30-45 seconds per question
Up to 2 minutes per question
Every submission is routed to a regional human review pool by division. Reviewers are graduate recruiters working alongside line professionals (second-year Analysts, Associates, VPs), and each recording is typically watched by at least two independent reviewers scoring 1-5.
Invitation timing. The video interview is tied to your psychometric performance: if your Aon scores meet the division baseline, the system triggers an invitation, usually within 48 hours to 7 days of completing the tests.
Completion window. A strict 7-calendar-day (168-hour) hard expiry from the invitation timestamp; extensions are reserved for documented medical emergencies or platform outages.
Retake policy. A strict zero-retake policy: once recording starts you have one opportunity per question, with no option to delete, re-record or edit.
Volume context. The London office receives over 30,000 early-careers applications a year. The Aon tests filter out roughly 60%, leaving about 12,000 at the video stage, and only the top 12-15% of recorded submissions earn an Assessment Centre invite.
Recent changes. UBS historically used Sonru across EMEA and has since moved to standard asynchronous formats often built on HireVue frameworks. The evaluation policy is unchanged: UBS explicitly states humans, not AI, review and grade video submissions.
