  • "Thanks for the question! This is one of my favourite topics because it’s at the core of what we do as PMs DAILY: making the complex simple to drive alignment. I’ve got a structured way to approach this, and I’ll use it to explain payment aggregators - like Plaid - and how they enable Open Banking, with a twist about a technical hiccup I’ve seen in practice. Let’s dive in. I start by assessing the audience. Say I’m talking to a marketing manager at Transak - someone sharp but not techni"

Meeting Rooms II (https://www.lintcode.com/problem/919/?fromId=203&_from=collection) on Leetcode seems like the closest comparison, it's a premium question so I linked Lintcode. I'm assuming that we also need to just return the minimum number of cars used. You need to sort for the most optimal solution, so you're constrained by an O(nlogn) time complexity. So any sorting solution could work (using a heap, sorting the array input arra"
