I guarantee that some of this is un-processed bitterness over my eventual rejection after 3 or 4 rounds of interviewing. :-D This particular FAANG does have a poor track record on products that have any kind of real-world component. I tend to approach products from an issue-spotting, pre-mortem perspective that's focused on mitigating roadblocks. I could tell where I was falling short was that they wanted to hear about how it would scale to billions of users rather than overcoming the 0-to-1, 1-to-10 barriers that I was focused on. The response was always that they could skip those steps because of their massive resources.
