Short answers to the questions readers ask most often. If yours is not here, send it in — the ones that keep coming up get added.
What does “what work involves” mean on this site?
It means the practical content of a job: the tasks that fill the week, the conditions you do them in, what you need to get hired, what it pays, and where it leads. A guide is meant to answer “would I actually want to do this every day?” rather than “am I qualified?”
Where do your pay figures come from?
We start with official statistics — for US roles, the Bureau of Labor Statistics’ Occupational Outlook Handbook — then cross-check against current job postings in several metro areas. Each range states its source, its geography, and the month it was checked. How we research a guide explains the process in full.
Why do two salary sites give such different numbers for the same job?
Usually because they are measuring different populations. Government medians cover everyone in the occupation, including people with twenty years’ service; self-reported salary sites skew toward people who choose to report, often in tech and in cities; job-posting averages reflect advertised ranges rather than what is actually paid. None is wrong. They answer different questions, which is why we publish a range and label where it came from.
How often are guides updated?
Pay and entry requirements are re-checked at least once every twelve months, and more often in fields where licensing or pay moves quickly. Each page shows the date it was last reviewed.
Are your guides written by AI?
Software helps with drafting, structuring, and keeping the format consistent across dozens of guides. It is not a source: it does not produce quotations, people, interviews, or statistics. Every factual claim is checked by an editor against the sources cited on the page before publication. The editorial policy sets out the boundary.
Do you accept payment to feature a job or an employer?
No. Employers, recruiters, and training providers cannot pay to be covered, to be ranked, or to change how a role is described. Some outbound links are affiliate links, which are disclosed on the page they appear on and do not affect an assessment — see the affiliate disclosure.
Can you help me find a job or review my resume?
No. We are an editorial team, not a careers service, and we do not refer people to employers. What we can do is describe the work accurately enough that you can decide whether to apply.
Do you cover jobs outside the United States?
Some, but the pay and licensing figures are most reliable for the US, because that is where the public data is consistent and comparable. Where a guide covers a role that is licensed differently in other countries, it says which jurisdictions we checked. Treat figures from another country as indicative, not authoritative.
How do I report a mistake?
Email 269659595@qq.com with the page URL, the sentence, and what it should say. Corrections are prioritised over everything else, and the page is updated with a note of what changed.
Can I republish or quote your content?
Short quotations with attribution and a link are fine. Republishing a whole guide, mirroring the site, or using the content for commercial training requires written permission — see the terms of service.
