Solve interview-style problems in a distraction-free editor, then get an AI review of your correctness, approach and complexity — plus a clean reference solution. Pick your language.
01Check in
Pick the role — or paste a real job posting.
02The interview
An AI interviewer asks; you answer by voice, video or text.
03Readiness score
Scored with tips, a model answer and a study plan.
Who it's for
Software engineers preparing for technical / live-coding rounds.
What you'll practise
Built-in code editor with syntax highlighting (no setup)
Problems in Python, JavaScript, TypeScript, Java, C++, Go and more
AI review of correctness, approach and time/space complexity
A clean reference solution to compare against
Sample questions
A taste of what you'll be asked.
- 01Given an array of integers, return indices of the two numbers that add up to a target.
- 02Determine whether a string of brackets is validly balanced.
- 03Merge a set of overlapping intervals.
- 04Explain the time and space complexity of your approach.
Your live mock generates fresh, tailored questions each time — these are just a taste.
Questions & answers
Does it run my code?
Submissions are AI-reviewed rather than executed — you get feedback on correctness, approach and complexity, plus a reference solution. It's about reasoning and communication, not a judge.
Which languages are supported?
Python (default), JavaScript, TypeScript, Java, C++, Go, C# and Ruby, with syntax highlighting in the editor.
Is coding practice free?
Coding mode is part of the premium deck. You can explore the flow, and a one-time pass unlocks unlimited practice.
