I still think about the day Airbnb rejected me more than I should.
It was late in the afternoon when I walked out of my final round and ended up sitting in my car for twenty minutes, staring at the steering wheel. The rejection, once the recruiter spelled it out for me, came down to a belonging question, not coding, not system design, a question about making someone feel welcome on a team.
Back then, fresh off a string of Google interviews, I was treating coding prep as the whole game. I had twelve STAR stories written out and rehearsed, every single one of them about shipping features or handling disagreements or technical stuff. With all of that sitting in my head ready to recite, the story bank was the part of my prep I worried about least, and also the part I had finished first and never reopened.
The amount of attention I gave their culture round was directly proportional to that. Mock coding sessions were getting scheduled all the time. Graph problems before work and system design videos at lunch were the norm.
All that grinding caused me to be a bit single minded about the technical rounds. A former teammate was even making fun of me because of it, she kept telling me, six months out, that culture carries the same weight as coding in their final debrief. I laughed at her, out loud, and she didn't argue, she just changed the subject. I thought I was doing everything right.

I got three questions in that room, and all three were about making people feel like they belong. Not one of my twelve stories was about inclusion. The best I could dig up was a story about onboarding a new engineer at my last company, and while I was saying it out loud I knew it sounded like garbage. "Be a Host" and "Belonging" are their actual core values, not poster slogans, and I had nothing that touched either one.
Mediocre coders who nail culture get offers, strong coders who blow culture get rejected, that was the math my teammate had spelled out for me. I had filed all of that under her being a bit dramatic about her old employer. She had been describing the actual scoring.
The funnel itself went like this for me. Before you talk to any human there was a HackerRank test, two problems, medium difficulty, forty five minutes.
I got array manipulation and a binary tree problem. Someone in a coding bootcamp Discord I lurk in got a graph instead of the tree, so they rotate through a bank of questions.
They also wanted real running code, not pseudocode, and that threw me, because I was coming from Google interviews where everything stayed on a whiteboard.
From there, a thirty minute recruiter call, that one was basically a check that I was a normal human who actually wanted the job.
The phone screen was forty five minutes. I got DFS connected components, knocked it out in about twenty, and my interviewer spent the rest of the time helping me look for edge cases, at one point she literally said "you might want to check empty input".
I nearly fell out of my chair. Nobody hands you anything at Google, or at least nobody ever handed me anything there.
At Airbnb they nudged me along the whole way. They drew on the whiteboard with me, and during system design my interviewer was standing next to me at the board sketching alongside me, the whole thing had a pair programming energy to it. The coding was a completely different experience from Google, mostly because the interviewers actually talked to me.
The final round day itself was two coding rounds and the system design. The first coding round was binary tree path sums with a depth constraint, which was manageable, and I remember actually feeling good at that point.
The second was interval merging on overlapping reservation windows, framed around guest bookings that conflict with each other, and it felt like something pulled straight out of their production code. It ran medium to hard, I came close on the time but finished, and I spent the last ten of those forty five minutes sweating.
My teammate explained afterwards that they always do this, every problem comes dressed in Airbnb language, bookings and listings and availability windows and reservations. Underneath you find the same trees and arrays and graphs and intervals you have been grinding all along, nothing exotic anywhere, not in any round of mine anyway.
The system design prompt was "build a booking and listing system", and my interviewer kept lobbing scenarios at me. What happens when two guests book the same listing at the exact same second, that was the first one. Then she hit me with a host going silent in the middle of a booking. The pricing scenarios came after that, pricing that changes depending on the week and the season, and somewhere past that point I lost count, she just kept going.
I had done the standard YouTube hotel booking prep. It got me through maybe forty percent of what she threw at me, the rest was all Airbnb domain stuff, and I sat there straight up inventing answers.

Try InterviewMan FreeGeneric "design Twitter" prep falls apart in that room, and I can tell you exactly where it falls apart too: double-booking concurrency and how to handle it, host and guest state machines, dynamic pricing, how their search ranking works, availability calendars at scale. Nobody on YouTube was covering any of that in the videos I had been watching.
The second time around I did that round differently. Restate the goal in my own words, ask questions to narrow scope, throw out reasonable numbers myself, start really high level, then drill into whatever she seemed most interested in. Double-booking was the thing she pushed hardest on, both times. And on the second pass, system design turned into my favorite part of the whole day, which is wild, considering it is the round I bombed the first time, and I mean really bombed.
Even the lunch is only "not scored" in air quotes. A thread on r/cscareerquestions had someone whose lunch buddy mentioned something about them during the debrief. So be normal through the whole day.
Months later I came back for attempt two, and this time I ran InterviewMan through the whole thing. The difference between the two attempts is what sold me on building for this problem full time.
The culture round started and it had already pulled up a belonging story from a conversation I had with it earlier, before I had even registered what the interviewer was fishing for. My entire rejection had been over belonging. In coding it had the DFS approach up within seconds of the problem appearing. In system design it flagged double-booking concurrency right away, the same angle my interviewer had pushed hardest on the last time.
We tested dock visibility, the process list, Activity Monitor, across HackerRank and Zoom, and nothing showed. Twelve bucks a month on annual, fifty seven thousand people use it, more than twenty stealth features, no session caps. Interview Coder wants two ninety nine a month and only does coding, and coding is two of five rounds here, the two that matter least at Airbnb.
My old teammate was right about literally everything. Culture stories are what decide your outcome at this company, real ones, with names and moments you actually lived through.
I remember telling her about the rejection. She did not say anything for about five seconds, which I took as "I literally warned you", and she would have been entitled to say it out loud.
After that I mostly stopped retelling the story, I did not want to walk back through it, I did not really care to. I was just furious with myself for showing up with twelve polished stories and zero about belonging when she had told me exactly which round mattered. I learned it the expensive way.
