Avantages
Decent company, good products. Great for entry level work experience or just mindless hours to earn some cash. Professional, well established company with some benefits if you decide to stay around long enough. If you choose a specialty area you can get some good related training/education.
Inconvénients
Like any job, be prepared for ego's and fiefdoms within any store and work-center. If you get along with others easily you'll do fine. Used to have decent benefits but has taken many cost cutting measures out on employees, particularly hourly workers. Can differ between stores but seem overly PC and in my experience many executive/managerial members seemed constantly afraid for their jobs, especially ones that came up through the ranks vs. the new college grad hires at their first career type jobs. Remember it's retail so be prepared to not have any life around holidays or weekends and be prepared to beg for work hours during the slow times.
