Pros
Equifax has a solid reputation with its clients and is the leading repository of decision information. It has made great strides in improving the employee experience by offering work flexibility options such as work-from-home and flexible hours. It has a good matching for the 401K program and does offer health insurance although it it expensive in my opinion. Work locations include gyms and reasonable cafeterias.
Kontras
The annual employee review system is not one of the best. There is a quota system whereby only a small percentage is allowed to be rated as "Excels" and regardless of how hard you work you will probably be in the "achieves" category. This is especially true if you are a junior person in a smaller department where the senior team members are entrenched and management doesn't want to lose them. The dress code, although not as stringent as other companies could be loosened for those who spend their entire work life in a cubicle out of the eye of any outside entities. Many times managers are provided gushing kudos and rewards for work that the rank and file accomplished, in spite of the manager's lack of knowledge about what the employees really do. I have seen a lot of turnover of great folks because of the perception that they aren't appreciated yet have unreasonable pressure from managers so the managers can shine.
