Mock interviews with an AI that actually feels like a real interviewer.
Practice unlimited coding, system design, behavioral, and product mock interviews with an AI interviewer that adapts to your resume, your target role, and the company you are interviewing at. Get a transcript, scorecard, and personalized feedback after every session.
Six kinds of mock interviews, one platform
Most mock interview tools only do one thing — coding, or behavioral, or product. Chazle covers every interview format you will face during a real loop, so you can rehearse the entire on-site in one place.
Coding mock interview
An AI interviewer asks LeetCode-style problems, observes your approach in a shared editor, asks clarifying questions, and pushes back on edge cases — exactly like a real Google or Meta engineer would. Supports 50+ languages.
System design mock interview
Practice mid- and senior-level system design rounds: design Twitter, design a URL shortener, design a payment ledger. The AI evaluates your capacity estimates, scaling decisions, and database trade-offs.
Behavioral mock interview
STAR-format questions tailored to your resume and the company's leadership principles. Ideal for Amazon, Apple, and consulting interviews where the bar is on storytelling, not algorithms.
Product / case mock interview
For PMs, business analysts, and consultants — guesstimates, market sizing, RICE prioritization, and product critique cases.
ML / data science mock interview
ML system design, statistics, SQL, and modeling case studies for data and ML engineering roles at top tech companies.
Recruiter screen mock interview
The 30-minute recruiter screen is where most candidates lose offers. Practice it with an AI recruiter who probes salary, motivation, and red flags.
How a Chazle mock interview works
1. Upload your resume and the job description
Chazle's mock interview AI reads both and customizes the questions to your seniority, your tech stack, and the company you are targeting. A senior backend role at Stripe gets very different questions than a new-grad role at Google.
2. Choose interview type and duration
30-minute recruiter screen, 45-minute coding round, 60-minute system design, or a full 4-round on-site simulation.
3. Practice with a realistic AI interviewer
The AI talks to you in voice, listens to your answers, asks follow-ups, and pushes back when your reasoning is weak — just like a human interviewer would.
4. Get a transcript, scorecard, and improvement plan
Every mock interview ends with a detailed transcript, a 7-axis scorecard (clarity, correctness, structure, depth, communication, time management, code quality), and three concrete things to fix before your next session.
Why deliberate mock interview practice changes outcomes
Most candidates over-invest in solving more LeetCode problems and under-invest in actually interviewing. But the only way to get good at interviews is to do interviews — and that is exactly what mock interviews give you, on demand, with no awkward scheduling and no risk to a real offer.
Across 50,000+ Chazle mock interviews, we see a consistent pattern: candidates who complete 5+ mocks before their on-site convert offers at roughly 2.4× the rate of candidates who skip mocks entirely. The biggest gains come from behavioral and system design — the rounds that are hardest to practice alone.
A mock interview also surfaces the "unknown unknowns": the moments where you think your answer is fine but the interviewer is silently scoring you down. Chazle's AI mock interviewer is calibrated against actual FAANG hiring rubrics, so the scorecard reflects how a real interviewer would have rated you.
Mock interview FAQ
What is an AI mock interview?
An AI mock interview is a practice session where an artificial intelligence plays the role of the interviewer. It asks questions out loud, listens to your answers, asks follow-ups, and gives you a written transcript and feedback at the end. Chazle's mock interview AI is trained on real interview transcripts from FAANG and high-growth startups so the experience feels indistinguishable from a real interview.
Is the mock interview really free?
Yes. Your first mock interview on Chazle is completely free, no credit card required. After that, mock interviews are included in every paid plan starting at $8/day or $25/month.
Can the AI mock interviewer evaluate my code?
Yes. The mock interview AI runs your code against hidden test cases, measures runtime complexity, and flags edge cases you missed — just like a hiring manager reviewing your submission.
What companies should I prepare for?
Chazle's mock interview library covers Google, Meta, Amazon, Apple, Microsoft, Netflix, Stripe, Airbnb, Uber, Coinbase, Databricks, OpenAI, Anthropic, and 200+ other tech employers, plus consulting (McKinsey, BCG, Bain) and finance (Jane Street, Citadel, Two Sigma).
Can I do behavioral mock interviews?
Yes. Pick the 'Behavioral' interview type, paste in the company's leadership principles or values, and the AI will ask STAR-format questions calibrated to that company. Amazon's 16 leadership principles are pre-loaded.
How is this different from interviewing.io or Pramp?
Pramp and interviewing.io match you with another candidate or a paid engineer. Chazle's mock interview AI is on-demand (no scheduling), available 24/7, and gives you a structured scorecard instead of free-form notes. It is also far cheaper — peer mock interviews are slow and human-engineer mocks cost $100–$300/session.
