Technical Screening (Coding) · 45 min · Software Engineer or Senior Software Engineer
This round typically involves a coding challenge, often conducted via a shared online editor. The interviewer will present a problem that requires the candidate to implement a solution using data structures and algorithms. The focus is on assessing the candidate's ability to translate a problem into working, efficient code and to articulate their thought process.
What they look for
Strong problem-solving skillsProficiency in at least one programming languageAbility to think critically and logicallyClear communication of technical concepts
Evaluation
Correctness of the solution
Efficiency of the solution (time and space complexity)
Clarity and organization of the code
Ability to explain the approach and trade-offs
Sample questions
Given a binary tree, invert the tree.
