Salary bands are tightly restricted, so there is no consequent capability built-in to earn salary upgrades - if you begin employment at a starting salary on the lower-end of the Grade rate (for example, Grade A salary band = 37, 500 - 42,000) you remain at that rate until you retire or leave.
Because of the slant of the interview questions and requirements, previous experience and qualifications are unlikely to get you very far, as HR is looking for the right answers, not the most qualified people.
My typical day began at about 06:30, and usually ended at about 19:30 (my actual hours of work were contracted to be 09:00 - 16:30 Mon-Fri), as i was required to perform disciplinary/grievance hearings etc. for people who worked alternating 12-hour shifts, so I had to wait most days until the evening shift came on so I could communicate with my teams. That meant my work week, instead of being 37.5 hours, was normally 56 to 60 hours.
I found the technical part of the job the most involving, as it meant I could actually carry out the functions listed in my employment contract, although very soon after I started, my own morale became pretty much non-existent.
The one thing I learned, too late, was not to express my opinions!
