WEEK 9: System Design Interviews

Week ZERO Video

System design interviews are now an integral part of the software engineering interview process — particularly if you are applying for a senior role. These interviews have a significant impact on your “hiring level.”

Learn distributed systems concepts like Cap Theorem, Consistency, Partitioning, Load-Balancing etc.

Look at the course Grokking the System Design Interview for more design interview practice.

As part of your System Design Interviews, you are asked to design a “web-scale” service. Interviewers are interested in evaluating your ability to describe the different parts of a scale-able service, such as:

  • How are web-servers load-balanced?
  • How are databases shared?
  • How are large files stored?
  • How is the network set up for redundancy and maximum throughput?

You’ll want to practice questions like:

  • Design Instagram
  • Design Facebook Newsfeed
  • Design Uber

Learning Objectives

  1. Again, consider the "where and how" aroud the work you want to do.
  2. Explore the world of "Manager Readmes"
  3. Consider the value of creating a "coworker readme"
  4. Consider the value of "coding retreat" career breaks
  5. Be aware of the high level strategies for a system design interview
