But the brain teaser is also just an exercise in trying to get a discussion going. Okay so how could I possibly memorise the volume of a 747 and a ping pong ball, and even if you give me that it's a decent amount of complexity to calculate.

But are we accounting for their comfort and making sure they all have TV screens? Do we have to account for FAA regulations? Is it okay if some of the ping pong balls get damaged as we try to fill the aircraft? Are we completely emptying the aircraft or leaving the seats in? Does the plane still have to fly and if so which areas have to be accessible in FAA regulations? What is the weight of a ping pong ball and if you have enough of them does that come close to the allowed take-off weights?

Some of how you respond to these is an indication of how you will respond to challenges and frustrations in the team.

This was always the claim, yes.

And much like how these days people complain about getting rejected for slipping up on a leetcode problem in a minor way, back then there were plenty of stories of interviewers treating these problems as a black & white problem where you were expected to just know the answer.

To be clear, the problem wasn't the question. It was the interviewer asking the question.
