Med

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.

    Data StructuresAlgorithmsTreesRecursion
  • Find the duplicate number in an array of n+1 integers where each integer is between 1 and n (inclusive).

Prep for this round

  1. 01Practice coding problems focusing on arrays, strings, linked lists, trees, graphs, and hash maps.
  2. 02Understand time and space complexity analysis (Big O notation).
  3. 03Be comfortable with recursion and iteration.
  4. 04Practice explaining your code and thought process out loud.

Common rejection reasons

  • ×Inability to solve coding problems within the given time.
  • ×Poor understanding of fundamental data structures and algorithms.
  • ×Inability to explain thought process clearly.
  • ×Code that is inefficient or contains bugs.
