I sometimes ask questions and get 'What would you do if there was no one to ask?' and 'What would you do if there was no Google?' and I would like to understand this. Should I have everything rote memorized? Should everything I do be a bespoke solution?
The latter is a gentler way of saying, "no, I want your solution to this trivial problem".
The former is a question about your work process; for instance, if they say, "ok, so build Twitter" and you respond rationally with, "what of Twitter should I build?", they're probably looking for how you operate in an environment with underspecified work. It might be a good idea to talk about how you'd defend your decisions to draw the boundaries of the problem; why you chose to ignore e.g. streaming updates or following; &c.
