Technical Coding Interview · 45 min · Software Engineer

This round is a technical coding interview, typically conducted via a shared online editor. You will be asked to solve one or two coding problems that test your understanding of data structures and algorithms. The interviewer will assess your problem-solving approach, coding style, and ability to explain your solution.

What they look for

Clear thinking process.Ability to translate requirements into code.Basic understanding of time/space complexity.Willingness to ask clarifying questions.

Evaluation

  • Problem-solving approach
  • Coding ability
  • Understanding of data structures and algorithms
  • Communication of thought process

Sample questions

  • Given an array of integers, return indices of the two numbers such that they add up to a specific target.
