Everything you need

Everything between the resume and the offer.

Gap analysis + ATS score

See exactly how your resume stacks up against the JD — keyword matching, the gaps that cost you the match, and the rewrites that close them.

AI mock interviews

SQL, Python, ML theory, case study, behavioral & system design — with an in-browser code editor and an answer scored against a rubric, not a vibe.

Why not just ask an AI chatbot?

A chat window answers you. It doesn't prepare you.

General AI is genuinely good at explaining a concept. It just has no idea whether you're ready.

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 behavioural — each with its own rubric, tuned per role and company type.

Pricing

Less than the interview costs you.

An hour with an interview coach usually costs more than three months of Pro. Start free — the plan and your first mocks don't need a card.

Frequently asked questions

Is there a free trial?

Every account starts on the Free plan — 2 mock interviews and the core features, no card required. Upgrade whenever you're ready.

What happens when my Pro/Pro+ access expires?

Your account gracefully downgrades to Free — we never delete your data. Roadmaps, history and analytics stay intact; premium features just lock again until you renew.

Do you offer refunds?

Yes — a 7-day money-back guarantee on all paid plans and credit packs. Request it right from Settings → Payment history, or email support@dataprepai.org. Tried it and it wasn't for you? Full refund. The one exception: if you've already used up most of what you bought, we may reduce or decline it — the guarantee is for trying risk-free, not for free interviews.

Which roles does DataPrepAI support?

Data Analyst, Data Scientist, Data Engineer, ML Engineer, Analytics Engineer and BI Developer — every prompt and rubric is tuned for data interviews.

How are the mock interviews scored?

Each answer is evaluated on correctness, communication, structure and depth by AI, with specific improvement suggestions and model answers.

Is my resume data private?

Your resume and job descriptions are tied to your account and used solely to personalize your prep — never sold, and never used to train AI models. Uploaded files are kept in encrypted storage and deleted with your account. See the privacy policy for the full detail.
