An anonymous reader writes: Maybe you've been intrigued about working at Google, but unfortunately you slept through some of those economics classes way back in college. And you wouldn't know how to begin figuring out how many fish there are in the Great Lakes. Relax; Google has decided that GPA's and test scores are pretty much useless for evaluating candidates, except (as a weak indicator) for fresh college graduates. And they've apparently retired brain teasers as an interview screening device. SVP Laszlo Beck admitted to the New York Times that an internal evaluation of the effectiveness of its interview process produced sobering results: 'We looked at tens of thousands of interviews, and everyone who had done the interviews and what they scored the candidate, and how that person ultimately performed in their job. We found zero relationship. It’s a complete random mess'. This sounds similar to criticism of Google's hiring process occasionally levied by outsiders. Beck says Google also isn't convinced of the efficacy of big data in judging the merits of employees either for individual contributor or leadership roles, although they haven't given up on it either.
