For a long time google had cachet as the most engineering friendly big tech firm (which was mostly deserved) and also the place with the highest level of talent (which is more team dependent but also somewhat deserved). You might end up working on ads or some other inane thing, but at least your engineer coworkers would be really good. They're still riding that wave to some degree because they haven't scared away all their top talent yet.
