It's the same thing in FAANGs. The competition for the over-inflated salaries they offer is such that it's a matter of chance whether someone gets hired or not. You might as well invest your money at the blackjack table in your local casino.

Edit: as a personal recommendation, try not to start your comments with "lol". It makes the comment sound shallow and detracts from your point.

Having gone through the process and coaching a friend though it, it's as much of a crapshoot as studying for any standardized test (which is to say not at all). The things on the test are standard grad school ML stuff with a dash of systems engineering. You know what's not on this test though: peano axioms or set theory lol.

No, of course, but who said they were?

Also, I'm getting the feeling all the lols are meant to underline something clever and pointed, but I fail to see it. Can you clarify?
