Pros
9/80 schedule, general great peers and coworkers. Engaging work, interesting industry, and even without drinking the kool-aid you can recognize the impact of your work on the economy and environment. High commitment to environmental safety and goals around clean energy (despite what some media may claim). Compensation and benefits are great, which is why they keep people for so long. Lots of opportunity to rotate and learn new skills if you're proactive and network effectively. 8% 401(k) match if you contribute 2%. Pension too, which is generally unheard of for non-gov't jobs.
Cons
Finance teams are slowly getting caught up with technology and advanced analytics, but a lot is lip-service and patting each other on the back for using the right buzzwords. The ranking and pay determination process is archaic, and 1-2 incompetent group or line-level leaders can derail a successful employee. Many folks at early-to-mid career looking for opportunities due to lack of direction and general micromanagement. Several outright bad managers whose behavior is ignored by higher-ups.
