Software Engineers Wes Moncrief and Kevin Li discuss aspects of the system design interview, as well as related topics in designing large and interesting software architectures. If you're new here, I'd suggest starting with the episode "Facebook Timeline Interview". I'll also note that our first few episodes had lower quality audio than our subsequent episodes.We'd love to hear any listener feedback - email us at thesystemdesignpodcast@gmail.com
