A classically terrible interview question. Solving riddles in realtime is almost never a real job skill. _Maybe_ in an incident, but you’d be relying on tooling and experience, not an intern. Same with leetcode at startups. It makes no sense. You’re almost certainly not going to do algorithms work. It’s only relevant if you’re looking for people willing to grind bullshit, which is certainly some jobs, but, again, you…
The speed with which I can remember some obscure AIX partitioning-related fact during an incident, for example, is orders of magnitude faster than the speed with which I would figure out which of 12 marbles is slightly heavier than the others.
Now you have my attention. I'd love to read about some of these trivia.
