## Round 1: Coding Round
**Type:** Technical Interview (Coding) · **Difficulty:** Easy · **Duration:** 45 min
Assess fundamental coding skills with data structures and algorithms problems.
This round focuses on assessing your fundamental programming skills. You will be asked to solve coding problems that test your knowledge of data structures and algorithms. The interviewer will evaluate your approach to problem-solving, the efficiency of your code, and your ability to explain your thought process clearly.
**Interviewers look for:** Basic coding ability; Understanding of fundamental algorithms; Logical thinking
**Evaluation criteria:** Correctness of code; Efficiency of solution (time and space complexity); Clarity of explanation; Problem-solving approach
**Common rejection reasons:** Inability to solve basic coding problems.; Poor understanding of fundamental data structures.; Lack of clarity in explaining thought process.
## 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 check if a binary tree is a Binary Search Tree (BST).

## Preparation tips

- Practice coding problems on platforms like LeetCode (Easy/Medium).
- Understand the time and space complexity of your solutions.
