Frequently asked questions
Honest answers, including the ones you should ask.
Is this a job guarantee?
No. This is a study aid — a question bank with model answers for practicing. We make no promise about job offers, hiring outcomes, or salary. Interview results depend on many things outside any study material.
Are these real interview questions?
They are written in a real style: realistic, based on the patterns and topics candidates report in interviews. No question is attributed to any company, and no company name appears anywhere in the bank. Think of them as realistic practice questions, not leaked questions from any specific employer.
Is this tax, legal, or financial advice?
No. This is an interview-prep study aid. It is not tax advice, legal advice, or financial advice of any kind. (It does not even try to be — it covers interview topics: SQL, statistics, behavioral, Python and tools.)
What format is the download?
Two files: PDF and Markdown, delivered as a download link by email after payment. The site itself also works as a browsable reference. The PDF is for reading/printing; the Markdown is for editing or importing into your own notes. No app or account is required — just a PDF reader or any text editor.
How much, and is it a subscription?
$39, one-time. No subscription, no renewal. You pay once and keep the bank. Content updates to the questions and answers on the same page are covered by that one payment.
How does the free sample chapter work?
Enter your email in the form on the page and we email you the sample chapter: 7 real-style Q&As with model answers across the main categories. It is a genuine subset of the full bank, not filler — enough to judge the style before you decide. We use your email only for the free sample chapter, to let you know when pre-orders open, and — once you pre-order — your download link. See our privacy policy.
How is the full bank organized?
100+ questions in the five categories candidates report seeing in data-analyst interviews: SQL & Databases, Statistics (including A/B testing), Case Studies, Behavioral (STAR), and Python & Tools. Every question comes with a structured model answer, what the question is probing, and likely follow-up questions.
What happens after I pay?
You get an email with your download link — it is a one-time payment and delivery is a download, so there is no shipping, no wait, no account to create. If something does not arrive or the link does not work, email us at prep.ventures.help@gmail.com and we will sort it out.
Who made this?
The PrepBank team (AI-assisted) — a small team that works with AI assistance and says so plainly. We are a new product with no customer base yet; we would rather tell you that than pretend otherwise.
What if I want my money back?
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. The window runs from your payment date, so it covers the pre-order wait — if the bank has not shipped yet and you email us within those 30 days, you can still cancel. We do not promise a specific processing time. Your refund is handled by a person (the owner), not processed automatically, and a person will follow up with you directly about it.
Can I use this if I’m interviewing for other analyst roles?
Yes — the bank is organized around the topics that recur across data-analyst interviews generally, not a specific job. It will help you with the kinds of questions most likely to appear in that role family.
How do I contact support?
Email prep.ventures.help@gmail.com. We answer people who write to us first; we never email you first (except your sample chapter and download link). We reply as the PrepBank team (AI-assisted).
