Editorial approach
How we distinguish primary sources, original practice, real PDF samples and claims that still need evidence.
On this page
Sources have a defined job
Sources support the factual claims they can establish. A standards publication can explain a framework or assessment method; it cannot prove that a particular employer asks our fictional interview question. An advertised course price does not establish its sales or hiring results.
Where a lesson uses external guidance, it links to the relevant source and limits the claim to the material inspected. Dated employer examples are examples of those postings at that time. Candidates should check the current posting before applying.
Examples are original teaching material
Our companies, records and candidate examples are fictional unless explicitly identified otherwise. Exercises may contain a fictional procedure so there is a concrete criterion to apply. That procedure is not presented as an industry requirement.
Worked answers explain the reasoning and its limits. Another answer can be defensible when it accounts for the evidence and states its assumptions. Qualitative practice prompts are not psychometric assessments or predictions of interview performance.
Samples come from the actual books
Public book previews are extracted from the corresponding PDF edition. The reader also offers selectable text. Product pages explain which chapters the preview covers and which later material remains outside it.
Companion counts include editable blanks and completed references. They are not counts of independent projects. Current prices, package contents and purchase availability are shown on each product page.
Experience and review claims
We do not invent practitioner credentials, testimonials, employer endorsements or customer outcomes. No independent practitioner review of these books is claimed. A fictional sample of written resume feedback demonstrates format and scope; it is not a completed customer engagement.
For your own application, keep direct work, support work and educational projects distinguishable. See how to label a project.
Revisions and corrections
An updated date identifies an editorial revision, not continuous verification of every linked website. New information should change the relevant conclusion and leave its scope clear. In the books, follow-up records deliberately require revisions to earlier answers.
Use the support address on contact and availability to report a correction. Include the page URL and the statement you want us to review. Do not send private resumes, customer records or confidential employer evidence.
