Yeah I mean the vacuum landfill thing is stupid. The point was never to try to trip people up, there's no wrong answer (or question), just find out if they could recognize ambuiguity. "Let's try to estimate the amount of pet food sold each year in the USA." -> "Dogs and cats too?", "In terms of dollars or pounds of food?" type of stuff. This was for analyst roles - basically your whole job would be something similar to this where you're asked ambiguous questions and you need to translate that into a semi-rigorous analysis, infer intent, etc. I hate to say it but if you didn't realize that going into the interview, you were probably not a good fit as an analyst in the first place!
