Depending on which team you join, you may have some really nice co-workers. I had some good colleagues that I would love to work with again.
Someone once asked me why would I associate with a corporation with such negative reputation. If you didn't know about the negative publicity, do a search. Before you join this organization, make sure you are okay with the values this organization has.
Every month I heard a colleague or two left the organization. Some of the reasons were low pay, no growth opportunity, disagreement with management, burned out.
Frequent emergencies caused key individuals to drop everything and worked on the emergencies, sometimes during off business hours.
Different stakeholders had different demands, which increased difficulty to move an initiative forward. Many middle management were resistant to change. Combine this with bureaucratic processes and bad practices, projects were delayed for weeks to months.
