We do daily shifts with a follow the sun rotation, makes it easier to handle persistent commitments and ensures a bad week doesn't all land on the same person.
Most don’t even like the question. For them such questions are red flags or the candidate is not “motivated enough”. Rarely some even have follow the sun policy. They might have one in their HQ, true for a lot of US/EU firms, but their offices in a developing country like India - it’s always something on the lines of “oh, engineers here take full ownership; they are the owners”.
Also, I have seen — 2-3 days rotation with follow the sun is best, week long or longer being worst.
Then there are companies where it could be forever on-call with no follow the sun - e.g. Amazon, Uber (in India at least). That’s another world altogether.
Cooperatives really should be more common.
It's just rhetorical trickery.
