1. Phone Screen

Duration: 45 minutes Details: The phone screen was conducted by a Google software engineer. It involved a technical interview focused on data structures and algorithms. I was asked to solve two coding problems on a shared online editor. The interviewer was friendly and provided hints when necessary. Key topics included binary trees and dynamic programming.

1. Technical Phone Interview

Duration: 1 hour Details: This was a more in-depth technical interview. The interviewer presented a complex problem involving system design and coding. The problem required a good understanding of distributed systems and optimization techniques. I had to explain my thought process and write code to solve the problem. The interviewer also asked questions to probe my understanding of scalability and performance considerations.

1. Onsite Interview

Duration: Full day Details: The onsite interview consisted of five rounds, each lasting about 45 minutes. The rounds were a mix of coding, system design, and behavioral questions.

• Coding Rounds (3): Focused on algorithmic problems and data structures. Problems ranged from medium to hard difficulty. Topics included graph algorithms, dynamic programming, and design patterns. I had to write clean, efficient code and explain my approach clearly.
• System Design Round (1): Required designing a scalable system. I had to discuss the architecture, technologies to use, and how to handle potential bottlenecks.
• Behavioral Round (1): Focused on past experiences, teamwork, and problem-solving skills. Questions revolved around handling conflicts, working in a team, and dealing with challenging projects.
