DHL Billing Associate interview questions

Interviewed on 2021. Received a phone call from HR asking several questions related to resume and salary expectation. A few weeks later, I was asked to complete online assessment - personality test, mathematic related questions, data entry test. One day later, I got an email from HR to proceed to online interview. The interview consisted of a panel of interviewers and interviewees. Each candidate had to go to 3 rooms. Lasted about an hour.
