Throughout this series, we’ve tackled multiple LeetCode problems, and attempted to explain most of the concepts and approaches needed to solve them. In addition to this we covered behavioral interview questions and mentioned that nailing an interview isn’t only about writing optimal code. Now, on top of these two big topics: solving problems optimally, and answering behavioral questions, we have a third one and it is: System Design. As preparation for system design interviews, in the previous video of this series, we covered scaling and load balancing. In this video, we go over two additional topics: Databases and Caching.
