Pros
It's rare to find a brand that has so much brand recognition and heritage in American fashion. The employee discount is also great. Since Gap owns a tons of stores, there are tons of opportunities and challenges the company faces which makes for an exciting job. If you are interested in fashion and want to be in San Francisco, this is a great place to start.
Cons
Given poor performance for an extended period of time, morale is low and turnover is high, which means less retention of knowledge and inexperienced employees. The organization is very functional siloed, so different functional teams working in the same brand do not communicate or coordinate enough. There is also poor portfolio management, as all three brands have some overlap.
