## Round 1: Coding Round 1
**Type:** Data Structures and Algorithms Interview · **Difficulty:** Medium · **Duration:** 45 min
Coding round to assess problem-solving and implementation skills using data structures and algorithms.
This round focuses on your core programming skills. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will assess your ability to understand the problem, devise an efficient solution, and implement it correctly in code. They will also evaluate your thought process, communication during problem-solving, and how you handle edge cases and constraints.
**Interviewers look for:** Strong grasp of fundamental algorithms and data structures.; Ability to write clean, efficient, and bug-free code.; Logical thinking and systematic approach to problem-solving.; Understanding of time and space complexity.
**Evaluation criteria:** Correctness of the solution.; Efficiency of the solution (time and space complexity).; Code quality, readability, and maintainability.; Problem-solving approach and ability to break down problems.
**Common rejection reasons:** Inability to articulate thought process.; Poor understanding of fundamental data structures and algorithms.; Inefficient or incorrect code implementation.; Lack of attention to edge cases and constraints.
## Questions

- Given an array of integers, return indices of the two numbers such that they add up to a specific target.
- Implement a function to reverse a linked list.
- Find the kth smallest element in a binary search tree.

## Preparation tips

- Practice coding problems on platforms like LeetCode, HackerRank.
