How to use an interview copilot in a live coding round

To use an interview copilot in a live coding round, first confirm the employer allows it for that round. Then capture the problem by snipping the prompt, read the suggested approach, and type and narrate the solution yourself in the shared editor. The tool supplies structure and a check on complexity. The thinking and the typing stay yours.

Check whether the round allows it

Do this before anything else, because live coding is the round where employers are strictest. Datadog's interviewing guidelines, which we read on 21 October 2026, say not to use AI in live coding interviews or technical assessments unless the company has told you otherwise, and they also describe an AI-assisted coding interview for some engineering roles that candidates are told about in advance. Anthropic's candidate guidance, read the same day, says live interviews are without AI unless they indicate otherwise.

So there are two honest ways to use a copilot with a coding round. In practice, which is allowed everywhere, and in a live round that explicitly permits it. The rest of this guide works for both. For the rules in detail, see Can you use AI in an interview and is using an AI interview copilot cheating.

What a live coding round tests

A live coding round is a problem solved in a shared editor, such as CoderPad or HackerRank, with an interviewer watching and listening. Three things are scored together: whether you reach working code, whether you can explain your reasoning as you go, and how you handle hints and mistakes.

That is why a tool that dumps a finished solution is a poor fit for the round itself. If you read code aloud that you did not reason through, the first follow-up exposes it. The useful help is the kind that keeps you moving while you think: a restatement of the problem, a list of approaches with their costs, edge cases to check, and a complexity answer you can verify.

Set up before the round

Most problems at the live session come from setup, not from the tool. Do these steps on a normal day, not five minutes before the call.

1. Install and sign in. Follow the setup guide for macOS or Windows.
2. Compose your setup. Add your role, the job description and the interview type. Choose the programming language you will code in. URHIRED AI supports 18, and solutions come back in the language you set.
3. Pick the surface. Open Live coding. The other surfaces are Verbal, System design and Project, and each is tuned for its own kind of question.
4. Choose an answer style. Hints nudges without answering. Structured gives an approach, then code, then reasoning. Conversational is shorter. Choose before the clock starts.
5. Preview a screen share. Share a window, not a browser tab, and check that the shared view shows the call and not the copilot window. The overlay is skipped by screen share. It is not guaranteed against dedicated proctoring software, so test what your setup actually shows.

The security page lists what the app captures and what the window does and does not hide.

Step by step in a live coding round

1. Capture the problem

When the interviewer opens the problem, press Cmd/Ctrl+Alt+A and drag over the prompt. The region is captured and sent in one action, over a frozen frame so your cursor does not change. If the prompt is spoken rather than written, the transcript from system audio carries it.

2. Read the approach, then restate it yourself

The answer arrives as an approach in plain English before any code. Read it, then restate the problem and your plan to the interviewer in your own words. This is the first beat of the round and the one practice rarely covers. Ask the clarifying questions a good candidate would: input size, duplicates, empty input, what should happen on invalid values.

3. Compare options before committing

If the problem has an obvious brute force and a better approach, say both. "The simple version is quadratic. A hash map brings it to linear at the cost of extra memory." Interviewers listen for exactly this trade-off, and it is easier to say when the options are already in front of you.

4. Type and narrate

Write the code in the interviewer's editor yourself. Narrate as you write: what each block is for, and why you chose the structure. Do not read the suggested code line by line. If you do not understand a line, do not type it. Use Hints mode to nudge you when you stall rather than to supply a whole function.

5. Test with named cases

Before saying you are done, walk through a small example by hand, then an edge case: empty input, one element, a duplicate, a large value. Say the expected output before you run anything. Catching your own bug is a strong signal.

6. State complexity

Time and space complexity come back with the solution because it is the follow-up that always arrives. Do not just repeat the claim. Derive it aloud from the loops and data structures, so that you can defend it if the interviewer pushes.

How Hints mode changes the dynamic

Hints is the answer style that matches the spirit of a live coding round. It nudges you toward the next step without finishing the thought: a reminder about a data structure, a prompt to consider a boundary condition, a question about the loop invariant. You still produce the idea. That makes it the best style for practice, and where AI is allowed, the best style for the round too, because the reasoning you voice is yours.

What good narration sounds like

A short example makes the target concrete. The problem: given a list of integers and a target, return the indices of two numbers that add to the target. Here is how the first minute might sound.

"Let me restate that. I get an array and a target, and I return two indices whose values sum to the target. Can the same element be used twice? Is there always exactly one answer? Okay. The simple approach checks every pair, which is quadratic. I can do better by storing each value I have seen in a hash map, then checking whether the target minus the current value is already there. That is linear time and linear space. I will start with the map version."

That paragraph takes about twenty seconds. It restates, asks two real questions, names the brute force, names the better approach with its cost, and commits. Everything after it is typing. A suggestion from a copilot can give you the shape of that paragraph, but only you can say it as if you thought of it, which is why practicing it aloud matters.

What to do when you get stuck

Everyone stalls in a live round. The difference is how you stall.

• Say what you know. "I know I need to avoid rescanning the list. I am deciding between a map and sorting."
• Shrink the problem. Work a three-element example by hand, aloud.
• Ask a clarifying question. It buys thinking time and often removes a case.
• Take a hint from the interviewer if offered, and say how it changes your plan.
• In practice, switch to Hints and read only the first nudge, then try again before reading the next.

A stall that is narrated reads as thinking. A silent one reads as being lost, even when the thoughts are identical.

Practice before the real thing

A copilot is most valuable in the week before the interview, when nobody is watching and nothing is at stake. A simple loop:

• Pick a problem you have not memorized and set a 35-minute timer.
• Talk the whole way through, including the dead ends.
• Use Hints when you stall. Note which hints you needed. Those are your gaps.
• Finish with complexity and two edge cases, aloud.
• Next day, redo the problem from scratch without help.

The narration side is covered in live coding mock: narrate under a timer. The free plan includes 15 session minutes a day with no credit card. Scored mock interviews need a paid plan, listed on the pricing page.

Common mistakes

• Typing before restating. You lose the first beat and risk solving the wrong problem.
• Reading code aloud instead of explaining it. It is audible and it collapses on follow-ups.
• Skipping testing. A passing sample is not a test strategy.
• Staying silent while you look at the suggestion. Say what you are thinking, even if it is "I am checking an edge case".
• Opening the tool in a round where it is not allowed. That is the one mistake practice cannot fix.
