Technical Screening · 45 min · Software Engineer

This initial technical screening focuses on your core computer science knowledge. You will be asked questions related to data structures, algorithms, and problem-solving. The interviewer will assess your ability to analyze problems, devise efficient solutions, and translate those solutions into working code. Expect to write code, either on a whiteboard or in a shared editor.

What they look for

Solid grasp of DSA.Ability to write clean, working code.Clear communication of thought process.Consideration of time and space complexity.

Evaluation

  • Understanding of fundamental data structures and algorithms.
  • Ability to apply algorithms to solve problems.
  • Code clarity and efficiency.
  • Problem-solving approach and logical thinking.

Sample questions

  • Given an array of integers, find the contiguous subarray with the largest sum.

    ArrayDynamic Programming

  • Implement a function to reverse a linked list.

    Linked ListPointers

  • Find the kth smallest element in an unsorted array.
