That's technically a memorization test or a trivia test, because its really easy if you remember the trick, and a total PITA if you don't remember the trick. If I recall correctly the trick is something along the lines of pouring a full 5L into a empty 3L and when the 3L is full there's 2L left in the 5L, so then you dump out the 3L then pour the 2L in the 5L into the 3L such that the 3L contains 2L of H2O, and then refill the 5L and pour the 5L into the 2/3 full 3L till its full such that about 4L remain in the 5L bottle. Ta Da, I've just proven I can memorize meaningless trivia, does that mean I am now a C++ developer or whatever they were interviewing for?

If you started life as a chemist this is kind of a lab joke as in its funny but if anyone in the lab tried something this wasteful of time and product or risky of contamination if you reuse the product, they're too stupid/lazy to work in your lab. The correct answer is supposed to be walk to the stockroom and ask for a 4L container.

Its about as useful as a practical programming test as asking who won the 1984 baseball world series, in other words a complete waste of time.

Fizzbuzz at least is an excellent test of the modulus operator (oh boy is that ever useful to me on a daily basis LOL) and a so so test of control block and conditional knowledge which is actually useful on a daily basis.
