The number is step one. Getting the offer is step two.
Every administrative assistant job in London has three gates between you and an offer at that level:
- The ATS screens against the keywords the recruiter wrote into the job ad. If your CV doesn’t mirror them, you’re filtered out before a human sees it.
- The recruiter scans the top third of your CV for about 7 seconds. If your most relevant evidence isn’t there, you’re dropped.
- The hiring manager asks why you, what you’d do in the first 90 days, and how you map to their team. If the cover letter and interview brief don’t answer those, you’re a no.
TAILOR optimises your whole application against each specific administrative assistant job ad. One click on a posting, one analysis, six tailored documents that clear all three gates, maximising your position and putting you in front of the hiring manager. The one who actually decides.

A note on the figures
ASHE estimates are based on a 1% sample of HMRC PAYE records. Smaller occupation × region cells have wider confidence intervals; ONS suppresses figures it judges too imprecise to publish (you’ll see — in our tables where ONS marked the cell "x").
Provisional release. Revised 2025 figures land in November 2026. TAILOR refreshes the dataset annually when the revised release lands.
