I interviewed once. The doctor interviewing explained the requirements. Then he said that he has accepted me as a volunteer and it was my turn as to whether I accept his requirements, which is minimum 1 full year of volunteering.

Spoke with manager about the position and my career goals. Fairly standard interview for a volunteer position, very laid back since it’s not paid work! We just had a brief chat and then went over what paperwork/testing was needed to work in the system. You will need to supply a current TB test before you’re allowed to start work which can be a pain to schedule, so I’d start on that ASAP so your start date doesn’t get delayed.
