Got to the System design, a web crawler, which I had studied for. It was a custom web crawler, you can submit a list of URLs (100 urls max) and it wound find all images in any pages associated with the urls. But, this was more of a code design. Didn't care about throughput, storage capacity, endpoint security, load balancing, or flow of data through the system. They gave 3 endpoints and wanted you to design the crawler itself, how would it crawl the pages, and find the images. More like psuedo coding, but with graphical boxes. Not what I was expecting or prepared for.
