What is System Design?

System design is the process of defining different attributes to meet the requirements of complex systems such as:

  • architecture
  • product design
  • modules
  • interfaces
  • data

And beyond.

The goal is to understand component parts and how they interact with one another.

Take this literal example to showcase the importance of clarifying the specifications of a system:

Who cares about system design?

If you want to work at a FAANG as a software engineer, system design knowledge is critical. Interviewers are very likely to ask you system design questions at places like Google, Amazon and Microsoft.
