To all the commenters saying "stfu and stop whining": the thing you're missing is the false advertising on Google's part. Google doesn't tell you when you're going through their intense and selective recruiting process that your job is going to be crap.
Google managers like Paul Carff *specifically* make plans to dress up the job descriptions of what are essentially CSR positions, to lure top talent from top universities. Where they do mention CSR-type work, it's often called a "minor" or "infrequent" part of the job.
And regardless of the position, if you're accepting something on the order of 0.01 percent of applicants like Google is, and you're asking the kinds of quantitative+creative interview questions for which they're known, you are GOING to get a lot of intelligent, highly talented people. Lying to these people and putting them in dead-end positions is a recipe for disaster, which is why Google Support has such incredibly quick turnover.
You have to realize that high-caliber recent college grads are probably friends with lots of other high-caliber recent college grads. This means that, when they get lured across the country to the Bay and end up in a crappy CSR job they didn't sign up for, while their friends get much more appropriate roles in companies like Bain, Salesforce, and McKinsey, they aren't happy about it — and they shouldn't be.
