See it in action

One platform. Every interview.

Real tools, real execution, real feedback — not flashcards. Here's what each mode actually looks like.

Coding Interviews

Code with an AI that thinks like an interviewer.

Talk through your approach. Then prove it. Solve algorithms interview problems in a real editor while the AI probes your reasoning, nudges you when you're stuck, and never just hands over the answer.

  • Python, C++, Java & JavaScript with a built-in test runner
  • Live pass/fail on real test cases as you iterate
  • Hints, follow-ups, and complexity discussion on demand

ML Coding

A real notebook. Real execution.

Implement models from scratch — and actually run them. A Jupyter-style notebook runs Python right in your browser, so you build preprocessing pipelines, models, and algorithms cell by cell.

  • Code & markdown cells with in-browser execution
  • numpy-powered starter notebooks for real ML problems
  • The AI reviews your implementation, not just your output

System Design

Whiteboard architectures on a live canvas.

Diagram it while the AI grills you on the trade-offs. Drag services, databases, clients, queues, and load balancers onto an interactive canvas, then defend your design against real scale requirements.

  • Interactive drag-and-connect architecture canvas
  • Real prompts with functional & non-functional requirements
  • An AI design review on scalability and bottlenecks

ML Design

Design end-to-end ML systems.

From raw data to a deployed model — on one canvas. A purpose-built palette of ML blocks lets you lay out data sources, feature transforms, models, optimizers, and outputs, then talk through the pipeline with your AI interviewer.

  • ML-specific blocks: data, transforms, models, optimizers, loss & outputs
  • Realistic prompts like fraud detection and recommendations
  • An AI review on data flow, modeling choices & trade-offs

Behavioral

Tell your story — and get scored on it.

Turn "tell me about a time…" into muscle memory. Work through STAR-method questions on leadership, conflict, ownership and more, with an AI that reacts to your answers like a real panel.

  • Multi-question sessions with progress tracking
  • Scored across five dimensions after every session
  • Concrete, actionable notes on what to tighten up

Feedback & Scoring

Every session, scored like the real thing.

Know exactly where you stand — and what to fix. End any interview and get a structured report: an overall verdict, a category-by-category breakdown, and specific strengths and areas to improve.

  • Overall verdict with a clear score out of 10
  • Per-dimension breakdown: problem solving, communication & more
  • Downloadable reports so you can track progress over time

Live Feedback

An interviewer that never looks away.

Real-time coaching while you work — no turns, no waiting. Flip on Live Feedback and Mintor watches your code as you type and listens as you think out loud, then chimes in the moment something's worth saying — and can even say it back to you out loud, like a coach sitting beside you.

What's inside

Five ways to get interview-ready.

Pick a mode and start a full mock interview in seconds — each with an AI that thinks, probes, and scores like a real interviewer.

Algorithms

Coding Interviews

Algorithms problems with a built-in editor, live test runner, and an AI interviewer who guides without giving away the answer.

ML Coding

ML Coding Interviews

A Jupyter-style notebook with in-browser execution — implement models, pipelines, and algorithms cell by cell.

System Design

System Design

Draw architecture diagrams on an interactive canvas — services, databases, queues, load balancers — while the AI reviews your design.

ML Design

ML System Design

Design end-to-end ML pipelines on a purpose-built canvas — data inputs, model blocks, transforms, optimizers, and more.

Behavioral

Behavioral Interviews

STAR-method questions on leadership, conflict, and ownership — with detailed scoring across five dimensions.

Feedback

Instant Scoring

Finish any session and get a structured report — an overall verdict, category breakdown, and actionable next steps.

How it works

From cold to confident in four steps.

No setup, no scheduling, no awkward peer swaps. Just open it and go.

1

Pick a mode

Coding, ML coding, system design, ML design, or behavioral — whatever you're prepping for.

2

Interview with AI

The AI asks questions, probes your thinking, and reacts to your answers in real time.

3

Get scored

Receive a structured assessment with scores across multiple dimensions and specific feedback.

4

Track your progress

Every session is saved. Review past transcripts, revisit reports, and watch yourself improve.

Why Mintor

The reps that make the difference.

Interviewing is a skill. Mintor is the gym.

Practice on your schedule

Your AI interviewer is on call 24/7. No booking a peer, no waiting for a mentor — start a mock at 2 a.m. if that's when it clicks.

Feedback in seconds

No more guessing how you did. Get a clear score and specific, actionable notes the moment you finish.

Real tools, not flashcards

A true code editor, an executing notebook, and a diagram canvas — you practice in the environment you'll actually be tested in.

Unlimited reps

Fresh problems every time. Practice the same question type until it's second nature — repetition, without the repeats.

Watch yourself improve

Every transcript and report is saved, so you can look back, compare scores, and see the progress add up.

Practice pressure-free

Fumble, restart, think out loud, take your time. It's the low-stakes room where you make your mistakes — so the real one goes smoothly.

Your next interview starts here.
