Pros
Flexible work schedule, good benefits
Cons
Any kind of promotion or job change requires you apply thru USA jobs - essentially a computer based system that selects qualified candidates based on multiple choice answers. Many applicants who exaggerate their knowledge thru these answers are ‘referred’ for promotion consideration. The IRS has become a very unrewarding place to work - I don’t recommend it. Hard work and knowledge are not valued. They only want to promote people who play the game. IRS is in trouble going forward - everyone who actually knows what they are doing are retiring/leaving - the people left are inexperienced newbies who have been promoted only because they want to be managers. IRS is literally becoming a bunch of inexperienced managers managing nobody.
