NS counts towards experience in Legal Service.
Which department of Legal Service are you applying for? Generally for 2-3 yrs experience, they will hire as Grade 6A or 6B, which are the starting level grades.
Pay wise - I don’t know what the rates now are. But it was around 5k many years ago when I joined. Legal service ordinarily pays about 16-18 months in a year, so take that into account.
Increments are good. There are substantial increases with promotions.
Career progression depends, frankly, on attitude and aptitude. Legal service generally far more meritocratic than private practice (where things like connections may make a difference).
Exit options - no clue. Haven’t felt the need to leave, so haven’t checked. Generally, resignation rate is v Low. But the people who’ve left have found pretty solid jobs.
