Very professional. The interviewer had to fill in a 2 sided A4 questionnaire and wrote down what I said. The interview and health and safety form took about an hour which is longer than I expected which meant I started my 4 hour work trial shift slightly after the start, and finished slightly more tired. I had to wait in a reception where there was CCTV, a noticeboard, a receptionist, and some free white bread rolls. Lots of them!
