apply online and then got an interview opportunity with the hackerrank test, after thet an hr call and then two rounds of tech interviews, after that there is a beharviour interview
I applied online. I interviewed at Booking.com in Nov 2017
Interview
First, four problems to solve on hackerrank. After passing that part i was contacted and interviewed by technology recruiter (common questions about my background and skills). After that, phone screen interview with two tasks, 45 minutes which I did not pass.
Interview questions [1]
Question 1
You have a function f(p) that returns an array of linked pages e.g f(homepage) = {page1, page2, page3}. Or f(page1) = {page4, page5}. If there is no linked pages function will return null. And we say one site is a good site if we can get to any page of that site in a less than 6 clicks. The task was to write a function that will check is it a good site or not using f(p).
I applied through a staffing agency. I interviewed at Booking.com (Amsterdam) in Jun 2026
Interview
Two stages:
- Technical: consisted of two parts. The first one was a hands-on coding exercise where I had to solve a problem, and the second one was focused on system design.
- Culture fit

They asked about idempotency, retry mechanisms, inter-process communication, observability, reliability, and scalability.
I applied through a recruiter. I interviewed at Booking.com
Interview
I recently interviewed with Booking.com for a software engineer role. The process was well-organized and took about 3–4 weeks. It started with an online assessment on HackerRank with a couple of LeetCode medium problems. That was followed by a technical screen where I did live coding and discussed basic algorithms. The final round was a full day of back-to-back sessions: algorithmic coding, system design (something like designing a hotel availability checker), a behavioral round using STAR questions, and a chat with a manager about company values. The interviewers were professional and friendly, and the problems felt relevant to Booking's actual business. On the downside, some coding rounds felt repetitive, and I didn't get much feedback after being rejected. Overall, it was a fair but challenging process. My advice: practice medium-level array and hash map problems, review basic system design, and have solid STAR stories ready. I'd rate it 4 out of 5 stars and would recommend it to other engineers.

Question 1
Design a hotel search and availability system that returns available rooms for a given date range and can handle high traffic.
