Airbnb·Product Manager·Onsite - Product Sense / Strategy

Apr 2026
Interviewed for a PM role at Airbnb and got asked about WeWork's collapse. Short post, one question, not much else to report.
  • Why did WeWork fail?

“This is a classic case question but it goes deeper than it looks.”

Airbnb·Software Engineer·Onsite - System Design / Architecture

Apr 2026
Airbnb system design round, got asked to design their search feature. Pretty open-ended and I kept second-guessing how deep to go on the backend vs the ranking logic.
  • Design Airbnb's search functionality.

“I jumped straight into the database schema and the interviewer had to nudge me back toward clarifying requirements first.”

Airbnb·Machine Learning Engineer·Onsite - System Design / Architecture

Apr 2026
Airbnb ML system design round focused on building a relisting recommendation system. Pretty deep technically and covered more ground than I expected in one session.
  • Design a system that decides which previously-viewed listings to re-surface to users, covering spatial indexing, a ranking pipeline, evaluation outputs, and how changes to those outputs affect live metrics.

“This was a lot to pack into one question.”

Airbnb·Software Engineer·Onsite - System Design / Architecture

Apr 2026
Airbnb frontend-heavy system design round focused on building a lodging reservation widget from scratch. The scope was bigger than I expected and the edge case discussion at the end really caught me off balance.
  • Design a lodging reservation widget that includes check-in and check-out date inputs, dynamic pricing based on number of adults and children, guest count validation against room capacity, a disabled 'Book Now' button for sold-out or invalid states, and a confirmation dialog on submit. Walk through your component state, data models, and error states.
  • How would you test edge cases like minimum night requirements, partial availability windows, timezone and daylight saving time transitions, and price rounding in this widget?

“I started with state shape and that was probably the right call.”

Airbnb·Software Engineer·Technical Phone Screen

Apr 2026
Airbnb software engineer interview with a graph optimization problem. Pretty niche question that took me a minute to wrap my head around, but once I saw it as a path-scoring problem it clicked.
  • You're given a directed graph with edge costs and per-node rewards. Starting from a fixed start node, traverse edges until you reach any end node. The score is the total node rewards collected minus the total edge costs paid. Find the maximum achievable score.

“Took me a second to not just reach for Dijkstra out of habit.”

Airbnb·Software Engineer·Onsite - System Design / Architecture

Apr 2026
Airbnb system design round, one big question about building an availability notification system for listings. Felt pretty solid on the core pieces but the dedup and fanout details got messy under pressure.
  • Design a system that notifies users when a listing they're watching (vacation rental, hotel, product) becomes available for booking. Users can subscribe with criteria like a date range, and the system needs to detect availability changes, send alerts through the user's preferred channel, and avoid sending duplicate notifications.

“I started with the subscription store and the event source, which felt natural, but I got tripped up when they pushed on the fanout side.”

Airbnb·Software Engineer·Onsite - Behavioral / Leadership

Apr 2026
Airbnb SWE interview with what felt like a culture/values question dressed up as a softball. Short but made me think more than I expected.
  • What does 'belong anywhere' mean to you personally?

“I kind of rambled about inclusivity and travel and then realized halfway through I wasn't actually connecting it back to engineering or my work.”

Airbnb·Product Designer·Onsite - Product Sense / Strategy

Apr 2026
Got a product design question at Airbnb that had nothing to do with travel or hospitality, which threw me off more than I expected. Single question, but it had a lot of layers if you actually dug into it.
  • Design a dashboard for police officers to use when recording crimes.

“My first instinct was to jump straight into UI patterns and I had to stop myself.”

Airbnb·Software Engineer·Onsite - Behavioral / Leadership

Apr 2026
Behavioral round for a software engineer role at Airbnb. The questions leaned hard into Airbnb's culture and values, which makes sense in retrospect but felt a bit unexpected for an engineering interview.
  • Why do you want to join Airbnb?
  • Tell me about a time you hosted others, whether that's an event, a community gathering, or something similar.
  • Walk me through a time you gave difficult feedback to someone, and separately a time you received hard feedback and had to act on it.
  • Share a story that shows how you've built community or brought people together.
  • Who inspires you most and why?
  • Describe the most challenging problem you've worked on: what you did and what the result was.

“Pretty standard opener.”

Airbnb·Machine Learning Engineer·Technical Phone Screen

Apr 2026
Airbnb ML Engineer interview with a coding round that was basically a coin change problem dressed up in airport logistics clothing. The theme was cute but the problem was pretty standard once you stripped the flavor text away.
  • Given a target amount and a list of canister capacities (each usable unlimited times), find the minimum number of canisters that sum to exactly the target. Return -1 if it's impossible.

“Classic unbounded knapsack / coin change in disguise.”
