Google Software Engineer interview questions

Interview Process: The process took about 6 weeks from initial recruiter contact to final offer. It was very structured, with clear expectations set up front. The stages were: Recruiter Screen (30 min) Overview of the role, team fit, and my background. Clarified expectations for system design, architecture, and Android platform expertise. Technical Phone Screen (1 hour) One live coding problem focused on algorithmic problem-solving (LeetCode medium-level). Followed by a short discussion on Android framework internals (e.g., how Looper/Handler works, memory management, lifecycle pitfalls). Onsite (virtual in my case) — 5 rounds: Android System Design: Design a large-scale, offline-capable mobile app with sync and caching. Deep dive into architecture decisions, threading models, and performance optimization. General System Design: Not Android-specific — more about designing a distributed system with scalability and reliability in mind. Coding Round 1: Data structures and algorithms (graph traversal + optimization). Coding Round 2: A mix of algorithmic and Android-specific challenges (e.g., implement an efficient image loader with caching). Leadership & Cross-Functional Collaboration: Behavioral interview based on Google’s leadership principles, examples of leading projects across multiple teams, and resolving conflicts.
