## Round 1: Coding Challenge
**Type:** Technical Coding Interview · **Difficulty:** Medium · **Duration:** 45 min
Assess coding proficiency with data structures and algorithms.
This round focuses on your fundamental programming skills. You will be given one or two coding problems to solve in a shared editor. The interviewer will assess your ability to understand the problem, devise an efficient solution, write clean and correct code, and explain your thought process. Expect questions on data structures, algorithms, and basic problem-solving.
**Interviewers look for:** Clear thinking; Ability to translate requirements into code; Attention to detail; Proficiency in at least one programming language
**Evaluation criteria:** Correctness of solution; Efficiency of solution (time and space complexity); Code readability and maintainability; Problem-solving approach
**Common rejection reasons:** Inability to articulate thought process.; Poorly structured or inefficient code.; Lack of understanding of fundamental algorithms.; Inability to debug effectively.
## Questions
