## Round 1: Technical Screening
**Type:** Technical Screening (Coding) · **Difficulty:** Medium · **Duration:** 45 min
Assess fundamental coding skills and problem-solving with data structures and algorithms.
This initial round focuses on assessing fundamental programming skills and problem-solving abilities. Candidates will be asked to solve coding problems, typically involving data structures and algorithms, on a shared coding platform. The interviewer will evaluate the candidate's approach, code quality, and understanding of time and space complexity.
**Interviewers look for:** Ability to translate a problem into code.; Understanding of basic data structures and algorithms.; Logical thinking and systematic approach to problem-solving.; Clear communication of thought process.
**Evaluation criteria:** Correctness of the solution; Efficiency of the solution (time and space complexity); Code readability and maintainability; Problem-solving approach
**Common rejection reasons:** Inability to solve basic coding problems.; Poor understanding of fundamental data structures.; Lack of clarity in thought process.; Inability to explain code logic.
## Questions

- Given an array of integers, return indices of the two numbers such that they add up to a specific target.
- Implement a function to check if a binary tree is a Binary Search Tree (BST).
- Find the middle element of a linked list.

## Preparation tips

- Practice coding problems on platforms like LeetCode, HackerRank.
- Focus on common data structures (arrays, linked lists, trees, hash maps) and algorithms (sorting, searching, recursion).
- Be prepared to explain your thought process clearly.
- Write clean, well-commented code.

## Round 2: System Design Round
**Type:** System Design · **Difficulty:** Medium · **Duration:** 60 min
Assess understanding of system design principles and ability to design scalable systems.
This round focuses on system design and architecture. Candidates will be presented with a high-level problem and asked to design a system to solve it. This involves discussing components, data flow, scalability, reliability, and trade-offs. For an SDE 1 role, the focus will be on understanding fundamental concepts rather than deep architectural expertise.
**Interviewers look for:** Ability to break down complex problems.; Knowledge of common system design patterns.; Understanding of scalability, availability, and performance.; Ability to articulate design choices and trade-offs.
**Evaluation criteria:** Understanding of system design principles.; Ability to design scalable and reliable systems.; Trade-off analysis and justification.; Consideration of various system components (databases, caching, load balancing).
**Common rejection reasons:** Inability to design scalable solutions.; Lack of understanding of distributed systems concepts.; Poor trade-off analysis.; Not considering edge cases or failure scenarios.
## Questions

- Design a URL shortening service like bit.ly.
- How would you design a system to count the number of views for a video?
- Design a basic rate limiter.

## Preparation tips

- Study common system design patterns (e.g., load balancing, caching, database sharding).
- Understand concepts like scalability, availability, consistency, and latency.
- Practice designing common systems like URL shorteners, social media feeds, or chat applications.
- Be prepared to discuss trade-offs between different design choices.

## Round 3: Managerial Round
**Type:** Behavioral and Managerial Interview · **Difficulty:** Medium · **Duration:** 45 min
Assess behavioral competencies, past experiences, and cultural fit with the team and company.
