What you get
Built for how engineers actually prep
Every feature is designed for data and AI engineering interviews, not generic behavioral prep.
Rubric-grounded scoring
Every question maps to a human-written rubric with anti-inflation caps. Factual errors cap at 4. Definitions-only caps at 5. Score 8+ requires real depth.
Rubric checkpoints
See exactly which concepts you hit and which ones you missed. No vague feedback. The engine names the gap.
Probing follow-ups
Real interviewers don't stop at your first answer. Get 3 follow-ups per question that dig into the weakest part of your response.
Stronger version
Every feedback card shows what a strong answer looks like, grounded in the rubric you were graded against, not a generic template.
Seniority-calibrated
Junior, Mid, Senior, Staff. The rubric strictness adjusts to your target level so you know if you're actually ready for the role you want.
Cross-session tracking
Watch your skill curve across topics over time. See where you're improving and which areas still need work.
How it works
Three layers, zero inflation
Not a chatbot with a prompt. A calibrated evaluation pipeline.
Question engine
Pulls from 530+ curated questions or generates role-specific questions from your resume and JD, tagged by topic, subtopic, and difficulty.
Evaluation engine
Scores against a human-written rubric with anti-inflation guardrails. Every dimension is scored independently and the verdict is calibrated to seniority.
Coaching engine
Generates annotated feedback, a stronger answer, and targeted follow-ups based on exactly which rubric checkpoints you missed.
Your next interviewer won’t grade on a curve
Practice with the same rigor you’ll face in the real thing.
