Frequently asked questions

A curated interview-prep library for AI, ML, and GenAI engineering and adjacent roles. Each topic is a journey ordered from fundamentals to the staff-level questions that decide offers, with answers written to the standard of someone who has sat on both sides of these loops.

Premium is a one-time payment (₹2,000 in India via UPI/cards on Razorpay, or US$25 via PayPal) that unlocks every answer across all topics for six months, including any new questions added during that window. It does not auto-renew.

Start here is the shortlist: the highest-leverage questions across every topic, and the right first stop if you have an interview this week. Questions is the full bank, grouped into 11 topics and sequenced inside each one so the foundations come before the questions that build on them. Most of the bank sits at medium and hard, because that is where these loops actually run. Concepts is the curriculum: the underlying ideas explained in order, each closing with a self-check drill, for when you want to learn a subject rather than drill questions on it. Companies is per-employer prep: the real loop, stage by stage, for 40 companies. Role guide answers what the job actually is, day to day, and what it pays. Most people go Start here, then Questions, and dip into Concepts wherever an answer exposes a gap.

No. Premium unlocks digital content immediately, so all sales are final. That is exactly why we keep a generous free tier: work through the free answers in any topic first and judge the depth for yourself before paying. See the Terms for the full policy.

The full question list is public across every topic. Without an account you get the first 10 complete answers in each topic; sign in free with Google and that becomes the first 20, plus progress tracking, bookmarks, and mastery. Across all 11 topics that is more than 200 complete answers before you pay anything.

Your account returns to the free tier. You keep your progress, bookmarks, and free answers, and you can buy another six months whenever you want. It never renews automatically.

Yes. Payments run through Razorpay and PayPal. We never see or store your card or UPI details; access is granted the moment the provider confirms your payment.

Yes, and we reward it. If you submit a question while signed in and we publish it, it carries your @handle and you get +1 day of full access added to your account automatically. Submit one on the Submit a Question page.

No. Every answer is held to a written editorial standard and a content linter that rejects generic filler, and each carries the insider texture interviewers actually screen for. The free answers are deliberately the strongest content on the site so you can verify this before paying.

No. Company names and logos are shown only to describe the kinds of loops our questions are modeled on. We are not affiliated with, endorsed by, or partnered with any of them, and all trademarks belong to their owners.
