- 1. Company description. Written by InterviewOS from Inferact's public materials and press coverage; facts are checked against the sources below.
- 2. Weekly counts. A count is the number of listings the pipeline saw for the first time in that week. Weeks begin Monday; the onboarding week is excluded from the scale and every average.
- 3. Live counts. Deduplicated live listings observed daily on Inferact's own hiring system; last check September 12, 2026. Stale and syndicated posts on aggregator sites are not counted.
- 4. Posted pay. Ranges extracted from the text of Inferact's own listings; a range appears only when the employer printed one. Extraction is still rolling out, so this table can lag the board.
