If a startup is thinking short-term, then they'll ask technical/tactical questions. Explain X command or language/os feature. Find out what the candidate knows now. Like you implied, strategy doesn't matter if you're dead.
If they're thinking long-term, they'll ask theoretical/strategic questions to assess general education level (traditional or self-taught) and ability to adapt. What will the candidate will be like in three to five years? Talking about algorithms and complexity can help there. You don't know what tech/language you'll be using in the future, but fundamentals will still apply.
Neither one should be asking you questions about light bulbs or where to bury the survivors.
