Pros
Pearson is a company with a strong commitment to its mission of "helping people get on with their lives through education." Its commitment to living its values (brave, imaginative, decent) and to social responsibility, diversity and people makes it a company with a conscience. Nice to see in this day-and-age. Pearson's successful global brands (Financial Times, Penguin, Pearson Education) provide multiple opportunities for career development, whether in a single division or across Pearson companies and the countries in which it operates. While not perfect, it is company whose sr. leadership is committed to continuous improvement, and market place success. Dame Marjorie Scardino is a visionary and inspirational head.
Cons
There are a lot of smart, driven and clever people who work at Pearson. That's a big draw for most who work there, but prospective employees should be aware that they will be challenged in their jobs and will need to work hard and be open to constantly learning new things.
