I believe anaskar is saying that, for the one instance they've seen, Google either takes on the entire team or no one, and they don't do the normal Google interview.
And he may be right for n=1, but I know of n>1 instances where he's incorrect and whole teams were not taken. I even know of one instance where the CEO/founder was non-technical and they refused to allow him to remain in charge of the product post-acquisition. The direct of product, who was a Google SWE before the acquisition, took over.
