Pros
The best reason to work at PGE are the people, friendly and welcoming culture and the benefits (excellent health coverage and fun wellness programs)! It's an environment that puts a lot of energy into training (depending on the department you are in) and pays well for the area (depending on who your manager is). There is also a pretty-much-guaranteed bonus every year.
Cons
The main challenge is the lack of understanding around career progression. Managers don't really justify how some people move around, are assigned good projects, why you may earn significantly below your peers (10-40% less) for the same work done. Bonuses are also a bit mysterious even though they act like the whole process is very transparent. The company doesn't deal with poor performers, so annual goals are laid out but there's no real penalty for not meeting goals. PGE has a lot of people on the brink of retirement and they're not ready to embrace a new generation of millennials that will make up their workforce. All of the positions they post internally require a lot of experience to move into. Those positions are usually filled with outside consultants that come in with highly negotiated and pricey salaries.
