RevenueCat wants strong software engineers, really aligned towards the mission and values. It's very obvious through everyone you talk to how passionate they all are about the product. To me personally, it felt like every interview, while technical or non, is also a culture fit interview. You should learn about the product & values going in, and make sure you're aligned. To hold that high bar, I went through quite a few rounds - Initial Culture / Alignment interview with an Engineering Manager - Frontend-focused interview, implementing some components and talking through - Backend-focused interview, not Leetcode style, but more practical yet still testing DS & algorithms knowledge - Interview Panel - System Design. This is probably one of my favorite system design rounds ever, much more practical - Culture / Values interview. - Founder interview It's maybe a bit more process then standard, but when I see how RevenueCat seems to have managed to preserve great culture/passion, I think this is the tradeoff you have to make sometimes to have that.
