Booking’s highest-frequency topics for this role include system design, live coding, behavioral or fit interviews, and optimization, including algorithmic or code optimization. SQL and REST APIs are explicitly called out as fundamentals candidates often overlook, and conflict resolution and professional collaboration are also tested. Example public prompts include optimizing booking log processing and balancing speed and maintainability.

What does the technical assessment at Booking evaluate for a Backend Engineer?

The technical assessment is described as a rigorous evaluation of your backend-relevant technical skills. Based on the role’s topic emphasis, you should expect live coding and problem solving that includes optimization and performance-focused reasoning.

Average Positive Amsterdam

I applied through the portal and the OA showed up the very next day. The assessment gave me 90 minutes, and I had to solve problems that involved REST API and SQL. I hadn’t expected those topics to be part of the coding OA, so I didn’t get to a polished result. I remember leaving feeling like my solutions were only partially correct. The rejection came back the next day, which made the whole thing feel very abrupt.

I had a pretty positive experience with a three-round flow that ultimately led to an offer. After the initial steps, the interviews lined up as system design first, then live coding, and then a fit/behavioral discussion.

In system design, I worked through a problem tied to an existing feature on Booking.com. The live coding round involved solving an internal-style problem and included optimization questions, so I wasn’t just trying to get something working—I had to think about improving it as I went. The behavioral round then focused on my current role, how I handle conflict, and how I work day to day.
