Domain Knowledge

Typical domain knowledge questions look like

  • What happens when you open an URL in a browser?
  • What is a Virtual DOM?
  • What happens when you execute docker run command?
  • Explain L4 vs L7 load balancer.

Some companies think that “Domain Knowledge Interview” could test both your depth and breadth of knowledge. I tend to enjoy this kind of question personally because they are just fun to do. Most of the time you are ok to say you don’t know to move to the next question because no one knows everything !!!

Again, the key to becoming good at practice is to mix both passive and active learning. This has a lot to do with how our brains work.

Passive Learning

Here are some of the best resources (mostly books) I can find. Not only do they help you to prepare for domain knowledge interviews, but they also help you to become a better software engineer.

Active Learning

Unlike system design open-ended discussion, domain knowledge always has at least one answer. Mainly depends on how much you know and how well you could describe. Finding a peer to help you could also be helpful, but most of the time, you know yourself the best, right?
