Technical Coding Interview · 45 min · Software Engineer / Senior Software Engineer

This round focuses on assessing your core programming skills and problem-solving abilities. You will be given one or two coding problems to solve, typically involving data structures and algorithms. The interviewer will evaluate your ability to understand the problem, devise an efficient solution, write clean and correct code, and explain your thought process. Expect to discuss time and space complexity.

What they look for

A candidate who can translate a problem into working code.Someone who can explain their approach and reasoning.Attention to detail in code implementation.Ability to identify and discuss edge cases.

Evaluation

  • Coding proficiency
  • Problem-solving skills
  • Understanding of data structures and algorithms
  • Ability to write clean and maintainable code
  • 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.
