Your guide to the AI-powered code interview. This interview evaluates your ability to write code, solve problems algorithmically, and communicate your approach in real time.

What to Expect

The code interview is a hands-on assessment where you’ll write actual code while discussing your approach with the AI interviewer.
  • Duration: ~60 minutes (can run up to 90 minutes)
  • Format: One or more coding problems with real-time conversation
  • Focus areas: Code quality, problem-solving, algorithm design, and communication
  • Environment: Browser-based code editor with support for multiple languages

What’s Being Evaluated

AreaWhat the AI Looks For
CorrectnessDoes your code produce the right output?
Problem-solvingCan you break down the problem and identify an approach?
Code qualityIs your code clean, readable, and well-structured?
CommunicationCan you explain your approach and decisions as you code?
Edge casesDo you consider boundary conditions and error handling?
OptimizationCan you analyze and improve time/space complexity?
The AI evaluates your full approach — understanding the problem, planning a solution, coding it, and testing it. A working solution with clear reasoning scores better than a “perfect” solution you can’t explain.

How to Prepare

Before You Start

  • Know your language. Make sure you’re comfortable with the syntax and standard library of whichever language you plan to use.
  • Practice problem-solving out loud. The biggest difference from LeetCode-style prep is that you need to narrate as you go. Practice explaining your thought process while coding.
  • Review common patterns. Depending on the role level, brush up on arrays, strings, hash maps, trees, graphs, dynamic programming, or system design — whatever’s relevant.
  • Prepare your environment. Test your camera, mic, and internet. Make sure your browser supports the coding interface. See Technical Requirements.

During the Interview

  • Start with understanding. Read the problem carefully. Restate it in your own words. Ask clarifying questions before writing any code.
  • Plan before you code. Outline your approach verbally or in comments. Discuss time/space complexity upfront.
  • Talk as you code. Explain what you’re writing and why. “I’m using a hash map here because…” is exactly the kind of narration that helps.
  • Test your solution. Walk through your code with example inputs. Check edge cases. Don’t wait for the AI to find bugs.
  • Iterate. If your first approach works but isn’t optimal, discuss potential improvements even if you don’t have time to implement them.

What to Ask the AI

  • “Can I clarify the input/output format?”
  • “Are there constraints on time/space complexity I should aim for?”
  • “Can I assume the input is always valid, or should I handle errors?”
  • “Should I optimize for readability or performance?”
  • “Can I use [specific library/built-in function]?”
  • “Would you like me to walk through my test cases?”
Clarifying the problem before coding demonstrates maturity — senior engineers always scope before building. If you’re stuck, explain where you’re stuck. “I’m trying to figure out the right data structure for fast lookups here” shows you’re thinking, not frozen.

What NOT to Ask the AI

Don’t Try To…

  • Ask for hints or the solution. “Can you point me in the right direction?” — the AI won’t provide algorithmic hints.
  • Ask the AI to debug your code. The AI won’t tell you where the bug is. You’re expected to trace through and find it yourself.
  • Ask what test cases are being used. The evaluation criteria are set by the hiring team and not shared during the interview.
  • Request a different problem. The problem set is curated for the role. The AI cannot swap questions.
  • Ask for your score. Performance feedback goes to the hiring team, not to you during the interview.

Things That Don’t Help

  • Coding in silence — the AI can’t evaluate your thought process if you don’t share it
  • Writing code without a plan and then trying to fix it retroactively
  • Over-engineering the solution when a simpler approach works
  • Focusing only on getting the right answer without considering code quality or edge cases
  • Asking if the AI has “seen this problem before” or trying to figure out the problem source
The code interview rewards clear thinking as much as clean code. Talk through your approach, write readable solutions, and test thoroughly.
