What do you need to survive? Food, water, and shelter. If society collapsed how would you acquire those, and how would you stop others from stealing them from you? Answer those two questions and you'll have somewhere to start. If this ever did come to pass (which I think is highly unlikely) you'll want to be fit, strong, and intelligent. I don't expect "interviews" would ever be a thing, but who knows. Watch some horror movies, see how individuals join/form groups, and stop over-thinking!
