“AI mock interview” has become one label stuck on four different products. Some tools play the interviewer and talk with you. Some record your video answers and score them. Some connect you with a human engineer. And a growing number do not do practice at all: they listen to your real interview and put suggested answers on your screen while it happens.
Before going further, a disclosure. I build Tough Tongue AI, one of the tools on this list. I have tried to be straight about where each tool fits and where ours falls short. I also checked every price in this post on the vendor’s own pricing page on September 28, 2026, because the lists that rank these tools today are full of stale numbers. One of them still ranks a tool that no longer exists.
Here is how the seven platforms compare for practice, and what to look for in the round you are actually facing.
How I evaluated these tools
I looked at five things, in the order they matter for most candidates:
- Does the round feel like the real one? A real interviewer asks a follow-up based on what you just said, interrupts when you ramble, and pushes back on a weak answer. A list of preset questions read aloud is not the same practice.
- Does it cover your round, with its tools? A PM interview happens in a shared doc, a coding round in an editor, a system design round on a board, and a consulting case with exhibits handed over one at a time. Practice without those tools skips the hard part.
- Is the feedback specific? Scored against a rubric, backed by what you actually said, and covering delivery as well as content.
- Where does practice happen? A browser tab, a desktop app, a phone, or the same Google Meet or Zoom window your real interview will use.
- What does it cost to practice enough? One mock does not change much. Ten or twenty do. I compared the price of the cheapest plan that includes AI or human mocks, billed monthly and annually.
1. Tough Tongue AI
Tough Tongue AI is built around one idea: the practice round should look like the real round. The interviewer is a voice AI that runs the conversation, asks follow-ups from what you said, and changes its tools depending on the interview type.
The interviewer opens the tools the real round uses
In a PM interview, the AI opens a notepad so you write your structure live, the way you would in a shared doc during a Google or Meta PM round. In a coding or SQL interview it opens an editor and asks you to talk through your approach while you type. In a system design interview it opens an architecture board, scribes your requirements into a shared notepad, watches the design as you build it, and probes every box you place. In a consulting case it drives a slide deck and hands you exhibits one at a time, the way a McKinsey interviewer does.
That last part matters more than it sounds. Most AI case practice is a voice or text chat with no exhibits, and it runs for ten to fifteen minutes. The MBB case collection has 35 full-length, interviewer-led cases built from real casebooks, where the interviewer says “let me pull up Exhibit A” and the slide flips to the chart. It does not correct your math for you. It asks you to walk through the calculation until you find the error, and the report notes that it had to.
The library, and custom interviews
There are more than 500 pre-built mock interviews, organized into collections for product management, coding, system design, TPM, data science, tech business strategy, and MBA admissions, plus the MBB case collection. If your role is not covered, you can describe it or paste the job description and build a custom interview in a few minutes.
Feedback on what you said and how you said it
Because the interview is voice, the report covers delivery as well as content: confidence, clarity, pacing, and structure. With the camera on, it also reads expression and body language. System design rounds are graded against a reference design, and case interviews against the case’s answer key, weighted the way firms weight it. Case reports back each score with a quote of what you said, then add a hire band (strong hire, hire, borderline, no hire) and a percentile against everyone else who has run the same case.
It can join your Google Meet or Zoom call
This is the part no ranking I read covers. The same AI interviewer can join a Google Meet or Zoom call as a participant and run the interview there. A lot of first rounds now happen on a video call, and rehearsing in that exact window, with your own camera and the meeting clock running, takes one more new thing off the table on the day. The meeting agent is included from the Starter plan. Microsoft Teams is not supported yet.
Start an interview from ChatGPT or Claude
A lot of prep now happens inside ChatGPT or Claude: you read about a system, ask questions, and sketch an answer. Tough Tongue AI’s MCP server lets you turn that into practice without leaving the chat. Ask for an interview on the topic you just studied, and a practice link comes back in the same conversation. It is included on every plan, and the build your own interviewer section below shows the open-source skills behind it.
Truely, for the live conversation
Practice is the main event, but we also make Truely, a desktop assistant for macOS and Windows that listens to a live conversation, such as an interview or a sales call, and suggests what to say. It is hidden from screen share by default. It comes with the same plans as the mock interviews, and whether you use it in a real interview is between you and the company you are talking to.
Pricing
You get 25 free minutes to try it, with no card. Starter is $20 per month for 150 minutes, and Pro is $99 per month for 900 minutes that roll over. Career centers, bootcamps, and clubs can put a cohort on a team plan, invite students in bulk by CSV, and see progress by student and by interview in one dashboard. Kellogg used the same platform to design an AI oral exam.
Where it falls short
An AI interviewer cannot judge presence the way a partner or hiring manager does, so practice the “would I put this person in front of a client” part with people too. There are no human interviewers on the platform. The library leans toward tech, product, consulting, and MBA interviews, so for other fields you will be building a custom interview rather than picking one off the shelf. And every case in the MBB collection is interviewer-led, so Bain and BCG candidates should also practice driving a case themselves.
Best for: PM, system design, coding, and consulting candidates who want the round to look like the real one, including on Meet or Zoom.
2. Interviewing.io
Interviewing.io runs anonymous mock interviews with engineers from companies like Meta, Google, OpenAI, and Amazon. You join your interviewer in a shared code editor with audio and chat, and by design there is no video. Its FAQ says interviewers need FAANG or similar experience, four or more years in the field, and at least 20 interviews conducted. It covers algorithms and data structures, system design, machine learning, front-end, engineering management, and behavioral rounds, and you can ask for an interviewer from a specific company.
Each session ends with a detailed rundown of what went well and what to fix. It also offers a free AI Interviewer that simulates a FAANG-style interview for coding and system design, and 200 free problems from Beyond Cracking the Coding Interview.
Pricing is per session. The FAQ says interviews start at $179, and the price varies with the subject and whether you want an interviewer from a particular company. Exact per-type prices appear only in the booking flow after you sign up. It offers a full refund if you are unhappy with an interview.
Best for: software engineers who want a human interviewer from a top tech company and will pay per session for it.
3. Yoodli
Yoodli started as a speech coach and is now sold mostly to companies, as a roleplay platform for teams practicing high-stakes conversations. Interview practice is one use case among several. In interview mode, the AI asks preset questions and mixes in follow-ups based on your answers. The microphone is required and the camera is optional, and with the camera on you get feedback on body language and framing.
The feedback is its strength: pacing, filler words, clarity, confidence, structure, and talk time. It can also sit inside a real Zoom, Google Meet, or Teams call and nudge you to slow down or hit your talking points, which is delivery coaching rather than suggested answers. Coding, system design, PM, and case interviews are not among the interview types it describes. It shipped an MCP connection for Claude and Copilot in April 2026, set up by a Yoodli org admin.
Pricing is published. The free Starter plan includes 5 roleplays in total. Pro is $11 per month billed monthly or $8 per month billed annually, for up to 10 roleplays a week. Advanced is $28 per month billed monthly or $20 billed annually, with unlimited roleplays. Team and Enterprise plans are custom.
Best for: behavioral and general interviews where delivery is the main thing to fix. We have a full Tough Tongue AI vs Yoodli comparison if you are weighing the two.
4. Aced (formerly Exponent)
Exponent is in the middle of renaming itself Aced, and Pramp, the free peer mock site, is now part of it. It is a full interview prep platform: courses across a dozen tech roles with a strong PM focus, a large question bank, peer mocks, AI mocks, and paid coaching.
The AI mock interview connects you by audio to an AI interviewer for 10 to 20 minutes, and it is scored on rubrics modeled on real tech company interviews. Its own page says the AI mock does not support technical interviews or live coding yet, so it covers behavioral and PM questions. The peer mocks cover much more: algorithms, system design, PM, behavioral, data science, SQL, front-end, and finance, with a shared code editor for technical rounds. You and a peer take turns interviewing each other.
The free Basic plan includes 5 peer mocks a month. Pro is $79 per month billed monthly or $12 per month billed annually. AI mock interviews come with Expert, which is $99 per month billed monthly or $20 per month billed annually. Coaching is priced separately. It also sells a university plan with a dashboard for career centers.
Best for: PM candidates who want courses, a question bank, and peer mocks in one subscription.
5. Big Interview
Big Interview is a job interview training platform sold heavily through universities and workforce programs. It has two practice modes. VideoAI scores recorded video answers on body language, eye contact, pace, filler words, and vocabulary. PracticeAI, launched in September 2025, is an audio-only, voice-to-voice interview that builds questions from a job description and your resume and asks follow-ups. PracticeAI scores role alignment, clarity, and confidence, awards a bronze, silver, or gold medal, and shows sample answers.
It covers behavioral, technical, and situational questions across industries and seniority levels, with a large question library. Coding, system design, and case interviews are not among its stated formats.
For individuals, Interview BootCamp is $39 for 30 days, Interview Accelerator is $99 for three months, and Interview Pro is $299 for lifetime access, with a 30-day refund guarantee. How many PracticeAI interviews a personal plan includes is not stated. Organizations get custom pricing, and students at many schools get access through their career center.
Best for: students and job seekers doing behavioral and situational interviews, especially if their school already provides it.
6. Huru
Huru is a video interview prep app on the web, iOS, and as a Chrome extension. You build an interview from its library, from a job post through the extension, or by pasting a job description, then record your answers on video. It gives real-time nudges on pacing and keywords during practice, and afterwards it scores relevance, missed points, filler words, grammar, and confidence from your tone and energy, with an example answer for each question.
It focuses on behavioral interviews and the STAR method, with tracks for software engineering, data science, product management, and marketing. Coding editors, system design, and case interviews are not among its stated features.
Starter is $24.99 per month, and Growth is $99 per year, which Huru describes as $8.25 a month. Both include unlimited mock interviews, and there is a free trial. It also sells to universities and workforce organizations.
Best for: behavioral interview practice on video, on your phone or laptop.
7. Final Round AI
Final Round AI is best known for Interview CoPilot, a desktop app for macOS and Windows that listens to a live interview and shows suggested answers in a private window. Its mock product is now called Practice Interview and lives inside the same app. You pick one of eight types (general, coding, system design, behavioral, product case, data and ML, salary negotiation, or recruiter screen), answer out loud to an AI interviewer, and get an automatic debrief that flags your weakest moments to drill again. Practice is tailored to a saved goal with your role, company, job description, and resume.
No code editor or whiteboard is stated for practice rounds. Screen Help, a copilot feature, reads coding and system design prompts off your screen during real interviews.
Pricing is published but inconsistent across its own pages. On September 28 the subscription page listed a Free plan with “unlimited mock interviews”, while the Practice Interview page says a practice session requires an active paid plan. Paid plans were $150 per month billed monthly, $83.33 per month billed quarterly, $25 per month billed annually, and Premium MAX at $41.67 per month billed annually. Monthly plans are non-refundable.
Best for: candidates who want practice rounds and a live copilot in one desktop app. See the Tough Tongue AI vs Final Round AI comparison for a side-by-side.

Prices were checked on each vendor’s pricing page on September 28, 2026. “Not stated” means none of the official pages I read says it. Some vendors show different prices by region: LockedIn AI and Verve AI showed only Indian rupee prices from an Indian connection, and LockedIn says its mobile app costs more than its website.
What happened to Google Interview Warmup
Four of the eight lists that AI assistants cite most for this question still rank Google Interview Warmup, and one ranks it first. It is gone. On September 28, 2026 its Grow with Google page redirected to an interview tips article, and that article suggests practicing with Gemini Live instead. Third-party sites date the retirement to around April 2026.
If you liked it because it was free and needed no account, a general voice assistant like Gemini Live or ChatGPT’s voice mode is the closest replacement. It works for a quick behavioral warmup. It will not keep a rubric, open a notepad or a board, show you an exhibit, or give you a report to compare across attempts. The guide to practicing case interviews by yourself has a prompt we tested for ChatGPT and the three places it breaks, and most of those lessons apply to any interview type.
Mock interviews and live copilots are different products
Three of the tools that show up on these lists, Final Round AI, LockedIn AI, and Verve AI, lead with a live copilot. It listens to your real interview, reads the question, and shows you a suggested answer while you speak, usually with a stealth mode that hides it from screen sharing. Some of them also include practice rounds. We make one too: Truely, a desktop assistant for interviews, sales calls, and other live conversations, separate from our mock interview platform.
That is a different product from a mock interview, and it raises a different question: whether the company interviewing you allows outside help during the round. Many say no in their interview instructions. Check before you rely on one. The rest of this post is about practice, where the goal is that you need no help on the day.
Which one should you choose
Start from the round you are facing, not from the feature list.
Choose Tough Tongue AI if your round has an artifact in it: a PM structure, code, a system diagram, or a case exhibit, or if you want to rehearse inside the Google Meet or Zoom window the real interview will use.
Choose Interviewing.io if you are a software engineer and want a human interviewer from a specific top company, and paying per session fits your budget.
Choose Yoodli if the content of your answers is solid and the delivery is what needs work.
Choose Aced if you are a PM candidate who wants courses, a question bank, and peer mocks in one place.
Choose Big Interview or Huru if you are preparing for behavioral and situational interviews and want to see yourself on video.
A practice loop that works
Whatever tool you pick, the loop matters more than the tool. One mock gives you a report. A loop changes how you interview.
- 1Run it coldPick a medium interview and treat it like the real one. No notes, no pausing.
- 2Read the report against the transcriptFind the one or two moments that cost the most, in your own words.
- 3Redo only the weak partRerun the same interview and fix those moments before trying a new one.
- 4Dress rehearsal where the real round happensRun the last mock on Google Meet or Zoom with your camera on.
Spread the loops across the weeks before your interviews rather than cramming them into the last two days. Two or three loops a week on your weakest round type beats ten mocks the night before.
Build your own interviewer
If your round is not in any library, you can build the interviewer yourself from the AI assistant you already use. Tough Tongue AI has an MCP server, so Claude, ChatGPT, Codex, and Cursor can create an interview scenario for you in plain English. There is also an official ToughTongue AI app in ChatGPT.
Our community skills repo has open-source skills for the interview types that need the most setup. system-design-interview-builder turns system design material, such as a video transcript, an article, or your notes, into a mock interview with an interviewer-controlled notepad and an architecture board, case-interview-builder turns a casebook case into an interviewer-led case with an exhibit deck and a hidden answer key, and pm-scenario-builder turns any PM case study into a mock interview. The quickest setup installs the core plugin, which brings the MCP server, and the community skills into every coding agent on your machine:
npx plugins add tough-tongue/toughtongue-skillsnpx plugins add tough-tongue/ttai-community-skillsThen ask, for example: “Build a system design interview for a URL shortener, graded against this reference design.” Career center staff and bootcamp instructors can use the same route to build one interview for their program and share it with a whole cohort. The setup for every client is on the agents page.
Start here
Pick the round type you are least ready for, block forty minutes, and run one mock like it counts. Then read the report and run the same interview again. It will feel messier than reading answers did. That is the point.
If you want to try the tools-in-the-round approach, the AI interview practice page lists every collection, and the first 25 minutes on Tough Tongue AI are free.
“Walk me through how you would structure this. Use the notepad.”
