Big company, too big to fail, too big to succeed - both as a company, and for the individual employees. - Analyst Citi Employee Review

Big company, you can easily gotten lost if you are not aggressive. Like everyone else said, you are just a number - or as they put it, a P & L. In business, it's about how much you can bring in. In back office operations and technology, it's all about how many people you "manage". Huge disparity in pay scales depending on your group - in fact, there is no "Citigroup" culture, it's all about the culture of whatever group you wound up in.
