New improved company culture emerging
Pros
Transunion is undergoing major changes, for the better. When I started 3 years ago, it was the typical big company culture with a lot of life-timers, boring environment, no fun, waterfall process, COBOL, and no innovation. The new management team (ie Jim Peck) is changing that. We are now much more agile and nimble (but still a lot of room for improvement), Big Data, new vibrant office environment, and lots of new eager employees. Culture is becoming very open, and honest feedback expected. We are moving from IBM to Google (figuratively speaking). Lots of changes. If you are thinking about joining TU, make sure to talk to someone who has been here lately and witnessed the change.
Cons
TU is an aircraft carrier, not a swift boat. Changing course (culture, beliefs, technology) takes time, but there are still many pockets of "old TU" resisting the change. Not everyone is on board with new direction and energy.
