Recommended Free Tools
No single AI tool is the best choice for every candidate. The right one depends on the interview you are actually facing: behavioral or first-round screening, coding or system design, product interviews, spoken delivery, or a quick drill built from a specific job description. The eight tools below are grouped by that fit. Prices and free limits come from Huru’s comparison page, which states that it checked vendor pages on September 30, 2026. Huru also sells one of the tools listed, so its rankings and feature descriptions are the publisher’s own claims, not independent tests. This article does not report hands-on testing of any product.
Start with the interview you have, not the most popular tool
Before comparing products, decide which format your interview will use. A behavioral screen rewards structured stories about past work. A coding round rewards problem solving under time pressure. A product interview rewards clear reasoning about users and tradeoffs. Choosing a tool built for a different format wastes practice time, even when the product itself is good.

Once you know the format, compare each candidate tool on five points:
Free tools Windows power users keep installed
One-click scans. No signup required.
- Role and format fit: behavioral, coding or system design, product, or general interviews.
- Practice mode: video, voice, text, peer practice, or a human expert.
- Feedback type: answer structure, delivery, technical problem solving, or a fixed curriculum.
- Input: whether questions can be built from the target job description and your resume.
- Free limits and total cost: what you can do without paying, and what a realistic plan costs.
The eight tools at a glance
The table reflects Huru’s comparison page as checked on September 30, 2026. Plans and free allowances change often, so confirm each one on the vendor’s own pricing page before you pay. “Not stated” means the comparison did not give that value; it does not mean the tool has no paid plan.

Tool-by-tool fit
Huru: spoken, camera-based practice for behavioral questions
Huru is the closest match if you want to answer out loud on camera and get a scored review. Its product page says the tool rates answers on relevance, structure, specificity, impact, and articulation, and lets you review your recordings. Huru describes the score as coaching feedback, not a hiring decision or an offer guarantee. Those are vendor statements about its own product, so treat the scoring dimensions as a description of what the tool says it measures.
interviewing.io: coding and system design
This is the option for engineers preparing for technical rounds. Its human sessions are with engineers, and its free AI interviewer covers coding and system design practice. Use the AI interviewer for repetition and book a human session when you need a realistic technical interviewer.
Aced (formerly Exponent): peer and AI practice for tech and product roles
Aced suits tech and product candidates who want to practice with peers, not just a bot. Huru’s comparison reports that Pramp moved into Exponent and that Exponent is now Aced. Peer practice depends on other users being available, so plan around the free monthly allowance rather than assuming unlimited sessions.
Yoodli: delivery through roleplay
Yoodli is built around spoken delivery. Its roleplays are useful if you already know your answers but want to rehearse saying them aloud under a conversational setup. Its free allowance is limited to five lifetime Starter sessions, so it works best as a short, targeted tool rather than a daily one.
Rank #2
Big Interview: lessons before practice
Big Interview suits candidates who want instruction first. Its structured lessons come before video practice, so it works best if you need to learn a method, such as organizing stories, before you practice them. It has no free plan, so compare its one-month price against how many sessions you expect to run.
Interviews by AI: quick drills from a job description
This tool is for short sessions when time is tight. It offers quick spoken or written checks based on a job description, which makes it useful the night before an interview. Because the free allowance is three questions per month, it is a spot-check tool rather than a full practice program.
ChatGPT: flexible practice that depends on your prompt
ChatGPT is a general-purpose option, and its quality depends on how you set up the session. Specify the role, the company type, the interview style, and whether you want follow-up questions. Its free plan includes limited voice chats, and paid plan availability and pricing vary by country, so check what applies where you live.

Huru’s comparison characterizes Final Round AI mainly as a live-interview assistant, with practice interviews available in its Pro plan. That is a different use from rehearsal. Keep preparation practice separate from anything you would use during a real hiring interview, and confirm that the employer allows the tool before you consider using it in that setting.
Discontinued and renamed services: what is still unclear
Google Interview Warmup
Huru’s comparison reports that Google Interview Warmup was retired in March 2026. A separate comparison dated August 2026 could not find a Google-published retirement notice or confirm the live product page, so it did not verify the retirement. Until you can confirm the status on a Google page yourself, do not plan your preparation around this service.
Pramp
Pramp is now part of the Aced lineage, according to Huru’s comparison. The sources here do not establish whether Pramp still operates as a separate free service. If you want free peer practice, check Aced’s current terms and its free monthly allowance rather than assuming Pramp’s older free offer still applies.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can an AI mock interview replace practice with a person?
It should not. Huru’s comparison notes that an AI may mishear words and does not know your employer or the team you are interviewing for. Its recommendation is to finish with at least one practice session with a person, ideally someone who knows the role or the hiring process. Use the AI tools for repetition and feedback on structure and clarity, and use a person to test how you handle an unfamiliar interviewer and follow-up questions.

Neither Huru’s materials nor the academic work discussed below show that practicing with these tools improves job offers.
What the academic work shows about AI-generated questions
A 2026 paper by Wen et al., titled “PolyInterview: An LLM-based Platform for Immersive Mock Interview Practice with Comprehensive Multimodal Assessment,” was posted on arXiv on July 11, 2026. The platform described there is an academic system, not one of the eight commercial tools above, and it is publicly accessible. It generates questions from a target job description and CV, conducts multi-turn spoken interviews with follow-ups that respond to the candidate’s answers, and evaluates textual, vocal, and non-verbal behavior.
The result most often cited from the paper is that, in the authors’ analysis, the questions generated for a session matched that session’s job description more closely than job descriptions from other roles in 93.7% of sessions. This measures how well questions fit the role. It does not measure interview success, hiring outcomes, or how the commercial tools perform.
Do you need a webcam?
Camera-based practice, such as Huru’s, is only as useful as your ability to review yourself. A built-in laptop camera is often enough to check eye contact, posture, and pacing. A separate USB webcam is worth considering only if the built-in camera makes the recording hard to watch. This article does not test or recommend a specific webcam.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteA practical sequence for using these tools
- Match the tool to your interview format using the table, and confirm the current price and free limit on the vendor’s site.
- Load the target job description and your resume where the tool accepts them, so the questions reflect the actual role.
- Record or review each answer, then compare the feedback with your own judgment. Revise the answer, then practice it again.
Once you can answer your core questions cleanly, book a session with a person before the real interview.
The Bottom Line
For most candidates, the right starting point is the tool whose format matches your next interview, not the one with the longest feature list. Pick a free option first where one exists, verify current pricing before paying, and be cautious about any service whose status these sources do not confirm.
