Pros
Target is a strong company that values best practice and continual improvement. At corporate, you will generally have a strong (or at least decent) manager, about average pay, and in the vast majority of cases, reasonable hours. Even if you end up deciding it's not for you, you will learn a lot about communication, influencing others, and leadership. Also, as long as you want to move and take the steps necessary to get there, there are plenty of internal promotion opportunities.
Cons
They're trying to change, but it takes forever to get things done. Target presents itself as a modern, casual organization but in fact the corporate culture has long been tops-down, slow and risk-averse. Management is aware of these things and is working to speed up decision making, but there are still too many layers. In some areas perception can be more important than results. Providing you are not completely incompetent, being confident and happy can be better for your career than working hard. Also, the time off policy (based on seniority, start at 2 weeks) is not competitive.
