How we research career guidance
How we use official labor data, engineering documentation and employer hiring guidance, with explicit limits and reproducible teaching exercises.
Match the source to the question
Government occupational statistics support claims about a defined labor market. Official engineering documentation supports technical explanations. An employer's hiring page describes that employer's published process, not every hiring process. We link sources near substantive claims and list them below each guide.
Read labor data precisely
Salary articles identify occupation, country, currency and measurement period. A median is not a starting salary or an offer promise. Employment projections are not a count of current vacancies. Replacement openings and employment growth are different measures. See the salary guide and labor-data reading method.
Make examples reproducible
Our JavaScript exercise is an original teaching example, not a reported interview question. Its downloadable tests cover stable order, duplicate handling, input validation and preservation of the input array. The example does not benchmark programming languages or simulate an employer assessment.
Keep recommendations conditional
Role titles and hiring stages vary. We state assumptions and suggest questions to verify with a real employer. We do not invent placement rates, candidate success stories, internal hiring data or professional credentials. A learning plan is an editorial framework, not a guaranteed route to employment.
Useful original materials
Use the career evidence worksheet or resume checklist. Diagrams illustrate the article's reasoning and do not represent measured outcomes. Read the editorial policy, correction process and publisher directory.
