Unrivalled opportunities to work at the heart of Government, changing the law as well as advising on it, often in scenarios that cannot be found elsewhere
Cons
Pay is poor and getting worse, office environment is as bad as it gets (think call centre style), not enough attention is given to training and career progression is vague and erratic
Great diversity of work and most of it is genuinely interesting. You're encouraged to move about regularly so you can experience for the full breadth of public law.
Cons
You won't ever earn as much as friends in the private sector and you'll be looked down upon by self-employed barristers.
