One thing I'd like to know about is how google deals with declines in productivity. Undoubtedly, their hiring process gets them highly qualified individuals, at least initially. But over time, there has to be people who become lazy and take advantage of their good graces. And it would be expected that as people age they start a family and their work priorities may take a back seat.<p>Is there some kind of process, ala Jack Welch, where people are ranked and the bottom 10% are removed? How does google deal with under-performers?
