Given one of our video pages https://www.wired.com/video, replace the “MORE” button with infinite scroll, so when a user scrolls down on the page, they get the next 12 most-recent videos. Please share your screen to write notes as we talk through your solution.

• Please describe your implementation assuming this is a Ruby on Rails application.
• Talk through all the parts of the application stack.
• Feel free to focus on the parts of the stack where you’re most comfortable.

Problem 1: Implement a Secret Santa Matching Algorithm



The algorithm should take a set of names and return a set of pairs of names chosen randomly as follows:



• Each person’s name is put in “a hat”.

• Each person randomly draws a name from a hat, and becomes that person’s Secret Santa (they’ll buy an anonymous gift for that person)

• If a person draws their own name, they draw again.

Problem 2: Add a search feature to a comic book reading application.

Pretend we have an application that allows users to log in and read comic books. Think of it as a mix between netflix and kindle. Users can search for content, add to a reading list, share with friends, etc. The stack is a react client with an Express api server, and your DB of choice. How would you add a search feature to this app?
