Result: WaitList
Difficulty: Hard

Interview Process

The interview process consisted of an online application followed by an onsite interview. The onsite included a variety of technical questions and design problems.

Technical Questions

  • Coding: Lazy array
  • Algorithm: Traffic problem, initially asked about the time complexity of DFS and BFS. After writing BFS four times, I was asked to optimize it to a single execution, which I did not complete.
  • System Design: Designed a system for Amazon, covering functional and non-functional requirements, estimation, schema and API design, and discussed scaling, fault tolerance, and consistency.

Tips & Insights

Be prepared for multiple rounds of coding and system design questions. Focus on optimizing algorithms and understanding the principles of system design.
