Throughout this process, Rent The Runway aims to match you with a specific team or product area, meaning a portion of your final rounds will focus heavily on the functional domain of that team.

The visual timeline above outlines the standard progression of stages you will navigate during the hiring process. Candidates should use this timeline to pace their preparation, ensuring they focus on core coding skills early on before transitioning to system design and behavioral stories for the final loop. While the sequence remains relatively consistent, the exact focus of the technical rounds may vary depending on whether you are aligned with frontend, backend, or platform engineering teams.

To succeed at Rent The Runway, you must perform consistently well across several distinct evaluation areas. Understanding what your interviewers are looking for in each of these areas will help you structure your preparation effectively.

Coding and Problem Solving

This area evaluates your ability to translate abstract requirements into clean, working code. The interviewers want to see how you approach a problem, break it down, and write structured code to solve it.

Be ready to go over:

• Data structures – Deep understanding of arrays, hash maps, trees, graphs, queues, and stacks.
• Algorithm design – Proficiency with sorting, searching, recursion, and dynamic programming.
• Code quality – Writing readable, maintainable, and idiomatic code with proper variable naming and modular structure.
• Advanced concepts (less common) – Multi-threading, concurrency control, and memory-efficient stream processing.

Example scenarios:

• Implementing a search auto-complete system for a designer catalog.
• Parsing and validating complex JSON payloads representing inventory transactions.
• Optimizing a route-finding algorithm for warehouse picking paths.

System Design and Architecture

System design rounds assess your ability to design high-scale, distributed systems. You will need to balance technical tradeoffs and design architectures that are resilient, scalable, and cost-effective.

Be ready to go over:

• Microservices design – Designing decoupled, domain-driven services that communicate via REST APIs or event streams.
• Data storage strategies – Choosing between relational databases (SQL) and non-relational databases (NoSQL) based on write/read patterns.
• Caching and performance – Implementing caching layers (e.g., Redis, Memcached) to reduce database load and improve response times.
• Advanced concepts (less common) – Event sourcing, CQRS (Command Query Responsibility Segregation), and designing for eventual consistency in distributed transactions.

Example scenarios:

• Designing the backend architecture for a flash sale event with massive concurrent traffic.
• Designing a distributed lock manager to prevent concurrent bookings of a single physical item.
• Architecting an analytics pipeline to track garment usage and wear-and-tear metrics over time.

Functional Fit and Domain Expertise

Because Rent The Runway aligns candidates with specific teams prior to the onsite loop, this round focuses heavily on your domain-specific expertise and your ability to solve problems unique to that team's scope.

Be ready to go over:

• Frontend/Backend specialization – Deep understanding of your primary tech stack (e.g., React/JavaScript for frontend, Java/Python/Go for backend).
• Integration patterns – Designing clean APIs and integrating with third-party logistics or payment providers.
• Testing and quality – Writing comprehensive unit, integration, and end-to-end tests to ensure system stability.

Example scenarios:

• Building a responsive, accessible UI component for a complex subscription checkout flow.
• Designing a robust error-handling and retry mechanism for a third-party shipping API integration.
• Optimizing database queries and indexes to handle millions of active subscription records.
