Frequently asked questions

A worked question bank for DevOps, SRE and platform engineering interviews. Each topic runs easy to expert, and every question is answered in five parts: the short version, the approach, the full working, the follow-up the panel asks next, and the reply that sounds right and loses the round.

Premium is a single payment, US$25 by credit card or PayPal, or ₹2,000 by UPI, card or netbanking. It unlocks every answer across every topic for six months, including whatever is added during that window, and it does not auto-renew.

No. Paying unlocks the whole bank instantly, so every sale is final. The free tier exists precisely so that is a fair deal: read the open answers in whichever topic you care about, in full, and decide from the actual writing rather than from a description of it. The Terms carry the exact wording. If something has gone wrong on our side, write in before assuming the answer is no. A person reads everything that arrives.

Yes, and you only have to ask. If your loop lands just past the six months, write in and we will push your access out so it covers the interview. No charge, no form. We would rather you walked in ready than watched a clock.

A person, and usually the same day. The contact page is the quickest route. Billing that went wrong, access that did not open, an answer you think is mistaken, a question you think is missing: all of it is worth sending, and none of it is too small to bother with.

Every question title is public. The first 18 answers in each topic open without an account. Free Google sign-in opens the first 28 per topic and saves your progress and bookmarks.

You drop back to the free tier. Progress, bookmarks and the open answers all stay. Buying another six months is a thing you do deliberately, never something that happens to you.

Yes, and a card needs no PayPal account. Every payment is handled by Razorpay or PayPal end to end. Card and UPI details never reach this site and are never stored by it, and access opens the moment the provider confirms the money.

Yes, and it earns you something. Submit one while signed in, and if it gets published it carries your @handle and adds a day of full access to your account automatically. The Submit a Question page is where to do it.

We use AI assistance to draft and revise material. Content passes automated checks for structure, writing rules, links and diagrams before release. Those checks do not establish that every technical claim is correct; review coverage varies across the library. Our editorial policy explains attribution, sources and corrections. Read the open answers to judge whether the explanations meet your needs before buying access.

No. Company names and marks appear only to say which hiring loops a question is modelled on. There is no affiliation, endorsement or partnership with any of them, and every trademark belongs to its owner.

The Contact page has a form that comes straight to us. Most messages get a reply inside two working days.
