Someone else here already pointed out the problem with that approach: After the second or third candidate, the interviewer is very familiar with the problem and may become unfairly judgemental with later candidates if they don't immediately see "the obvious".

How would you run a project like this? People come and go. People do a one-time contribution and then you never hear from them again. People work on a project for years and then just go silent. Honestly, credit where credit is due, but how is a project like this supposed to manage this?
AmigaOS supported both. Each drive and in addition each medium had it's own name. If GAMEDISK was in floppy 0, you could reference it either as DF0: or as GAMEDISK:
