Pros

Good work life balance - including telecommuting and flex time Good social environment receptive to family, with no problems with family members visiting office

Cons

Bad telecommuting policy - open to interpretation and not really conductive of management goals (i.e. why were they enforcing things the way they were?) Bad/deceptive salary - they justified based on industry average and claimed to want to sit on the 60th percentile. However, their figure used was inc super, whereas the salary data was a mix of inc and exc super - inference is that they were actually positioned at 45 - 55th percentile but tricking employees to think they were at 60th.

Fun work environment, if slightly uninspiring work.

Pros

Depending on the team little to moderate stress levels. Professional managers, realistic deadlines and interesting clients. Short to medium term projects, never assigned to boring projects for too long. Nice team culture.

Cons

Compensation not nearly as good as in banks and competitors, who keep poaching talented developers. Johannesburg's team not growing fast enough / stagnating. No drive to innovate, since clients (banks) don't desire cutting-edge technology. Little contact with software once it's been shipped to a client. More strict and boring processes put in place by ACI Worldwide Inc.
