## Round 1: Data Structures and Algorithms Round
**Type:** Technical Interview (Coding) · **Difficulty:** Medium · **Duration:** 45 min
Coding problem focused on data structures and algorithms.
This round focuses on assessing your core programming skills. You will be asked to solve one or two coding problems, typically involving data structures and algorithms. The interviewer will evaluate your ability to write clean, efficient, and correct code, as well as your approach to problem-solving and debugging.
**Interviewers look for:** Clean, efficient, and bug-free code.; Logical and structured approach to problem-solving.; Ability to explain trade-offs of different solutions.
**Evaluation criteria:** Correctness of the solution.; Efficiency of the solution (time and space complexity).; Code clarity and maintainability.; Problem-solving approach.
**Common rejection reasons:** Inability to articulate thought process.; Poor coding practices or syntax errors.; Fundamental misunderstanding of data structures/algorithms.
## Questions

- Implement a function to reverse a linked list.
- Find the kth smallest element in a binary search tree.

## Preparation tips

- Practice coding on a whiteboard or a simple text editor.
- Think out loud and explain your approach before coding.
- Test your code with edge cases.

## Round 2: System Design and Architecture Round
**Type:** System Design Interview · **Difficulty:** Hard · **Duration:** 60 min
Design a scalable system and discuss architectural choices.
This round evaluates your ability to design and architect complex systems. You will be given an open-ended problem, such as designing a specific service or application, and you'll need to discuss the architecture, data models, APIs, scalability considerations, and potential trade-offs. This is a crucial round for MTS IV level roles.
**Interviewers look for:** A structured approach to system design.; Ability to identify bottlenecks and propose solutions.; Deep understanding of distributed systems principles.; Pragmatic decision-making.
**Evaluation criteria:** Scalability of the proposed design.; Reliability and fault tolerance.; Understanding of trade-offs (e.g., consistency vs. availability).; Knowledge of relevant technologies (databases, caching, messaging queues).
**Common rejection reasons:** Lack of understanding of distributed systems concepts.; Inability to design scalable and reliable systems.; Poor trade-off analysis.
## Questions

- Design a system like Google Maps.
- How would you design a rate limiter for an API?

## Preparation tips
