The marketplace is too scattered to understand, seeing as its common knowledge that most devs can't fizzbuzz on command, and also everyone knows all interviews are piles of buzzwords surrounded by infinite whiteboard algo discussions.
Given that disorder in the marketplace, you might be worried they're asking for an entire tech startup, but they might be happy with little more than a personal fizzbuzz hello-world analogy. If your employer were jerks enough to demand ownership of your fizzbuzz-alike, you could write another in a day or two.
Something more like a weekly homework assignment from school, and less like a PHD thesis.
