Vantaggi
Pearson is a great organization to work for. Management is outstanding, exec leadership are involved and aware of goings-on and interact with front-line employees frequently. There are several visionary folks throughout the organization and while they are loosely organized (see: Yammer), they are able to help shape and shift the organization. I would heartiliy recommend Pearson!
Svantaggi
There are challenges, as there are in any large organization, particularly around innovation and challenging the status quo. It's not quite the monolith that IBM or other Blue Chip organizations are, but there are times that change comes slowly (if at all). Internal shared services are less than ideal. The green initiatives have not yet reached HR/payroll services and certainly not accounts payable.
