## Round 1: Technical Coding Round 1
**Type:** Data Structures and Algorithms Interview · **Difficulty:** Medium · **Duration:** 45 min
Coding challenge focused on data structures and algorithms.
This round focuses on assessing your fundamental programming skills. You will be asked to solve coding problems that typically involve data structures and algorithms. The interviewer will evaluate your approach, the efficiency of your solution, and the quality of your code. Be prepared to explain your thought process and discuss alternative solutions.
**Interviewers look for:** Strong grasp of data structures and algorithms.; Ability to translate a problem into code.; Logical thinking and problem-solving skills.; Attention to detail.
**Evaluation criteria:** Correctness of the solution; 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 articulate thought process clearly.; Poor understanding of fundamental data structures and algorithms.; Code with significant bugs or inefficiencies.; Failure to consider edge cases.
## Questions
