I’ve interviewed once with Google, didn’t make it so take that grain of salt in my comment:

Every time I’ve met with ex-FAANG types in the last decade (and I’ve got dozens of anecdotes) I felt like I was talking with a Wolf of Wallstreet bro stereotype. Complete lack of humility / big ego.

The big name and big money attracts a certain personality type.

I realize full well this is broad strokes and not all are bad, but there’s a bias in the population pool.
