What Is the Interview Process Like for a Software Engineer Role at Airbnb?
The Airbnb software engineer interview process typically spans four to five stages, each designed to rigorously assess your technical skills, problem-solving ability, and cultural fit. You’ll move through these stages like:
- Application Submission
- Recruiter Screen
- Online Coding Assessment
- Virtual On-Site “Engineering Loop”
- Feedback & Hiring Committee
Application Submission
Your journey begins with a detailed online application where your resume, portfolio, and relevant project experience are meticulously reviewed by Airbnb’s recruiting team. This stage is highly competitive, with thousands of applicants vying for a handful of roles, so tailoring your resume to highlight impact, technical depth, and alignment with Airbnb’s mission is essential. Data shows that resumes emphasizing projects with measurable outcomes and technologies relevant to Airbnb’s stack (Ruby, Kotlin, TypeScript) are more likely to be shortlisted. Applicant tracking systems are used, so formatting and keyword optimization can further boost your chances.
Recruiter Screen
If your application stands out, you’ll be invited to a recruiter screen—typically a 15–20 minute informal conversation. Here, recruiters probe your technical background, years of experience, and motivation for joining Airbnb. Expect questions about your familiarity with Airbnb’s tech stack, past projects, and your expectations from the role. This is also an opportunity for recruiters to assess your communication skills and cultural alignment, as Airbnb places a strong emphasis on its “Be a Host” value and collaborative ethos. Confidence and clarity in this round can significantly increase your odds of progressing.
Online Coding Assessment
Next, you’ll tackle the online technical assessment, a critical filter in the process. This round typically features 2–3 algorithmic questions to be solved in 90–120 minutes, often hosted on platforms like HackerRank. The Airbnb coding interview questions focus on core data structures (arrays, trees, graphs), algorithms (DFS, BFS, dynamic programming), and sometimes real-world scenarios or API design. The difficulty is generally medium to hard, with a strong emphasis on writing correct, efficient code that passes all test cases—no pseudocode allowed. Airbnb’s data shows that only about 20–25% of candidates clear this stage, so thorough practice on LeetCode and similar platforms is highly recommended.
Virtual On-Site “Engineering Loop”
The final and most comprehensive stage is the virtual onsite, known as the “Engineering Loop.” This loop consists of four rounds: Coding, Airbnb system design interview, Code Review, and Behavioral. The system design interview often asks you to architect scalable platforms such as a property booking or recommendation system, focusing on high availability, data consistency, and user-centric design. Coding rounds continue to test algorithmic depth, while the code review evaluates your ability to critique and improve real code, mirroring daily engineering work. The behavioral round dives deep into your past experiences, leadership, and how you embody Airbnb’s values, with questions like “Tell me about a time you had to overcome a difficult challenge” or “What does ‘belong anywhere’ mean to you?”. Each session lasts 45–60 minutes, and interviewers are looking for both technical excellence and strong communication.
Feedback & Hiring Committee
After your onsite, Airbnb’s interviewers convene for a 24-hour debrief to calibrate feedback and determine your level (typically E4–E6) and compensation package. The hiring committee, composed of senior engineers and cross-functional leaders, reviews your performance holistically, ensuring fairness and consistency. Airbnb aims to provide feedback within a week, though timelines can vary. A strong performance across all rounds, especially in system design and behavioral interviews, is crucial for a successful outcome. This stage underscores Airbnb’s commitment to a rigorous, transparent, and candidate-focused hiring process.
What Questions Are Asked in an Airbnb Software Engineer Interview?
If you’re preparing for the Airbnb software engineer interview, expect a mix of algorithm, system design, and code-quality questions that reflect real product and infrastructure challenges faced by Airbnb engineers.
Coding / Algorithm Questions
The Airbnb technical interview questions in this section cover core algorithms and data structures, drawn directly from product-inspired scenarios you may face during the Airbnb software engineer interview questions round:
To solve this, calculate the total sum of the list and iterate through the elements while maintaining a running sum of the left side. For each index, compute the right side sum by subtracting the left sum and the current element from the total sum. If the left and right sums match, return the index; otherwise, return -1 after the loop.
To solve this problem, use the XOR operation. XOR all elements in the full list and the missing list. The elements present in both lists will cancel out, leaving only the missing element as the result. This approach works efficiently in (O(n)) time and (O(1)) space.
3. Write a function to return the optimal friend that should host the party
To solve this, calculate the total travel distance for each friend if they were the host by summing up the distances from that friend to all others. The brute-force method has (O(N^2)) complexity. To optimize, calculate the centroid of all friends’ locations and find the friend closest to this centroid, reducing the complexity to (O(N)).
4. Implementing the Fibonacci Sequence in Three Different Methods
To solve this, implement the Fibonacci sequence using three methods: recursive, iterative, and memoization. The recursive method calls itself repeatedly, the iterative method uses loops, and memoization stores computed values to avoid redundant calculations. Recursive has (O(2^n)) time complexity, while iterative and memoization methods are (O(n)).
5. Decreasing Subsequent Values
To solve this problem, iterate through the array and filter out values that are less than any subsequent value. Use a dictionary to track indices and sort values in descending order to identify the largest values at valid indices. Construct the output array by appending values that meet the criteria.
System Design Questions
These Airbnb system design interview questions test your ability to architect scalable, resilient systems that mirror the technical challenges behind Airbnb’s marketplace and user experience at scale:
6. Design a data warehouse for a new online retailer
To design a data warehouse for a new online retailer, start by identifying the business process, such as sales data for analytics. Define granularity to represent each sale as a distinct event, identify dimensions like buyer information (WHO), item details (WHAT), date (WHEN), and payment methods (HOW). Specify facts such as quantity sold, total paid, and net revenue, and then create a star schema to structure the data warehouse efficiently.
7. Create a schema to keep track of customer address changes
To track customer address changes, design a schema with three tables: Customers, Addresses, and CustomerAddressHistory. The CustomerAddressHistory table records each customer’s address history with move_in_date and move_out_date fields, enabling queries for both current and historical addresses. Use normalization and Slowly Changing Dimension Type II practices to ensure data reliability and historical accuracy.
8. Design a database schema for a ride-sharing app
To design a database for a ride-sharing app, consider two use cases: app backend and analytics. For the backend, prioritize query speed with immutable tables using RiderID and DriverID as primary keys, and opt for a NoSQL database for flexibility. For analytics, use a star schema with dimension tables (e.g., users, riders, vehicles) and a fact table with constants like Payment and Trip, ensuring regionalization to optimize costs and query speeds.
To design a system capable of processing and displaying real-time data across multiple platforms, you could use a distributed architecture with a central data processing hub. This hub would handle incoming comments and reactions, ensuring they are persistent and synchronized across platforms. Real-time updates can be achieved using technologies like WebSockets or server-sent events. For AI censorship, dynamic NLP-based filtering might be recommended to handle nuanced content, though static text matching can be faster for simple cases.
10. Given a web app, how would you create a schema to represent client click data?
To represent client click data, design a schema with fields such as action_name, user_id, created_at, session_id, user_agent, value_type, value_id, device, url, and utm. These fields allow tracking of specific actions, user details, session grouping, device type, and associated URLs for analytics purposes.
Code-Review & Quality Questions
This section highlights collaborative engineering questions like code review, testing, and quality practices:
11. How would you design an ML system to predict the movie score based on the review text?
To design an ML system for predicting movie scores based on review text, you can preprocess the text data using techniques like tokenization and embedding (e.g., Word2Vec or BERT). Then, train a regression model (e.g., linear regression, neural networks) on the processed text features to predict scores ranging from 1 to 10.
To design an ML system for extracting and transforming data from the Reddit and Bloomberg APIs, start by building a data ingestion pipeline to fetch data periodically. Use preprocessing steps to clean, normalize, and structure the data for downstream tasks, such as removing noise from Reddit comments or aggregating stock prices. Store the transformed data in a centralized database or data lake, ensuring compatibility with downstream models. Implement monitoring and logging for data quality and pipeline performance, and ensure compliance with data security and privacy standards.
13. How would you review a pull request for a dynamic star-rating widget form?
When reviewing a pull request for a widget like this, check whether the rating component is stateless or stateful and if the design follows accessibility standards (such as using ARIA labels). Ensure that hover interactions, mobile responsiveness, and keyboard navigation are covered by tests. Validate that form submission sanitizes input and handles edge cases like zero or invalid ratings. This is a common Airbnb software engineer interview question star rating widget form topic that blends front-end logic with user experience.
14. How do you evaluate whether a test suite provides sufficient coverage without slowing development?
Start by identifying critical paths and business logic. High coverage is desirable in core modules like payments, bookings, and reviews, where bugs are expensive. Use coverage reports and mutation testing to identify gaps. However, balance the test depth with the need for fast iteration by reserving exhaustive integration tests for production-facing features while maintaining lightweight unit tests for internal logic. Periodically prune slow or flaky tests.
Senior / Staff Track Questions
If you’re preparing for an Airbnb staff engineer interview or navigating the Airbnb senior software engineer interview, these questions assess your technical leadership and architectural judgment on complex, ambiguous problems:
To design the system, divide it into three sections: the data source, processing engine, and dashboard. Use a centralized backend or direct POS integration for real-time data acquisition, implement a processing engine with in-memory storage for updates, and design the dashboard to query sales rankings every few seconds. Ensure reliability through redundancy and load balancing.
16. Find out the number of users that gave a like on a certain date
To count the number of users who gave a like on June 6, 2020, filter the events table for rows where the created_at date matches “2020-06-06” and the action is “like”. Use the COUNT() function with the DISTINCT keyword to count unique user_ids.
Mobile & Frontend Variants
Airbnb’s mobile and frontend interviews evaluate real-world decisions, such as rendering strategy, accessibility, and app performance—whether you’re entering an Airbnb frontend interview, Airbnb Android interview, or Airbnb iOS interview:
17. How would you decide between Server-Side Rendering (SSR) and Client-Side Rendering (CSR) for Airbnb’s listing search page?
To make this decision, consider the trade-offs. SSR provides faster initial load and is better for SEO, which benefits public-facing pages like search or listing previews. However, CSR offers smoother client-side transitions and can reduce server load during peak traffic. A hybrid approach using frameworks like Next.js may offer the best of both worlds, rendering the first view on the server and deferring the rest to the client. This is a commonly discussed problem in an Airbnb frontend interview.
18. How would you structure the ViewModel for a booking confirmation screen in an Android app?
Begin by defining the screen’s UI state, such as guest details, pricing summary, and network status. Use a LiveData or StateFlow inside a ViewModel to hold this state. Separate business logic from UI logic and inject dependencies using a DI framework like Hilt. Handle lifecycle events explicitly and prevent memory leaks by cleaning up observers. This is a typical discussion topic in an Airbnb Android interview, where architectural clarity and modularization are key.
19. How would you improve perceived performance when loading a photo gallery in a mobile app?
Improve perceived performance using placeholder skeleton screens and lazy loading. Pre-fetch images before the user scrolls to them, and cache images using Glide on Android or NSCache on iOS. Compress images on the backend and consider progressive image loading (e.g., blur-up effect). Also, reduce layout overdraw and avoid unnecessary re-renders. These techniques are often explored in Airbnb mobile interviews, where UI responsiveness directly impacts booking behavior.
20. What accessibility checks would you include in a mobile UI review?
Check for proper use of semantic labels, contrast ratios, and support for screen readers. For iOS, verify that accessibilityLabel, accessibilityTraits, and VoiceOver navigation works as expected. For Android, ensure contentDescription, focus order, and TalkBack support are complete. Accessibility is not just a checkbox — it affects booking inclusivity and legal compliance, making it a frequent follow-up in both Airbnb iOS interview and Airbnb android interview sessions.
