  • For the graph question, the candidate wrote a brute force code to find the distance from one node to every other node. It passed the given 3 tests but failed hidden ones. After spending some time, the candidate asked to move ahead.
  • For the design question, the candidate suggested using Async processing to ensure that the cart updates immediately when an item is added. They also mentioned using caching and a master-slave architecture to improve read speeds from the database.
