> The philosophy at Google is that it's better to filter out 3 good engineers than to let in a bad one.
Google's problem nowadays is that they have such strict standards only for grunt developers, but not for management. In fact, it looks like that it's more like opposite, i.e. it's better letting in/promoting 3 bad managers/directors than 1 good one.
This is sadly true, but even more true for PMs, the average engineering skill required to be inside the organization went down. When Eric Schmidt was selected as the CEO, having a strong engineering background was a requirement for him, and he was great at connecting with engineers inside the organization (probably not that great with connecting with sales, they had to accept that Google was an engineering driven organization in the past, now it's a mix).
