## Round 1: Coding Challenge
**Type:** Technical Screening (Coding) · **Difficulty:** Easy · **Duration:** 45 min
Coding challenge to assess basic problem-solving and programming skills.
This round is a technical screening focused on fundamental programming skills. You will be asked to solve one or two coding problems, typically involving arrays, strings, or basic algorithms. The interviewer will assess your ability to write clean, efficient code and explain your logic clearly. Expect questions on data structures and algorithms.
**Interviewers look for:** Clear understanding of basic programming concepts.; Ability to translate a problem into code.; Logical thinking and step-by-step problem-solving.; Ability to communicate their thought process effectively.
**Evaluation criteria:** Problem-solving ability; Coding proficiency; Algorithmic thinking; Communication of approach
**Common rejection reasons:** Inability to solve basic coding problems.; Poor explanation of thought process.; Lack of understanding of fundamental data structures/algorithms.; Poor communication skills.
## Questions

- Given an array of integers, return indices of the two numbers such that they add up to a specific target.
- Write a function to check if a string is a palindrome.

## Preparation tips

- Practice coding problems on platforms like LeetCode (Easy/Medium).
