Airbnb Staff Software Engineer Interview Questions

1.Walk me through a recent project where your team was distributed across multiple time zones. How did you ensure effective collaboration and what specific challenges did you hit?

2.Give me an example of when you identified that a system or process was creating barriers for certain users and took action to fix it. What did you change?

3.Tell me about a time you pushed for a user experience improvement that required significantly more engineering effort than your team initially wanted to invest. What was the UX issue and how did you make the case?

4.Describe a time when you had to convince your leadership to invest engineering resources in improving user experience rather than building new features. What was your approach?

5.Describe a specific feature or system you built that needed to work well for users with very different backgrounds, locations, or accessibility needs. What inclusion challenges did you encounter?

6.Tell me about a product decision where you had to balance what hosts wanted versus what guests needed. What was the tension and how did you resolve it?

7.Write code to detect potentially fraudulent booking patterns in our transaction stream. Focus on identifying coordinated attacks where multiple fake accounts book the same property.

8.Implement a function that calculates dynamic pricing recommendations for hosts based on local demand, seasonality, and property features. Keep it simple but extensible.

9.We have a Ruby service that processes booking confirmations, and during Black Friday last year it started timing out when traffic spiked 10x. Walk me through how you'd approach scaling this to handle millions of bookings per day.

10.You need to implement a feature flag system that can handle millions of requests per second across our microservices. What's your approach?

11.Design the core matching algorithm that decides which listings to show a guest when they search for accommodations in Paris. Consider we have 100,000+ active listings there.

12.Our host messaging service built in Java needs to support real-time notifications across mobile apps, web, and email. How would you architect this to handle millions of active hosts?

13.Walk me through how you built technical credibility with a new team that was skeptical of your leadership.

14.Describe a time when you identified that your team's technical approach was creating a poor experience for hosts or guests, even though it met all the engineering requirements.

15.Describe a time when you inherited a critical system that was poorly documented and the original engineers had left the company. How did you get your team up to speed?

16.Tell me about a time you had to coordinate a major technical initiative across teams that each had competing quarterly goals.

17.Tell me about a time you had to influence a VP or director to change their technical roadmap priorities. What was your approach and what happened?

18.Give me an example of when you had to make a controversial technical decision that affected multiple product teams. How did you handle the pushback?

19.Airbnb's search result pages load in about 200ms globally. If we added a new feature that increased this to 400ms, estimate the business impact in lost bookings per year.

20.Imagine our payment processing fails for 30 minutes during peak European booking hours. Walk me through estimating the immediate revenue loss and the longer-term impact on host and guest trust.

21.Our Trust & Safety team reports that 3% of new host signups are potentially fraudulent accounts. Walk me through how you'd estimate the cost to Airbnb if we reduced our fraud detection threshold to catch 95% instead of 85% of these accounts.

22.A new competitor launches with 50% lower fees than Airbnb. Our host acquisition in major cities drops 30% month-over-month. Walk me through how you'd assess whether this is due to the competitor or other factors.

23.We're seeing 15% of guest searches return zero results in certain rural areas. Estimate how much revenue Airbnb loses annually from this problem and what the ROI would be for a dedicated team to fix it.

24.Estimate how many customer service tickets Airbnb receives daily and what percentage could be eliminated by better product design. Walk me through your reasoning and where you'd focus first.
