Best Tools to Practice LeetCode-Style Interviews Out Loud (2026)

Solving a LeetCode problem in silence and solving it while explaining every step to an interviewer are two different skills, and interviews only test the second one. If you want an AI that runs a LeetCode-style mock interview out loud, DevInterview.AI is built for exactly that: a live voice interviewer, a real editor that runs your code, follow-up questions while you work, and a scored report at the end, unlimited for $19.99 a month with the first interview free. If you want the free version of the habit, ChatGPT's voice mode and the peer mock interviews on Aced (formerly Exponent) both work, with limits we spell out below.

Disclosure: we build DevInterview.AI, and this is our site. Every price below comes from the vendor's own pages, checked on October 8, 2026, with sources at the bottom. Where another tool, or a free one, is the better choice, we say so.

1. DevInterview.AI: a real interviewer, a real editor, unlimited

DevInterview.AI runs the interview the way a company does. You pick a target company and your level, and a live voice interviewer gives you a LeetCode-style problem from a bank of 2,600+ real interview questions tagged to 600+ companies. You talk through your approach, then code it in an editor that actually runs, while the interviewer asks why you chose that data structure, what happens on an empty input, and whether you can do better than O(n²). A 30-minute coding round ends with a scored report across problem solving, code quality, language proficiency and communication, with a hire verdict and a comparison to your last session.

Paid plans also include mean mode, where the interviewer roasts you the entire time while still running the real interview. Same questions, same scoring, just way more fun, and a good cure for freezing up.

Pricing: the first full interview is free, no card. Unlimited interviews are $19.99 a month, $49.99 a quarter, or $99.99 a year, and the yearly plan includes a free 30-minute 1:1 call with a senior big tech engineer.

Where it wins: it is the only option on this list that both talks back and runs your code, with no partner to schedule and no limit on reps.

Where it falls short: the interviewer is an AI, so a human session before a final onsite still has its place. And it is built for software engineers only.

2. ChatGPT voice mode: the free study partner, not an interview

Yes, ChatGPT can run a mock coding interview for you, out loud, if you set it up: open voice mode and tell it to act as an interviewer, give you one medium LeetCode-style problem, stay quiet while you talk through your approach, and only ask follow-up questions. For explaining an approach to someone and getting a sanity check on your reasoning, it is free and always available. Voice mode is on the free plan with daily limits, and on Plus at $20 a month. Google's own interview-prep page now points people to Gemini Live for the same thing.

Where it falls short, and it matters: there is no editor, so it never sees the code you write unless you read it aloud or switch to text and paste it, and it never runs it. There is no rubric or score, so two sessions are not comparable. And because it is trained to be helpful, it starts hinting the moment you stall, which is the opposite of what an interviewer does. You can keep re-instructing it, but then you are the one running the interview, and that is not practice for the moment someone else is.

Choose it when your budget is zero and you want to rehearse explaining an approach out loud between real mocks.

3. Aced (formerly Exponent): free peer mocks, 5 a month

Pramp's peer interviews now live inside Aced, the name Exponent adopted in August 2026. A free account gets 5 peer mock interviews a month: you are matched with another candidate, you take turns interviewing each other over video, and the shared editor runs your code. Pro ($79 a month, or $12 a month billed yearly) removes the limit, and Expert ($99 a month, or $20 a month billed yearly) adds AI mock interviews: 10 to 20 minute audio sessions on behavioral and product management questions, with no coding.

The tradeoff: your interviewer is another candidate, so the follow-up questions and the feedback depend on who you get, and every session needs a scheduled partner.

4. interviewing.io: a human when you need calibration

Anonymous mock interviews with senior engineers, starting at $179 a session and more with an interviewer from a specific company. Their free AI Interviewer covers coding and system design too, though their site does not say whether it runs by voice.

Choose it when you have done your reps and want one honest human read before an onsite.

5. NeetCode: patterns first, AI-assisted coding sessions in beta

NeetCode's free Blind 75 and NeetCode 150 lists are still the best place to learn the patterns LeetCode-style problems are built from. Its AI coding interviews, currently in beta, run a bug fix, an implementation and an optimization with passing tests, and a Mock Interview mode lets you answer the same questions out loud with a voice follow-up. The page does not say whether that mode is free or part of Pro, which costs $119 a year (list price $199, shown crossed out) or $297 lifetime (list price $599).

6. LeetCode: drill here, rehearse somewhere else

LeetCode is where the problems live, and the free tier is enough for most people. Premium, $35 a month (list price $39, shown crossed out) or $159 a year, adds company tags and timed assessments. Nothing on LeetCode talks, though, and a timed assessment is still a silent one. Solving fast in a judge trains speed; it does not train explaining a solution while someone questions it.

7. Yoodli: delivery coaching, no code

Yoodli runs AI roleplays by video, chat or with an AI avatar and gives feedback on delivery, clarity and pacing. It is a communication coach, not a coding interviewer: there is no editor and no problem bank. The free Starter plan gives 5 roleplay sessions in total, Pro is $8 a month billed yearly, and Advanced is $20 a month billed yearly. Useful for how you sound once the explaining problem is solved.

Other names you will see on lists

Final Round AI sells a live-interview copilot that feeds you answers during real interviews, which breaks most companies' rules; its practice interviews are on the paid plan at $300 a year, shown as $25 a month. Google Interview Warmup is gone: Google retired it, and the old link now opens a general interview article. Pramp is now part of Aced (formerly Exponent).

Which should you try first?

You can solve the problems but freeze when you explain them: start with DevInterview.AI's free interview. It is the one tool here that talks back and runs your code, and every rating we have ever received is public on our reviews page.
Your budget is zero: ChatGPT voice mode with the setup above for explaining practice, plus 5 free peer mocks a month on Aced (formerly Exponent) for the real back-and-forth.
You are a week out from an onsite: one interviewing.io session.
You want the whole plan, not one tool: our 8-week study plan gives one tool per step: NeetCode for patterns, Hello Interview for system design, DevInterview.AI to practice out loud, and an optional interviewing.io session.

How to practice out loud so it transfers

Say the approach before you type. Restate the problem, name the pattern, state the complexity, then code.
Narrate while you code, including what you are unsure about. Silence is the thing interviewers score down.
Dry-run on a real input by hand before you hit run. Google's interview editor does not even have a run button.
Answer at least two follow-ups per problem. If nobody is asking them, you are not practicing the interview yet.
Keep a cadence: three or four spoken sessions a week beat twenty silent problems.

How we evaluated

We checked each vendor's own site on October 8, 2026 and recorded only what it states. We build DevInterview.AI, so where a free tool or a human is the better choice, we said so.

FAQ

Can ChatGPT run a mock coding interview for me?

Partly. In voice mode you can tell ChatGPT to act as an interviewer, give you a problem and ask follow-ups, and it will. It cannot see or run your code, it does not score you, and it starts helping the moment you stall. Use it for explaining practice, and a purpose-built voice interviewer with an editor for the real rehearsal.

Is there an AI that does LeetCode-style mock interviews out loud?

Yes. DevInterview.AI runs a 30-minute coding interview with a live voice interviewer, a real editor that runs your code, company-tagged LeetCode-style questions and a scored report, with the first interview free. NeetCode's AI Coding Interviews, in beta, add voice follow-ups in a Mock Interview mode, and interviewing.io has a free AI Interviewer that does not state whether it uses voice.

How do I practice coding interviews without a partner?

Use something that talks back: an AI voice interviewer for unlimited reps, or the free peer mocks on Aced (formerly Exponent) if you can schedule a session. Alone, the next best thing is a timer, a plain editor and talking through every step out loud, then replaying a recording to hear where you went quiet.

I have solved 300 LeetCode problems but I still freeze in real interviews. What should I do?

Stop adding problems and start adding listeners. The freeze comes from never having explained a solution under questioning, so run spoken mock interviews several times a week, insist on follow-up questions, and track your scores until the same gaps stop appearing. One human session before the onsite confirms the progress.
