Hmm it's these open questions that are the ones to be careful of. Ideally in a Lyft interview you'd have to demonstrate the entire gamut of Product skills; from clarifying and scoping, to problem identification and prioritization, to customer personas, big-picture thinking and solutions, and finally also make sure to cover execution and metrics related stuff. Might be worth considering a mock with one of the Lyft PM experts on Prepfully, they've got folks who are actually are at or have been at Lyft so they really put you through the paces - and you get an authentic experience. prepfully.com/practice-interviews
