Methodology

Claims about how trading firms interview are easy to make and hard to check. You should be skeptical of them, including ours. This page explains exactly where our firm content comes from, how we label its reliability, and what we refuse to do. The short version: every claim is sourced, every source type is shown, and anything we cannot back up is left out.

Where firm information comes from

Firm guides are built only from publicly available material: official company careers and interview-process pages, role descriptions and job postings, university job boards, public candidate-report aggregators, and established third-party interview guides.

How claims are labeled

Every interview round in a firm guide carries a source badge:

• Official: described by the firm itself (careers pages, role pages, job postings).
• Candidate-reported: drawn from public accounts by people who interviewed. Useful, but secondhand, so treat it as indicative rather than guaranteed.
• Official + candidate reports: official information supplemented with public accounts from candidates.
• Third-party guide: an editorial interview guide that does not expose a first-person candidate source. We keep useful detail from these guides separate from candidate-reported evidence.
• Candidate + third-party reports: direct candidate accounts and editorial guides describe the same round, with each contribution identified in the text.
• Official + third-party guide: a firm source supports the broad stage or context while an editorial guide supplies additional detail. It does not mean a candidate directly reported that detail.

Each guide also shows an overall source-confidence level and a last-reviewed date, plus a standing caveat that processes vary by role, office, and year. When our only basis for a claim is inference (for example, a prep recommendation derived from a firm's stated focus areas rather than a documented round), the prep path labels it as such.

How prep paths are generated

Firm prep paths follow one rule: nothing on a path may be made up. Every step is generated from a sourced claim about that firm, and each step shows its provenance (the confidence level and the sources behind it). If we lack evidence for a role at a firm, we say so and do not offer a path for it, rather than padding one out.

What firm tags on problems mean

When a problem is tagged with a firm (the "Asked at" label), it means that problem has been reported as a real question used in that firm's interviews. This is deliberate, and it is one of the main reasons to use QuantReady: a large share of our problems are the actual questions firms have asked. Those tags come from two public, checkable kinds of source: candidate accounts that describe interviews in public, and signed-in users who tell us, on the problem page, that they were asked a specific problem at a specific firm. User reports are shown as counts and reviewed before they change a tag. We build only from this public record and from what candidates volunteer to us; we never use anything confidential, NDA-bound, or leaked to us privately. We are progressively attaching an explicit source to every tag, and any tag we cannot stand behind gets removed.

Mock interviews and practice games

Firm-specific mock sessions select problems weighted by the topic emphasis recorded in that firm's guide. They simulate topic mix and time pressure; they are not replicas of any firm's actual process. The same rule applies to our practice games and assessment simulators: they are our own designs, and where one is modeled on a candidate-reported assessment format, the page says so and cites the firm guide it draws on. Score bars in games are our practice bars, never a firm's real cutoffs.

What we never do

• No fabricated testimonials, reviews, or outcomes. Outcomes we cite are real and anonymized at the request of the people involved.
• No confidential or NDA-bound material. The real interview questions we tag come from public candidate reports and from candidates who volunteer them, never from anything obtained in confidence.
• No claims of affiliation: QuantReady is not affiliated with, endorsed by, or sponsored by any firm we cover. Company names and trademarks belong to their owners.

Updates and corrections

Guides carry a last-reviewed date and are re-checked periodically against current public information. Interview processes change; if you interviewed recently and something here is out of date or wrong, we want to know. Tell us through the contact form or the firm-report button on any problem page, and we will review it against the sourcing standard above.
