#TfL has released data on the August 2025 recruitment drive for Customer Service Assistant 2 (CSA2) roles on the London Underground. As of 13 November 2025, a total of 15,919 applicants entered the competition. Of these, 6,192 progressed past the initial online assessment. The subsequent AC1 written and data‑interpretation test was passed by 1,224 candidates, although the full assessment process remains ongoing. In the next stage, the AC2 role‑play interview saw 437 candidates succeed, again with further evaluation pending. Finally, 269 applicants cleared the AC2 Scenario‑Based Interview (SBI). The figures illustrate the attrition at each stage of the selection funnel, highlighting the competitive nature of the CSA2 recruitment.
