I agree. I think that's at play here even if Google or their hiring department will never admit it. Having a long, drawn-out process will dissuade a lot of older workers with families who may not have time to invest in practicing for the interviews or scheduling them all, again maybe something Google benefits from if they want to have young workers who are more easily shaped and eager to devote more time to their jobs.
