As added context for other folks considering whether or not to apply, in my case Rachel replied back adding: "I think we're looking for folks with more small team experience, specifically evidence of loving & thriving in a fast-paced startup with ambiguous problem solving challenges and lots of ownership."
I'm not entirely sure what that means (I applied with startup experience at a ~100 headcount company), but it might indicate preference is for folks coming from a sub-100 headcount stage of startups.
