Features

Everything between the resume and the offer.

Gap analysis + ATS score

See how your resume scores against the job description: the keywords that match, the gaps that cost you the interview, and the rewrites that close them.

AI mock interviews

SQL, Python, ML theory, case study, behavioral and system design, with an in-browser code editor and every round scored against a rubric.

Readiness score per skill

Your scored rounds become a readiness score per skill, measured against the level a strong candidate for your role is expected to hit, so you always know what to practice next.

Why not a chatbot, a course, or a question bank?

A chat window answers you. A course teaches you. Neither tells you if you're ready.

General AI is genuinely good at explaining a concept, and a good course teaches it properly. Neither has any idea whether you'd pass on Thursday.

Answers the question you asked

Scores how you answered it

Every mock is graded on correctness, communication, structure and depth, with model answers and the specific things to fix.

Forgets you between sessions

Builds on every session

Your resume, target role and interview history carry forward, so each mock starts from what you've already shown.

Can't tell you if you're ready

Measures it, skill by skill

A readiness score per skill, against the level a strong candidate for your role is expected to hit, so you know what's actually short.

Doesn't know how data interviews run

Built around the real rounds

SQL, ML theory, case study, system design and behavioral, each with its own rubric, tuned per role and company type.

A course teaches the topic

Tests whether you can do it under questioning

The explanation lives on your roadmap at the point you need it. The mock round is where you find out if it stuck, with follow-ups.

A question bank shows you what gets asked

Tells you which of it you're short on

Your resume gaps and your scored rounds decide what you practice next, so the plan is built from what you're missing, not a syllabus.

Pricing

Less than the interview costs you.
