Grade C

Why this grade This listing scored 64/100, which is a C. It lost the most ground on pay transparency. See the breakdown

Freshness 15 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
Remote clarity 15 / 15 Whether "remote" means anywhere, or is quietly restricted to one country.
Description depth 14 / 20 How much the posting actually says about the work, measured in characters of real text.
Pay transparency 12 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.
Corroboration 5 / 10 Whether more than one source carries this listing.
Role specificity 3 / 10 Whether the listing is tagged well enough to tell what the role actually is.

Every figure above is arithmetic over the posting itself — its salary field, its text, its age, its tags and how many sources carry it. How the grades work →
