AI ▸
Good start. Before writing code, what data structure are you thinking of using, and why?
YOU ▸
I'd use a hash map to store each number and its index as I iterate.
AI ▸
Correct. What's the time and space complexity of that approach?

Features

Built around real interview mechanics

Every feature exists because real technical interviews demand it — including the ones that test how well you work with AI.

[01]

Live AI Interviewer

Back-and-forth conversation. The AI probes your reasoning, challenges assumptions, and guides you with hints, just like a human interviewer in a real loop.

[02]

Honest Scored Feedback

Every session ends with a report scoring communication, problem-solving, and code quality on a 1–10 scale with written explanations.

[03]

Full Code Editor

Write real code in Python, JavaScript, Java, or C++ inside a Monaco editor with syntax highlighting and a resizable split-pane layout.

[04]

Two Problem Tracks

20 curated coding problems for traditional interview prep, plus 10 GenAI Coding assessments built around scenarios where AI produces plausible-but-flawed output. Practice both, because both matter.

Timed 45-Minute Sessions

Practice under real interview time constraints. A live countdown keeps you on pace, and your time management is reflected in your final score.

Session History

Every completed session is saved so you can review scores, re-read feedback, and see exactly where you've improved over time.

Why Placed

The gap between practice and performance

Most platforms only test what you know. Placed tests how you think, how you communicate, and how well you work with AI — because all three matter now.

---traditional_practice.md
  • -Solve problems in silence with no one to talk to
  • -No feedback until you look up the answer
  • -Pass/fail verdict with no explanation
  • -Never tested on communication or reasoning
  • -Doesn't replicate real interview pressure
  • -Zero coverage of AI collaboration skills

  • +AI interviewer that asks follow-up questions in real time
  • +Socratic hints when you're stuck, not just the answer
  • +Scored feedback on communication, logic, and code quality
  • +Replicates the pressure of a real 45-minute technical round
  • +Session history so you can track improvement over time

GenAI Coding

The skill every engineer needs. Almost no one is training for it.

AI-assisted development is already the norm at most engineering teams. The engineers who stand out aren't the ones who use AI the most — they're the ones who know when to trust it, when to question it, and how to take full ownership of the output.

prompt_quality

Prompt Quality

Writing precise, well-constrained prompts that produce useful output — not just asking AI to "write this function for me" and hoping for the best.

output_validation

Output Validation

Catching logic errors, off-by-one mistakes, and subtle edge case failures in AI-generated code before it goes anywhere near production.

human_judgment

Human Judgment

Knowing when to use, modify, or discard AI output entirely — and making that call quickly without second-guessing every line.

accountability

Accountability

Understanding that you own the code. AI is a tool, not a co-author who shares the blame when something breaks in production.
