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 through a recruiter. I interviewed at Booking.com
Interview
The interview process is simple and same as described by other people. I'd like to add a couple of things to this -
- Recruiter was very polite and helpful in my case.
- Strong emphasis on justifying your algo/system design choices with numbers/experience/rational reason.
- Interviewers do give hints if you're not going in the right direction but if you fail to catch them and correct your solution, that shows rigid mentality and it's a big negative sign.
- Bonus points for being proactive in finding edge cases and bugs in your code/design and correcting them.
- In no interview did I feel like I was being interviewed. They all felt like discussions between colleagues.
Interview questions [2]
Question 1
Straightforward algorithm question followed with discussions on scaling and how to productionize it
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

Question 1
They asked about idempotency, retry mechanisms, inter-process communication, observability, reliability, and scalability.

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.
