How to tell whether an interview question bank is trustworthy

Judge a question bank on what it shows you before you pay, not on how many questions it claims. The three checks that separate the serious ones fastest: does an individual question carry a date, does the site say where the question came from, and can you read enough without an account to tell.

Last reviewed on October 18, 2026.

Seven checks, and what each one tells you

What to check	A good sign	A warning sign
Dates on individual questions	Each question says when it was last reported, so you can tell a question from last month from one that has been circulating for five years.	A date only on the page or the article title — "Updated 2026" at the top of a list whose entries carry no dates of their own.
Stated sourcing	The site says where questions come from: candidate reports, named public sources, its own authors, or some mix, and distinguishes between them.	"Real questions from real candidates" with nothing behind it. If a platform cannot say how a question reached it, you cannot check it.
What is readable before paying	Question titles, companies, difficulty and dates are public, so you can judge coverage for your target company before subscribing.	Nothing visible until you pay or sign up. You are being asked to take the catalogue on trust.
What "practice" actually means	The site is specific: does it run your code, against which test cases, in which languages, and is there a reference solution.	"Built-in editor" doing the work of implying a judge. A text box you can type into is not the same as running hidden tests, and the two are often described in the same breath.
How the price is presented	A plain price, and a renewal you can reason about. Discounts that end when they say they end.	A permanent countdown. While researching these comparisons we found sites showing a crossed-out price, a large percentage off and a timer — on an ordinary day, with the timer resetting. A sale that never ends is just the price.
What the headline number counts	A count you can decompose: how many for the company you care about, how recent, how many are locked.	A single large number with no denominator. 'Questions from 200 companies' may be two questions each for most of them, including yours.
Whether limits are stated	The platform says which companies and roles it covers thinly, and what it does not do.	A platform that is best at everything. Comparison pages written by a vendor — this one included — should say where someone else is the better choice.

Where Hack2Hire itself falls short

Coverage is uneven: some companies have deep, recently-reported sets and others have a handful of older entries. Check your company before subscribing, not after.
Last-reported dates depend on reports reaching us. A quiet date means we have not seen a recent report, not that the company stopped asking the question.
Our catalogue is smaller than crowdsourced banks by design, because review is the bottleneck. If you want maximum breadth, that is a real reason to look elsewhere.
We are not an independent reviewer of this market. Every comparison page on this site is written by us.
Our forum is small next to the large public communities, so for discussion volume those are still the better place.

Questions worth asking any platform, including this one

Where did this specific question come from, and when was it last reported?
What can I read about my target company without paying?
If I write code here, what actually runs — and in which languages is there a reference solution?
What does this platform say it is not good at?

Questions people ask

Can I tell whether an interview question is real?

Not with certainty from a single source, and anyone who tells you otherwise is overselling. What you can do is look for a date, a stated interview round, and a second independent report of the same question. Two first-hand accounts from different candidates in the same quarter is about as strong as public evidence gets.

How do I spot AI-generated question lists?

They tend to be plausible, fluent, undated and uncorroborated, and the questions often read like textbook exercises rather than something shaped by a particular team. The reliable test is not style but provenance: does the page say where each question came from, and can you find it anywhere else?

Is a bigger question bank a better one?

Only if the extra questions are for your company and are accurate. Beyond that, a larger catalogue mainly costs you time deciding what to skip. Depth for the five companies you are interviewing with beats breadth across two hundred you are not.

Should I trust this page, given who wrote it?

Treat it as a checklist, not a verdict. Every check here can be run against Hack2Hire too, and we have listed our own weak points above so you can. If a check we propose is one we fail, that is useful information about us.
