Easy

Technical Screening · 45 min · Technical Screener

This initial technical screening round focuses on assessing your foundational programming skills. You will be asked to solve one or two coding problems, typically involving basic data structures and algorithms. The interviewer will evaluate your problem-solving approach, coding style, and ability to explain your logic.

What they look for

Ability to translate a problem into code.Understanding of basic time and space complexity.Clear communication of approach.

Evaluation

  • Correctness of code
  • Efficiency of solution
  • Clarity of thought process
  • Basic understanding of data structures and algorithms

Sample questions

  • Write a function to find the factorial of a number.

    RecursionIteration
  • Given an array of integers, return indices of the two numbers such that they add up to a specific target.

    ArraysHash Maps
  • Explain the concept of Big O notation.

    AlgorithmsComplexity

Prep for this round

  1. 01Practice coding problems on platforms like LeetCode (Easy/Medium).
  2. 02Be comfortable explaining your code line by line.
  3. 03Review basic data structures (arrays, linked lists, stacks, queues) and algorithms (sorting, searching).

Common rejection reasons
