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

Facebook Timeline Interview
Wes asks Kevin to design the Facebook/Twitter Timeline with an emphasis on scaling to a large number of users.I'd encourage you to pause where relevant to try to think through these designs yourself - it really helps the content sink in.Helpful LinksRabbitMQ quick start documentation - https://www.rabbitmq.com/getstarted.htmlApache Kafka introductinon - https://kafka.apache.org/intro

Customer Reviews
Very useful
Love this series. Hope more content gets added and more frequently. Probably worth bringing more engineers so we can get different perspectives.
Appreciate your effort...
I am preparing for system design interviews and was lost in plethora of information available but no one tells how to structure the response. This podcast is helping me with that including having to server lots of additional value. However, I'd love to see more episodes.
Dropbox
Content is great. However i usually don’t write a review but i wanted to write here one.
Kevin : has a very articulate and flawless voice.
Wes: sorry to say but voice is bit slurry and felt like very casual even if he is playing the part of interviewee, i can understand the solution is jot readymade and it’s more of a discussion between two parties.
I have to say i had to rewind my podcast and put focus when wes’s start speaking. I am not sure if it’s due to the mic adjustment or if it can be corrected at source.
Hope this feedback reached to wes and kevin.
