This initial round focuses on assessing your foundational computer science knowledge. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will evaluate your ability to write clean, efficient code and explain your thought process.

What they look for

Clean and efficient code.Logical thinking process.Ability to break down problems.Basic understanding of time and space complexity.

Evaluation

  • Basic coding proficiency.
  • Understanding of fundamental data structures and algorithms.
  • Problem-solving approach.

Sample questions

  • Given an array of integers, find the contiguous subarray with the largest sum.
