Ask HN: Can anyone give me information on Amazon's Application Platform Team?

I or perhaps somebody I know was contacted by a recruiter for their Application Platform Team. Can any current or former Amazon employees (or friends of) give me any information about the job/team/platform that I might not get from HR? Is it interesting work? Challenging? How much bureaucracy? I've heard a lot of pros and a lot of cons about work at Amazon. Obviously a very subjective matter... just looking for opinions.
