Sent my CV, then Aon sent me to do assessment test including their situation-based test (how would you react in a different situation), then was invited to do an an initial competent-based interview with 2 HRs. Then after is an interview with Aon's local business leader.

Had to do an online asessment that tests your time management skills and how you prioritize tasks. Followed up by a recruiter screen interview and then two rounds of behavioral interviews with HR and directors of different departments you will rotate in.
