Hard

System Design · 60 min · Senior Software Engineer / Tech Lead

This round focuses on your ability to design complex, scalable, and reliable systems. You will be presented with a high-level problem statement and expected to break it down, discuss various design options, justify your choices, and consider potential bottlenecks and failure modes. Expect questions on distributed systems, databases, caching, messaging queues, and API design.

What they look for

A structured approach to problem-solving.Deep understanding of distributed systems.Ability to make sound technical decisions.Clear communication of complex ideas.

Evaluation

  • Clarity of thought process.
  • Ability to handle ambiguity.
  • Depth of knowledge in system design.
  • Consideration of edge cases and failure scenarios.
  • Communication of trade-offs.

Sample questions

  • Design a system like Instagram.
