Practice interviews that
actually give you feedback.
Five adaptive questions for your target role, scored like a real interviewer would — with specific feedback on each answer and a full debrief at the end. Not a quiz. Not a flashcard deck.
Example feedback
Question asked
Walk me through how you'd debug a memory leak in a Node.js production app.
Answer score
72/100What worked
Correctly mentioned heap profiling and process.memoryUsage(). Showed familiarity with Node's event loop model.
Room to improve
Didn't mention specific tools (clinic.js, v8-profiler). Answer would be stronger with a concrete step-by-step approach rather than a list of things to check.
Three modes
Pick the interview type you're preparing for.
Behavioral
Past experience, how you handled situations, teamwork and conflict.
Technical
Coding concepts, data structures, language and framework knowledge.
System Design
Architecture decisions, trade-offs, and how you think about scale.
How it works
Four steps. One session.
Pick a role and type
Name the role you're preparing for and choose behavioral, technical, or system design.
Answer five questions
Each question is generated based on your role and what you've already answered — no two sessions are identical.
Get feedback on each answer
Every answer is scored 0–100 with specific strengths and improvements — not a vague grade.
Read your overall debrief
A synthesized wrap-up of the full session: your clearest strength, what to focus on improving, and an honest overall read.
