• Advanced concepts (less common) – Local caching strategies, custom transition animations, and writing comprehensive unit tests for your business logic.

Example scenarios:

• Building a mini-music player app that fetches a list of tracks from a mock API, displays them in a list, and simulates audio playback with a progress bar.
• Creating a search interface that handles rapid user input with debouncing and updates the UI smoothly without blocking the main thread.

Live Code-Pairing

If your take-home exercise meets the team's standards, you will participate in a live code-pairing session during the panel interviews. This session focuses on real-time collaboration, debugging, and feature extension.

Be ready to go over:

• Refactoring – Improving the performance or readability of an existing piece of code.
• Feature Extension – Adding a new capability (such as a "favorites" system or offline mode) to your take-home submission or a provided codebase.
• Debugging – Identifying and resolving runtime issues, memory leaks, or UI rendering bugs.

Example scenarios:

• "Let's take the music player you built in your take-home and add a feature that allows users to reorder the playback queue."
• "There is a performance bottleneck when scrolling through this list of high-resolution album artwork. Let's profile the app together and fix the lag."

Mobile Systems Design

The systems design session is highly conversational and tests your ability to architect complex mobile systems from scratch. You will need to think about data flow, networking, storage, and platform constraints.

Be ready to go over:

• Network Layer Design – Designing robust API clients, handling authentication tokens, and managing payload serialization.
• Local Persistence – Selecting and implementing database solutions (e.g., CoreData, Room, SQLite) and handling schema migrations.
• Media Playback Architecture – Designing audio streaming pipelines, managing system audio focus, and handling background execution.
• Advanced concepts (less common) – Implementing real-time communication protocols (WebSockets, gRPC) and designing modular multi-module codebases.

Example scenarios:

• "Design the client-side architecture for a music generation app where users can tweak generation parameters in real-time and stream the resulting audio."
• "How would you design an offline-first experience for a mobile app where users can continue to browse their generated tracks and queue up new creation requests?"

Behavioral & Culture Fit

At Suno, how you work is just as important as what you build. The behavioral sessions use the "explain a time when" format to understand your past experiences, leadership qualities, and how you navigate team dynamics.
