## Round 1: Data Structures and Algorithms
**Type:** Technical Interview - Coding · **Difficulty:** Medium · **Duration:** 45 min
Solve coding problems focusing on data structures and algorithms.
This round focuses on assessing your core programming skills and problem-solving abilities. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will evaluate your approach, the efficiency of your solution, and your ability to write clean, working code. Expect to explain your thought process throughout the problem-solving exercise.
**Interviewers look for:** A systematic approach to problem-solving.; Proficiency in coding the solution.; Clear communication of the thought process.; Understanding of time and space complexity.; Ability to identify and handle edge cases.
**Evaluation criteria:** Correctness of the solution.; Efficiency of the solution (time and space complexity).; Code clarity and readability.; Ability to explain the approach and trade-offs.; Handling of edge cases and constraints.
**Common rejection reasons:** Inability to articulate thought process.; Poor coding practices (e.g., inefficient solutions, unreadable code).; Lack of understanding of fundamental data structures and algorithms.; Failure to address edge cases in coding problems.
## Questions

- Given an array of integers `nums` and an integer `target`, return indices of the two numbers such that they add up to `target`.
- Implement a function to check if a binary tree is a valid Binary Search Tree (BST).

## Preparation tips

- Practice coding problems on platforms like LeetCode, HackerRank.
- Focus on understanding time and space complexity.
- Be prepared to explain your code line by line.
- Think out loud and communicate your approach clearly.

## Round 2: Core Programming Concepts
**Type:** Technical Interview - Concepts · **Difficulty:** Medium · **Duration:** 45 min
Assess understanding of programming concepts and basic system design.
This round is a more general technical interview that might cover a broader range of topics. It could include questions about object-oriented programming, system design basics (for entry-level, this might be simplified), database concepts, or specific language features. The interviewer will assess your foundational knowledge and how you apply it to solve technical challenges.
**Interviewers look for:** Solid grasp of programming language fundamentals.; Logical approach to coding tasks.; Attention to detail.; Ability to debug and find errors.; Proactive communication.
**Evaluation criteria:** Understanding of core programming concepts.; Ability to write syntactically correct code.; Problem decomposition and logical thinking.; Debugging and error handling.; Ability to ask clarifying questions.
**Common rejection reasons:** Lack of understanding of fundamental programming concepts.; Inability to translate requirements into code.; Poor debugging skills.; Not asking clarifying questions.
## Questions

- Explain the concept of polymorphism with a real-world example.
- What is the difference between `==` and `.equals()` in Java?
- Describe how you would optimize a slow database query.

## Preparation tips

- Review OOP principles.
- Understand basic system design concepts.
- Brush up on common data structures and algorithms.
- Be ready to explain concepts clearly.

## Round 3: Behavioral and Team Fit
**Type:** Behavioral / Managerial Interview · **Difficulty:** Medium · **Duration:** 45 min
Assess behavioral skills, teamwork, and cultural fit.
