The full bank is $39, one-time (no subscription). Pre-orders open when payments go live. Enter your email in the form above and we’ll notify you by email as soon as you can pre-order — it’s the same form that sends your free sample chapter.
Delivery timing: pre-orders open when payments go live. The full bank ships when all 100+ questions are complete; once you’ve pre-ordered, we’ll email your download link as soon as it ships. The 30-day refund window runs from your payment date, so it covers the wait.
Your sample chapter is ready
Read it in the browser, or download it. This is a genuine subset of the full bank — the same question and answer style.
This is a dev preview: the sample appears on the page instead of by email. Once the support email service is live, it will be sent to your address.
What’s inside the full bank
- 100+ real-style interview questions, organized into the five areas candidates report seeing: SQL & Databases, Statistics (including A/B testing), Case Studies, Behavioral (STAR), and Python & Tools.
- A structured model answer for every question — the approach, the key points a strong answer covers, and what the question is testing.
- Likely follow-up questions for each topic, so you can practice the second round of a conversation, not just the first answer.
- Formats that work for study: downloadable PDF and Markdown, plus the site itself as a browsable reference.
- Your own pace, your own schedule — no sessions to book, no subscription that renews.
Questions are written in a real style based on patterns candidates report; they are not attributed to any company, and nothing here claims to be “from” any employer.

- Study and practice. Work through the questions by category, rewrite the model answers in your own words, and use the follow-ups to drill the second round.

Questions, answered honestly
Is this from any specific company?
No. The questions are written in a real style, based on the patterns candidates report seeing in their interviews. None of them are attributed to, or claimed from, any company.
Will this help me get the job?
It’s a study aid: it gives you realistic questions and structured model answers to practice against. We make no promise about job offers or salaries — that depends on the whole application process, not any single preparation material.
Do I have to subscribe?
No. You pay $39 once and keep the bank. Content updates on the same pages are covered by that one payment.
What’s your refund policy?
You can get a full refund within 30 days of payment: email prep.ventures.help@gmail.com and we will refund your $39 in full.
What do I actually receive?
A download link by email (PDF and Markdown) and the site as a browsable reference. The free sample chapter is a real subset of the full bank — the same question and answer style.
When will I get my download link?
We’ll email your download link as soon as the full bank ships. The full bank ships when all 100+ questions are complete — the first 40 are already written and we’re finishing the rest. Your one-time $39 covers the whole bank when it ships.
How is the free sample different from the full bank?
The sample is 7 questions across the main categories — enough to judge the style. The full bank is 100+ questions with model answers and follow-ups in each category.
Is your team human?
We’re a small team that uses AI assistance to build and write. We say so rather than hiding it. Support answers are signed “the PrepBank team (AI-assisted)”.
