## Round 1: Coding Round
**Type:** Technical Interview - Data Structures and Algorithms · **Difficulty:** Medium · **Duration:** 45 min
Assess core programming skills through coding challenges.
This round focuses on assessing your fundamental programming skills. You will be asked to solve coding problems that test your knowledge of data structures, algorithms, and your ability to write clean, efficient, and correct code. Expect questions related to arrays, strings, linked lists, trees, graphs, sorting, searching, and dynamic programming. You'll need to explain your thought process and justify your solution's complexity.
**Interviewers look for:** Strong grasp of DSA concepts.; Ability to translate problem statements into working code.; Logical thinking and systematic approach to problem-solving.; Clean and efficient coding practices.
**Evaluation criteria:** Correctness of code; Efficiency of solution (time and space complexity); Code readability and structure; Problem-solving approach
**Common rejection reasons:** Inability to solve basic coding problems.; Poor understanding of fundamental data structures and algorithms.; Lack of clarity in explaining code logic.; Negative attitude towards feedback.
## Questions
