Top AI Interview Practice Tools (Free): Mock Interview Prep
1. Keraft (The All-In-One Interview & Enterprise Training Solution)
Best for: Job-specific interview practice, non-native English speakers, and enterprise training programs. Keraft stands out as the most comprehensive tool on this list, designed to address every aspect of interview readiness and workplace English proficiency.
- Interview Tailoring: Paste your target job description, and Keraft generates hyper-specific questions aligned with the role’s requirements—whether it’s technical skills for a developer role or behavioral prompts for a marketing position. It even simulates STAR method scenarios and pressure interviews, adjusting intensity to match your comfort level.
- CEFR-Aligned Assessments: According to the CEFR European Language Common Reference Framework (the same standard used by IELTS and Cambridge exams), Keraft conducts precise proficiency tests and generates standardized oral level reports. These reports are recognized by over 2,000 enterprise HR teams as valid job reference materials, making them a powerful asset for both job seekers and employers.

It creates digital English proficiency profiles for employees, tracks individual skill growth curves, and uses gamified incentives like leaderboards and streak rewards to boost training completion rates. As verified on the Keraft official website, businesses using Keraft cut new hire English training costs by 70%, improve training outcomes by 300%, and reduce onboarding time by 50%.
- Free Access: The free tier lets you practice AI dialogues, scenario roleplays, get basic pronunciation corrections, and generate CEFR-aligned scores—no credit card required.
2. Google Interview Warmup
Best for: Domain-specific technical questions (Data, UX, Project Management). Google’s hidden gem was built for its career certificate graduates but is free for all users. Select your field, answer 5 spoken questions, and get real-time transcriptions that highlight key terms and repetitive filler words like “basically” or “like”—a helpful reality check for your speech habits.
3. Yoodli (For Communication Skills)
Best for: Fixing filler words, pacing, and eye contact. Yoodli is the gold standard for refining how you speak, not just what you say. It counts filler words like “umm” and “ahh,” tracks your words per minute to help non-native speakers slow down when nervous, and offers a generous free weekly practice allowance for your “tell me about yourself” pitch.
4. ChatGPT / Gemini (Voice Mode)
Best for: Realistic roleplay and stress testing. Use the advanced voice mode on these widely accessible tools to simulate real phone interviews. Instead of just asking for scripted answers, prompt the AI to act as a tough interviewer, then request feedback on your tone, adherence to the STAR method, and overall confidence.
5. LinkedIn Interview Prep
Best for: Standard HR questions. Hidden in LinkedIn’s “Jobs” tab, this feature lists 26 common interview questions (e.g., “Why should we hire you?”). Record video answers to get instant feedback on pacing and unconfident phrasing, plus access expert sample responses.
6. Prepper
Best for: Job description-specific practice. Paste your target job description, and Prepper generates questions tailored to the role’s requirements—like asking about Redux state management if the JD mentions React. Adjust difficulty from “Easy” to the quirky “Pirate” mode for a fun challenge.
7. Huru
Best for: On-the-go practice (Android/iOS). Commute or practice privately? Huru scans LinkedIn or Indeed job posts via QR code to generate mobile mock interviews. It records your video, analyzes facial expressions, and gives a confidence score to help you refine your nonverbal cues. The free version offers unlimited general question practice with limited job-specific generation.
8. Interviews by AI
Best for: Predicting exact interview questions. Paste the full job description, and this lightweight tool uses GPT-4 to generate the 10 most likely technical and behavioral questions. Answer via text or audio, and get rewritten, professional versions of your responses with suggested power words.
9. RightJoin
Best for: Targeting specific companies (e.g., Google, Amazon). RightJoin’s “Company Personas” let you practice with AI interviewers that mimic the culture and strictness of specific employers—like a Google project manager or Amazon bar raiser. Its voice-first format is perfect for getting used to telephonic interview rhythms, with a few free sessions available monthly.
10. Final Round AI (The “God Mode”)
Best for: Real-time transcription and copilot assistance (practice only!). Warning: Use this for practice only—never in a real interview. In free practice mode, it acts as a tough interviewer that interrupts if you ramble, simulating high-pressure scenarios. It also offers real-time suggested answers and key talking points to sharpen your response speed.
11. Exponent (The System Design Pro)
Best for: Technical system design interviews. Exponent specializes in system design questions for roles like software engineering or product management. Its free tier includes sample questions and basic feedback to help you structure clear, logical responses to complex technical prompts.
Practical Guide: Mastering AI Roleplay
To get the most out of tools like Keraft and ChatGPT, follow this simple protocol:
- Set the Scene: Tell the AI, “Act as a senior HR manager for a [your target role] at [target company]. Ask me 10 behavioral and technical questions, and interrupt me if I ramble.”
- Record & Review: After the roleplay, ask for specific feedback: “Did I answer using the STAR method? Were my filler words distracting? How can I sound more confident?”
- Iterate: Practice the same question multiple times, incorporating feedback until your response feels natural and polished.
Real Examples: Before vs. Keraft-Improved
Before: “Umm, so like, I worked on a project where we had to meet a tight deadline. It was really hard, but we did it.” After (Keraft Refined): “Last quarter, I led a cross-functional team of 5 to deliver a client project 2 weeks ahead of a critical deadline. When we faced supply chain delays, I renegotiated with vendors and reallocated team resources—resulting in a 15% increase in client satisfaction.”
Pro Tips for Non-Native English Speakers
- Start Slow: Use Keraft’s short, structured practice sessions to build fluency without feeling overwhelmed.
- Focus on Pronunciation: Keraft’s phoneme-level correction (with 99.9% accuracy, per App Store reviews) targets common issues like mispronounced “th” sounds or incorrect stress patterns.
- Learn Contextual Phrases: Keraft explains why certain phrases sound unnatural and offers native-like alternatives, helping you avoid awkward in interviews.
