"On the board now" counts postings that are neither taken down nor past their advertised closing date, whenever they were posted — it is a figure about today, not about 2026-W44. Weekly figures cover the last completed ISO week: the week in progress is always partial, and reporting it would show a crash every Monday. Data is refreshed daily, so it lags the live market by up to 24h.
The last 12 completed weeks. A week at zero is a real zero — either a quiet market or a pipeline that did not run, and data freshness tells you which.
Seniority is inferred from title, position level and stated years — read it as a band, not as a job ladder.
MCF's arrangement field mostly covers scheduling, not location — only Telecommuting and Flexi-Place count as Remote/Hybrid, so postings with no location signal are Unknown.
Contract and part-time work is a different search from permanent — worth knowing how much of the board is which before reading the pay figures, which do not separate them.
Entry-level means at most 2 years required, or an Intern/Junior title with no stated requirement. 12 of 88 postings in 2026-W44 qualified, and 49 are on the board right now. Counts, not shares: "12 postings this week" is something you can act on.
