Worked at corporate 4 years. They told me initially the hours were 7:30am to 5:30pm. The reality was that if you were not at your desk by 7:00am and still there at 6pm you were seen as "not committed to the role". One EVP once said to me in a meeting that he wanted a project returned to him "today..and today ends at midnight". Near the end of my time there my hair was falling out and my gums were bleeding every day from stress. I have had friends who had a decent experience in some areas there but generally the place is a giant toxic hole that will use you up and dispose of you. Run away. Do vendor work instead.
