Airbnb Software Engineer Interview Questions

1.Describe a feature or system you built that needed to work well for users from very different backgrounds or regions. What specific considerations did you account for?

2.Tell me about a system or feature you designed that needed to serve users with very different technical constraints or capabilities. What approach did you take?

3.Tell me about a time you pushed for a design or UX improvement that required significant additional engineering work. How did you make the case and what was the outcome?

4.Walk me through a challenging project where your team was distributed across multiple time zones. How did you ensure effective collaboration and delivery?

5.Tell me about a time you had to make a technical decision that affected both sides of a marketplace or platform. How did you balance the competing needs?

6.Describe a time when you advocated for refactoring or technical improvements that would primarily benefit user experience rather than add new features. How did you get buy-in?

7.You're working on the host pricing recommendations feature and notice that hosts in rural areas are getting poor suggestions while urban hosts get great ones. Walk me through how you'd debug this and what solutions you might propose.

8.Walk me through how you'd implement a feature flag system that can safely roll out new booking flow changes to 1% of users initially, then gradually increase to 100% based on conversion metrics.

9.Our search ranking algorithm needs to balance showing guests the most relevant listings while ensuring all hosts get fair exposure. How would you approach this two-sided marketplace problem?

10.You need to build a real-time notification system that alerts guests when their host sends them a message. The system needs to handle 50M+ daily messages across web, mobile, and email. What's your architecture approach?

11.You're tasked with building a trust and safety system to detect potentially fraudulent listing photos. The system needs to process 10K+ new photos daily while maintaining high accuracy to protect guest safety. How would you architect this?

12.Design a caching strategy for Airbnb's search results that can handle peak traffic during major events like Olympics or New Year's while ensuring users see the most up-to-date availability and pricing.

13.Design a system that can dynamically adjust booking cancellation policies based on local events, holidays, and market conditions. The system needs to process policy changes for 7 million listings in real-time while ensuring fairness for both hosts and guests.

14.You need to build a system that automatically detects and prevents duplicate listings across Airbnb's 7 million properties. How would you design this to catch sophisticated attempts while minimizing false positives that could hurt legitimate hosts?

15.Design the backend systems needed to support Airbnb's 'Live and Work Anywhere' employee policy. The system needs to handle expense tracking, tax compliance, and equipment shipping for 6000+ employees working from any country.

16.Build a dynamic pricing system for Airbnb Experiences that can optimize prices in real-time based on demand, weather, local events, and host availability. The system needs to handle 150,000+ experiences across different categories and time zones.

17.Design a real-time translation system that can handle chat messages between hosts and guests who speak different languages. The system processes 50 million messages daily and needs to preserve cultural context and hospitality nuances.

18.You're building a system to coordinate emergency response when natural disasters affect Airbnb properties and guests. The system needs to identify impacted bookings, coordinate with local authorities, and manage guest relocations across potentially thousands of affected listings.

19.Tell me about a time you had to influence a product manager or designer to change their approach when you believed it would create technical debt or scalability issues down the line.

20.Tell me about a time you took ownership of improving developer experience or engineering productivity for your team or a broader group of engineers.

21.Describe a situation where you had to coordinate with multiple teams to solve a problem that was affecting user trust or safety. How did you approach the coordination and what was the outcome?

22.Walk me through a time when you had to make a technical decision that would significantly impact hosts' ability to manage their listings or earnings. How did you approach understanding their needs?

23.Describe a time when you had to lead a technical migration or architectural change that required getting buy-in from senior engineers or tech leads across multiple teams who had different priorities.

24.Tell me about a time you identified that your team was building something that wouldn't actually create belonging or improve the experience for a underserved user group. How did you handle that situation?

25.Estimate how many hosts would need to update their listing photos in a typical month if Airbnb implemented a new photo quality standard. Walk me through your reasoning.

26.If guest support tickets increased 25% but average resolution time stayed flat, what could explain this and how would you investigate?

27.Our host response rate dropped 3% this quarter across all regions. No major product changes shipped. How would you investigate this?

28.You notice booking success rates are 15% higher for guests who view the host profile page versus those who don't. How would you increase profile page visits?

29.Estimate the revenue impact if Airbnb reduced search result load time from 800ms to 400ms across all markets. What assumptions would you make?

30.Estimate how much server capacity Airbnb would need during a major global event like the World Cup if bookings increased 300% in host cities. Walk through your calculations.
