Practice with an AI Mock InterviewerBehavioral · Technical · System Design · Case · Free credits, no card

An AI mock interview is a practice job interview run by an AI interviewer instead of a human. The AI asks role-specific questions (behavioral, technical, system design, case), listens to your spoken answer, and gives structured feedback on what to improve. Modern AI mock interview platforms like OphyAI ground questions in your actual resume, score you across multiple dimensions (Communication, Technical, Problem Solving, Confidence), and let you replay the session with the full transcript afterward.

Yes. OphyAI's Free plan includes a one-time 5-credit grant, which covers one Interview Practice session capped at 15 minutes with no credit card required. On a paid plan, the first Practice session is credit-free; later sessions use 10 credits for text or 15 for voice.

There is no universal winner. OphyAI supports behavioral, technical, system design, and case practice with resume and job-description context. The one-time 5-credit signup grant covers one session capped at 15 minutes, and Pro is $29 per month. Compare other platforms by practice format, feedback depth, role coverage, and current plan access.

Three differences. First, voice — a real AI mock interviewer listens to you speak (not type), which is closer to the actual interview. Second, scoring — purpose-built tools rate you on rubric dimensions (Communication, Technical, Problem Solving, Confidence) where ChatGPT just chats. Third, role context — OphyAI loads your actual resume and the target company/role, so the questions and follow-ups match your background instead of generic prompts. ChatGPT is a fine first step; a dedicated AI mock interview tool is what you graduate to when the stakes are real.

Yes. OphyAI's mock interview includes dedicated tracks for system design (drop in a whiteboard photo or diagram and get a component-level review) and live coding (screenshot LeetCode/CoderPad/HackerRank problems and get streamed approach + working code). The AI mock interviewer asks design or coding questions, listens to your reasoning out loud, and follows up like a real interviewer would. See /coding-interview for the technical-round details.

After each session, OphyAI generates a scored report across four dimensions: Communication (clarity, structure, pacing), Technical (accuracy, depth, framework use), Problem Solving (approach, edge cases, trade-offs), and Confidence (filler words, hedging, decisiveness). You also get a full transcript with timestamped highlights and a PDF export to share with a coach or compare across sessions. Scores are calibrated against thousands of real interview transcripts, not just LLM intuition.

Yes — particularly for the behavioral and system design portions. For pure DSA practice, sites like LeetCode and NeetCode still win on problem volume, but they don't simulate the spoken interaction with an interviewer. OphyAI's AI mock interview for software engineers covers behavioral STAR storytelling, technical phone screens, system design with diagram review, and live coding with screenshot capture. Pair it with LeetCode for the algorithm muscle memory.

OphyAI is candidate-facing — it's the interview practice tool you use to prepare. For recruiter-side AI that integrates with an ATS (Greenhouse, Lever, Workday) and conducts AI-led screening interviews against a rubric, look at HireVue, Sapia, Modern Hire, or BrightHire. Those platforms offer ATS integrations, structured scorecards, and bias auditing. They're a different product from candidate-prep tools.

Yes. OphyAI supports mock interviews in 35 languages including Hindi, Spanish, Portuguese, French, German, Arabic and Mandarin — both for the AI interviewer's voice and for your spoken answers. This is useful if you're interviewing for a role in a non-English-speaking country or want to practice answering in your native language before switching to English on the live call.

Default sessions run 30 minutes (5 questions, behavioral) or 60 minutes (longer technical/case format). You can stop early — credits prorate for the time used. After the session you get the scored report and full transcript. Most users run 3–5 mock interviews leading up to a real onsite, increasing in complexity and pressure each time.

Five rules: (1) upload your real resume so the questions match your actual background; (2) speak out loud — typing answers defeats the point because real interviews are spoken; (3) record the session and listen back to the transcript — what you say versus what you think you said is usually different; (4) escalate difficulty session-over-session: behavioral first, then technical, then case/system design; (5) end each session by writing down the two weakest answers and re-running them in the next mock — repetition on weak spots is where mock interviews actually move the needle.
