Pros
Dealing with intellectual professionals to solve complicated problems. Never a dull moment, lots of challenges to find solutions for. Innovative spirit encouraged. Good infrastructure, office facilities and services. Decent opportunity to change job roles every 18 months or so, pending favorable performance reviews.
Cons
Cost cutting has deeply impacted all parts of the firm. More experienced (yes, more costly) professionals are being let go or leaving (to find better opportunities). Most teams are stretched, taking on more responsibilities than should be done by the few people, can cause points of tension and stress in a crisis situation. Younger workers are brought in, but these professional lack the experience or the ability to multitask and get things done sooner. The work demands are heavy, can bring about higher burn rate. A professional here will do the job of 2-3 people at another comparable firm. The joke that one works at GS from 9 to 5, has been interpreted as working "9 AM to 5 AM (the next day)".
