Capita interview questions

The interview was very simple, online, and fairly casual but I discovered in the middle of it that I needed to have my passport to hand which hadn't been conveyed in advance. I then had to go and find my passport which I thought would have seemed unprofessional but I guess they didn't mind as I got the job. On acceptance of the job I was given a work email to access workday and found a message there telling me to have my passport ready. Somewhere I couldn't access before accepting the job and being given a work email.
