I applied in-person. The process took 3 weeks. I interviewed at G4S (Belfast, Northern Ireland) in Feb 2016
Interview
On the day the process was a bit amateur. the people in the office didn't seem to be very friendly they would tend to avoid eye contact so you were made to feel a bit unwelcome. it was also quite a long time that I had to wait on the interviewer to actually arrive, that made me feel uneasy.
