Pros
Global employer. Quality health, dental, vision, life AD&D insurance. Lots of opportunities to try different fields and live in different regions. However, most of those regions in the US are in the Midwest. Decent opportunities to move within the company, even moving between profit centers. It's a hit and miss as to which accounting departments are "good" departments. There are some amazing middle and lower level managers, and also some nightmarish ones. They encourage you to stay in your position for 18 months, so be aware. Decatur is a terribly disappointing city, but the cost of living can't be beat.
Cons
Con's? How about: Decatur IL. Visit the city before you accept the job. Also, accounting platforms are ancient and not integrated. You think you know Excel? Baby, you haven't seen Excel in action until you've seen ADM Excel. Don't expect top tier technology with this Ag giant. ADM is working on a project to update the old and non-integrated systems, but it's expected to take a decade... or more. It's a large company that touts innovation, but somehow on the ground level (at least in accounting where I have worked) management is very stuck in its old ways. Be prepared to be overworked with unimpressive pay. If you're in operations accounting you can kiss your family goodbye for a week because of the large amounts of OT you'll work each month end.
