Vantaggi
Unlike many places, senior management here are genuinely nice people. Nice people really do finish first here. There is a big coaching and feedback culture here. Nationwide has a sterling reputation in Central Ohio due to its generosity to various charities. You will be expected to contribute to various charitable campaigns (particularly United Way, which is a really big deal). But this is a good thing. You will see a lot of people who wear Nationwide logo shirts out in public. People are proud to work here.
Svantaggi
The silo mentality is a reality. This is a big company, and it feels like it. Information sharing between departments is nonexistent. Some departments hoard information, but this happens in almost every corporation.
