Part 1: conceptual questions in words
Leave Coding mode off for the opening. CoPilot Interview's real-time interview assistant captions each question and shows key points first, then detail. Conceptual questions in a screen tend to be short and factual, so the structured answer arrives before you have finished taking a breath. Example questions (we wrote these as illustrations of the type):
- "What's the difference between a process and a thread?"
- "When would you pick a hash map over a sorted array?"
- "How does your language handle memory, and what does that cost you?"
- "Tell me about the hardest bug on the project at the top of your résumé."
The last type matters: it comes from your résumé, so paste the résumé and job description before the call. The answer then refers to your actual project rather than a generic one. Read the key points, then speak in your own words with your own detail. If the outline runs long for a quick question, press Shorter; if the interviewer asks you to go deeper, press Longer.
Part 2: the coding problem
When the interviewer shares the problem, press Ctrl+Shift+C to turn Coding mode on and pick your language from the picker (50 or more languages are listed). Then:
- Capture the problem. Press Ctrl+Shift+S (Read screen) with the shared coding editor visible. The app reads the statement and any examples and returns complete code with an example run. Pin screen does the same for a chosen area, such as the editor pane alone.
- Choose how the code looks. The 📝 Note option adds a 2-4 line approach and complexity comment at the top, which doubles as your talking points. 🚫 No comments gives clean code if you would rather narrate without comments.
- Type it yourself, and talk while you type. The interviewer is watching the editor. Typing the approach in your own order, naming your own variables and explaining each step is what the screen is assessing.
- Debug from the screen. If a test fails, press Ctrl+Shift+D for 🐞 Debug mode and Read screen again; it finds bugs in the code captured from the editor.
Press Ctrl+Shift+F for click-safe mode so the app window never takes focus from the editor while you work. Every hotkey works while your cursor stays in the editor, which is the whole reason hotkeys exist. The coding interview copilot page covers these options in more depth.
Part 3: conceptual follow-ups during the problem
The hard moment in a technical screen is the question that arrives while you are mid-code: "Why a set and not a list?" or "What's the complexity of that loop?" If Coding mode is on, the default answer would be more code. Press Ctrl+Shift+E (🗣 Talk answer) and the next question is answered in words, once, while Coding stays on for whatever comes after. The table below maps the round's moments to the right setting.
| Moment in the screen | Setting | Hotkey | What you get |
|---|---|---|---|
| Opening conceptual questions | Coding off | Ctrl+Shift+L to listen | Captions plus a structured spoken-style answer |
| Problem appears in the shared editor | Coding on, Read screen | Ctrl+Shift+C, then Ctrl+Shift+S | Complete code in your language with an example run |
| "Why did you choose that structure?" mid-problem | Talk answer, one question | Ctrl+Shift+E | A short answer in words; Coding stays on |
| A test case fails | Debug on, Read screen | Ctrl+Shift+D, then Ctrl+Shift+S | The bug in the captured code and a fix |
| "How would you scale this?" at the end | Coding off or Talk answer | Ctrl+Shift+C or Ctrl+Shift+E | Trade-offs in words rather than more code |
| Window is covering the editor | Hide or scroll | Ctrl+Shift+H, Ctrl+Shift+/ | Window hidden or the answer scrolled without clicking |
If you forget to press Talk answer and get code back for a conceptual question, press Ctrl+Shift+R to redo after switching, or just answer from what you know. Reading a wrong-shaped answer is worse than a plain "let me think" and a sentence of your own.
What the tool does not do in a technical screen
It does not type into the shared editor, and it does not speak. If you paste code you cannot explain, the first follow-up exposes it; if you read an outline word for word, your voice goes flat and the interviewer notices. The useful version of a live tool here is narrower: it catches a question you half heard, reminds you of the complexity you knew but could not retrieve under pressure, and gives you a reference implementation to compare against your own while you debug.
It also cannot help with the part of the screen that is simply you: how you react to a hint, whether you test your code before declaring it done, whether you ask about input size before choosing an approach. Our guide on live coding interview tips for Zoom and Teams is about those habits.
Prepare the way the screen will test you
Run the free AI mock interview with the job posting. It builds a mix of conceptual and coding questions from the posting and your résumé, reads each aloud, and scores your spoken answer out of 10 with what worked and a model answer. Do the conceptual questions out loud and the coding question by actually writing code, then explain it aloud as if the interviewer were watching. The 📊 Summary report afterward lists areas to improve with a drill each; for most people the weak spots are complexity analysis and edge cases, both of which are cheap to fix with a week of drills.
The free AI interview assistant plan gives 15 minutes a day in sessions up to 15 minutes, with no signup, which covers daily practice. A full 45- to 60-minute screen needs Standard (sessions up to 60 minutes) or Pro (70-minute sessions). If you compare AI interview assistants for technical screens, test the one thing that matters most: can it switch from code to words for a single question and back without you leaving the editor?
Follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan.

How does the assistant know whether to answer in code or in words?
You tell it. With Coding mode off, every question gets a spoken-style answer. With Coding mode on, questions get complete code. Press Ctrl+Shift+E (Talk answer) to have the next single question answered in words while Coding stays on.
Can it read the problem from the shared coding editor?
Yes. Press Ctrl+Shift+S (Read screen) while the editor is visible and it captures the problem statement and examples, then returns code with an example run. Pin screen captures a chosen area, such as the editor pane, and answers what is shown there.
Does the assistant type into the editor for me?
No. It shows code in its own desktop window on your screen, and you type what you understand into the editor. Typing and explaining the approach yourself is the part of the screen the interviewer is scoring.
What if I get code back for a conceptual question?
Press Ctrl+Shift+E for Talk answer and then Ctrl+Shift+R to redo, or simply answer from your own knowledge. A plain sentence of your own is better than reading a mismatched answer.
Which programming languages does Coding mode support?
The language picker lists 50 or more programming languages. Pick the one you will use in the shared editor before the problem starts so the code and the example run match what the interviewer expects.
How long a session do I need for a technical screen?
Most technical screens run 45 to 60 minutes. The free plan allows sessions of up to 15 minutes, so a full screen needs Standard, which allows 60-minute sessions, or Pro with 70-minute sessions. Hour packs from $5.99 also work and never expire.
