Technical Screening · 45 min · Software Engineer / Senior Software Engineer

This initial technical round focuses on assessing your fundamental programming skills. You will be asked to solve coding problems that test your knowledge of data structures and algorithms. The interviewer will evaluate your ability to write clean, efficient, and correct code, as well as your approach to problem-solving and your ability to communicate your thought process effectively. Be prepared to discuss time and space complexity.

What they look for

Clean, efficient, and correct codeLogical and structured approach to problem-solvingClear communication of thought processAbility to handle follow-up questions and edge cases

Evaluation

  • Coding proficiency
  • Understanding of data structures and algorithms
  • Problem-solving approach
  • Ability to explain code and logic

Sample questions

  • Given a binary tree, invert the tree.
