AI mock interview tools, compared
Eight tools for rehearsing a job interview before the real one: what the AI actually does, whether it follows up on your answers, what is free and what it costs — so you can pick the one that fits the interview you have coming up.
Prices and features checked on
We make Colloqa, one of the tools on this page. To keep the comparison useful anyway, every price and free plan below was taken from the tool’s own website on the date above, every tool gets its strengths as well as its limits, and where another tool is the better pick, we say so.

Prices are in US dollars as each tool lists them, before tax, and they change — some tools also show different prices to different visitors. "Follow-up questions" means the next question depends on what you just said; "Yes" is what the tool’s own site says, and "Not stated" means its site doesn’t say.
How we compared them
A mock interview is only worth doing if it is uncomfortable in the same places the real one will be. So we looked at five things, all taken from each tool’s own website:
- Does it follow up? Real interviewers dig into the weak part of your answer. A tool that reads the next question off a list cannot.
- Can you say it out loud? Typing an answer and saying one are different skills, and only one of them happens in the interview.
- Is it built around your interview? Your role, your level and ideally the job posting — not only a generic question bank.
- What do you get afterwards? Specific notes on what to fix, not only a score.
- What does it cost to find out? What is free, whether it needs an account or a card, and the price once you need more.
Tools where an AI interviews you
You talk (or type), an AI plays the interviewer, and you get feedback at the end. They differ most in whether it feels like a conversation or a quiz, and in how much you can do for free.
ColloqaOur tool
- Practice by
- Voice, text
- Free
- 1 full interview a day, up to 45 min of voice; account needed, no card
- Paid
- $8.99/week · $19.99/month
An AI interviewer runs a spoken (or typed) interview built from your role, your level and, if you paste it, the job posting. It follows up on what you actually said, and an animated interviewer speaks each question out loud, so it feels like a call rather than a form.
Afterwards you get written feedback — what worked, what fell apart, the one thing to work on next — and a skill profile scored on eight axes that is tracked from session to session. Each weak spot can be turned into a short drill.
It runs in 12 languages, including Ukrainian, Polish, Korean and Japanese, in the browser on a phone or computer. The same tool also covers salary negotiations, difficult conversations and interviewing a candidate as the hiring manager.
Where it falls short: No video or body-language analysis, no human coaches and no live coding environment, and it is newer than most tools here, so there is no question bank or course library. The free plan is 1 interview a day; drills and unlimited sessions need a subscription ($8.99/week or $19.99/month, 7-day money-back guarantee).
Best for: A realistic spoken interview built from the job you applied for — in your own language
Yoodli
- Practice by
- Voice, video (on camera)
- Free
- 5 roleplays in total; account needed, no card
- Paid
- $11/month · $8/month (billed yearly)
Yoodli puts you in a video-call style roleplay: you are on camera, an AI persona plays the interviewer and answers out loud, with follow-up questions on what you say. You choose the role you are preparing for.
Its feedback is strongest on delivery — filler words, pacing, clarity — with a transcript of the session. It works in 24 languages, and the same roleplays cover sales calls, pitches and presentations. Most of its business is teams and companies, which shows in its security certification and its Zoom and Microsoft Teams integrations.
Where it falls short: The free plan is five roleplays in total, not per day or month, and Pro allows up to ten a week (unlimited is the pricier Advanced plan). Ukrainian is not among its languages, and its site doesn’t say whether it reads your CV or the job posting.
Best for: Polishing how you come across — pace, filler words, clarity
Big Interview
- Practice by
- Voice, video (on camera)
- Free
- No free plan; free intro course and a 30-day refund
- Paid
- $39/month · $99/3 months · $299 lifetime access
Big Interview started as an interview-training course built by career coaches and grew into a practice platform. Its PracticeAI is a voice-only AI interviewer — like a phone screen — that builds questions from your resume or a job description and, by its own description, asks probing follow-ups.
Separately, you can record video answers and get feedback on body language, eye contact, pace and filler words. Around that sits a library of over 10,000 interview questions and lessons, including salary negotiation, and a lifetime-access option.
Where it falls short: There is no free plan to try the practice itself before paying, though there is a 30-day refund, and its site doesn’t say which languages it supports. Before paying, check whether your university or career centre already gives you access.
Best for: Following a structured course with a large bank of questions
Final Round AI
- Practice by
- Voice
- Free
- Free plan, but practice interviews need a paid plan
- Paid
- $150/month · $25/month (billed yearly)
Final Round AI is best known for Interview CoPilot, an app that listens to your real interview and suggests answers on screen. Its mock interviews now live inside that app as Practice Interview: you answer a spoken AI interviewer out loud, with follow-up questions, in scenarios from behavioural and recruiter screens to coding, system design, product cases and salary negotiation.
Practice is tailored to your target role, company, job description and resume, and each session ends with a debrief on what worked, what to fix and what to drill again.
Where it falls short: It is the most expensive tool here month to month, practice rounds are not in the free plan, and it runs as a desktop app for macOS and Windows. Its main product is live help during real interviews — see the section on copilots below.
Best for: Coding, system-design and product rounds, if the price fits
Huru
- Practice by
- Video (on camera)
- Free
- Everything, unlimited — no paid plan for job seekers
- Paid
- No paid plan for individuals
Huru is free for job seekers: unlimited mock interviews from a bank of over 50,000 questions for more than 240 roles. Paste a job title and description and the questions follow that job.
You answer one question at a time on camera, on a computer or phone, and each answer gets a score out of 100 with notes on relevance, structure and confidence, plus a stronger version of what you said. There is an iOS app and a Chrome extension that turns a job post into a practice interview.
Where it falls short: It is question by question rather than a conversation — its site doesn’t say the next question reacts to your answer. Practice is in five languages: English, Spanish, Portuguese, German and French.
Best for: Lots of free practice, one question at a time, with a score for every answer
Interviews by AI
- Practice by
- Voice, text
- Free
- 3 questions a month, no card
- Paid
- $9/month
Paste a job description and Interviews by AI turns it into the questions that job is likely to ask. You answer each one by voice or text within a two- to three-minute limit and get STAR-based feedback with a stronger sample answer.
It is the simplest tool on this page and has the cheapest paid plan, and it deletes your audio after transcribing it.
Where it falls short: The free plan is three questions a month. It works question by question — its site doesn’t describe follow-ups — and uploading your resume is a Pro feature.
Best for: Quick practice on the questions one specific job description implies
Tools with real people on the other side
For specialised technical loops, a human who has run the real thing is still the closest rehearsal. Both tools here also have an AI option.
Aced (ex-Exponent)
- Practice by
- Video (on camera)
- Free
- 5 peer mock interviews a month; account needed, no card
- Paid
- Pro $12/month (billed yearly) · AI $20/month (billed yearly)
Aced is the new name of Exponent, the interview-prep membership for tech roles — product management, software engineering, system design, data science — and Pramp is now part of it. Its core is live peer mock interviews over video: you and another candidate take turns interviewing each other.
On top of that come courses, a database of questions reported from real companies, AI mock interviews with instant feedback on its AI plan, and paid one-to-one coaching.
Where it falls short: It is built for tech roles, so outside them there is less to use. The prices in the table are with yearly billing, and its site doesn’t say whether the AI interviewer follows up on your answers.
Best for: Product, engineering and data interviews at tech companies, practised with real people
interviewing.io
- Practice by
- Voice, shared code editor
- Free
- AI Interviewer for coding and system design
- Paid
- from $179/session
interviewing.io sells anonymous mock interviews with engineers from companies such as Google, Meta and Amazon, over audio and a shared code editor, without video. You get a real interviewer’s judgement — the closest thing to the actual loop.
It also has a free AI Interviewer that simulates FAANG-style coding and system-design rounds.
Where it falls short: Human sessions are priced per interview and are the most expensive way to practise on this page, and its focus is software engineering.
Best for: High-stakes engineering interviews, with an engineer from a big tech company
Tools we left out, and why
A few names you may have expected in the table:
- Google Interview Warmup — For years the default free answer. Its page now shows a general article on preparing for interviews that points to Gemini Live instead, and we could no longer find the tool itself.
- Oliver — AI role-play for sales and customer-service calls, where the AI plays the customer rather than the interviewer — useful if your hiring process includes a mock call. Their own comparison covers those tools (and mentions Colloqa).
- Verve AI — Sold mainly as a live interview copilot, like Final Round AI’s main product; mock interviews are a side feature, with five in its free plan.
- Pramp — Now part of Aced — new Pramp sessions have been hosted there since July 2024.
Which one should you use?
- You want it to feel like a real conversation, out loud. Pick a tool whose AI follows up on your answers: Colloqa · Yoodli · Big Interview
- You want to pay nothing. Huru is free and unlimited, one question at a time; Colloqa gives you a full interview every day; Aced includes peer mock interviews on its free plan: Huru · Colloqa · Aced (ex-Exponent)
- The interview is not in English. Check the tool speaks your language before anything else: Colloqa · Yoodli · Huru
- It is a coding or system-design loop. Practise with engineers, or with an AI built for technical rounds: interviewing.io · Aced (ex-Exponent) · Final Round AI
- You would rather follow a course than improvise. A structured curriculum with thousands of questions: Big Interview
- You mostly want to fix how you come across on camera. Tools that analyse delivery — pace, filler words, eye contact: Yoodli · Big Interview · Huru
- The interview comes first and the salary conversation right after. Rehearse both: Colloqa · Final Round AI
Practice tools vs live interview copilots
Search for "AI interview" and you will also find copilots — apps that listen to your real interview and put suggested answers on your screen while you talk. That is a different category, and this page compares practice tools only.
A copilot works during the interview; a practice tool works before it. Reading an answer off a screen while someone watches you is hard to do naturally, and many employers treat it as cheating if they find out. Rehearsing until the words are your own has neither problem — and it still works when the interview is in person.
If the conversation is not an interview
Most mock interview tools stop at the interview itself. If what is coming up is the offer call after it, or a hard conversation at work, Colloqa covers that too:
The fastest way to compare is to try one. A Colloqa interview takes about a minute to set up, and there is a free one every day.
Start a free mock interviewQuestions people ask
It depends on what you need from free. Huru has no paid plan for job seekers, but you answer one question at a time on camera rather than holding a conversation. Colloqa gives you 1 full interview a day for free — an AI interviewer that follows up on your answers — with up to 45 minutes of voice and no card. Yoodli’s free plan is a handful of roleplays in total, and Aced’s includes mock interviews with other candidates. Google’s Interview Warmup, long the usual free answer, is no longer available.
Some do. Colloqa, Yoodli, Big Interview’s PracticeAI and Final Round AI’s practice interviews say their AI follows up on your answers. Huru and Interviews by AI work question by question: you get feedback on each answer, but their sites don’t say the next question depends on it. Follow-ups matter because that is where interviews are usually decided — the second question about the project you just mentioned.
Yes, with some tools. Colloqa runs interviews in 12 languages — English, Ukrainian, Polish, Spanish, Portuguese, German, French, Italian, Dutch, Korean, Japanese and Czech — and you can switch mid-conversation. Yoodli lists 24 languages (Ukrainian is not among them), Huru five, and Final Round AI advertises many more. Big Interview, Interviews by AI and Aced don’t say which languages they support.
No. A mock interview tool is for rehearsing before the interview. A copilot listens to the real interview and suggests answers on screen while you talk — many employers treat that as cheating. This page compares practice tools only.
From nothing to a few hundred dollars. Huru is free; Colloqa is free for 1 interview a day and $8.99/week or $19.99/month for unlimited practice; human mock interviews with engineers cost the most. The table above lists every tool’s prices as shown on its own site on the date it was checked.
They do different jobs. A person who runs real interviews gives you a judgement no AI can — worth paying for before a high-stakes technical loop. AI lets you practise tonight, at 2 a.m., as many times as you need, until the answers come out the way you mean them. Many people do the reps with AI and book one human session at the end.
