## Round 1: Data Structures and Algorithms
**Type:** Technical Interview (Coding) · **Difficulty:** Easy-Medium · **Duration:** 45 min
Coding challenge focusing on data structures and algorithms.
This round typically involves a coding challenge, often conducted on a shared online editor. The interviewer will present a problem, and the candidate is expected to write code to solve it, explaining their approach and reasoning throughout. The focus is on fundamental data structures and algorithms.
**Interviewers look for:** Solid understanding of data structures and algorithms.; Ability to translate a problem into code.; Logical thinking and problem-solving skills.; Clear communication of thought process.
**Evaluation criteria:** Correctness of the code.; Efficiency of the solution (time and space complexity).; Clarity and readability of the code.; Ability to explain the approach and trade-offs.
**Common rejection reasons:** Inability to solve basic coding problems.; Poor understanding of fundamental data structures.; Lack of clear communication during problem-solving.; Not being able to explain the time/space complexity of their solution.
## Questions
