## Round 1: Technical Coding Round 1
**Type:** Data Structures and Algorithms Interview · **Difficulty:** Hard · **Duration:** 60 min
Assess core CS fundamentals through coding problems.
This round focuses on your core computer science knowledge. You will be asked to solve coding problems that test your understanding of data structures (e.g., arrays, linked lists, trees, graphs, hash maps) and algorithms (e.g., sorting, searching, dynamic programming, graph traversal). The interviewer will assess your ability to analyze the problem, devise an efficient solution, implement it in code, and discuss its time and space complexity. Expect to write code on a whiteboard or a shared online editor.
**Interviewers look for:** Strong grasp of data structures and algorithms.; Ability to write clean, efficient, and bug-free code.; Logical thinking and systematic approach to problem-solving.; Ability to communicate technical ideas effectively.
**Evaluation criteria:** Correctness of the solution.; Efficiency of the algorithm (time and space complexity).; Code quality and readability.; Problem-solving approach and ability to break down complex problems.
**Common rejection reasons:** Inability to articulate thought process clearly.; Lack of fundamental data structure or algorithm knowledge.; Suboptimal time or space complexity in code.; Failure to consider edge cases.
## Questions

- Given a binary tree, find its maximum depth.
- Implement a function to reverse a linked list.
