The sorting continues in college; SAT scores are most predictive for the first year, before less-capable students switch out of the hard majors. My guess is that nearly all of the engineers Google hires score very highly, and in that sense the SAT is indeed predictive of success there (since you can take it in middle/high school), but they might have determined that discriminating on the high end between differences of <1 SD (about the validity between retakes) might not tell them much.
