Make sure that security is your career choice, incorporate fitness into your daily routine and engage in activities to keep you alert at all times. I say this because, many banks in Southern Africa use G4S as their main security hub and as such, most of the robberies incurred are on G4S personnel and trucks. As for the salary, it depends on the country you reside in as well as your qualifications and hired post. The team, itself, shows a lot of support although there is a deep competitive nature among the workforce. All in all, it is not a shabby job and company to work for.
