Provenance · Updated May 11, 2026

Where the practice bank comes from.

We don't paywall the question bank. We don't fabricate answers. We don't claim "millions of users" without being able to count them. What we do is publish how the practice bank is built — by lane, source type, source name, and active count.

15,176 active questions across 63 sources, organized into 4 provenance lanes. Each row below has a link to the canonical upstream where applicable.

Takedown + correction policy

If you're the rights-holder of any source above and want a question removed or re-attributed, we respond within 24 hours. Email hello@instantinterviewer.com with the source name and the specific question(s) — or a blanket removal request if you'd rather not enumerate.

Lane B community-report sources are paraphrased into archetype form before they enter the public bank — facts are preserved, the original wording is rewritten. Lane A (attributed) sources keep their wording verbatim with a visible source link inline.
