## Round 1: Data Structures and Algorithms
**Type:** Technical Interview (Coding) · **Difficulty:** Medium · **Duration:** 45 min
Coding round to assess fundamental programming skills and problem-solving.
This round focuses on assessing your fundamental programming skills. You will be given one or two coding problems to solve. The interviewer will evaluate your ability to understand the problem, devise an efficient algorithm, write clean and correct code, and explain your thought process. Expect questions on data structures, algorithms, and basic problem-solving.
**Interviewers look for:** Ability to translate a problem into a working code solution.; Understanding of time and space complexity.; Clean and well-structured code.; Logical thinking and debugging skills.
**Evaluation criteria:** Correctness of the solution.; Efficiency of the algorithm (time and space complexity).; Code quality (readability, maintainability, style).; Problem-solving approach and communication.
**Common rejection reasons:** Inability to articulate thought process clearly.; Lack of fundamental knowledge in data structures or algorithms.; Code with significant bugs or inefficiencies.; Poor problem-solving approach.
## Questions

- Reverse a linked list.
- Find the kth smallest element in a binary search tree.
- Implement a function to check if a string is a palindrome.
