Great work/life balance but not particularly motivating and enriching. - Senior Product Manager American Express Employee Review

Work gets done by who you know and how strong your internal network is - not exactly meritocratic. 80% time spent just trying to convince others that it's the right thing to do , 20% time actually spend doing it. Do not expect to do something earth shattering or extremely dynamic - Amex does do cool stuff but it pails compared to the number of employees it has employed and unless you get into the right group you might not get the opportunity. If you come from a startup you will do in 8 months what it might take 2 months to do in a startup. I would recommend that you evaluate the Job role and prospect of the group you are potentially getting hiring into much more than American Express as a whole. What applies to one team in the company might not apply to another it varies widely. I wouldn't turn down a good offer in a group that has good prospects and is doing some really interesting stuff.
