How to Pass the Booking.com Software Engineer Interview in 2026

The Booking.com DNA (TL;DR)

Booking.com values strong analytical problem-solving, data-driven decision-making, and a collaborative, humble approach. Candidates are assessed on their ability to deliver impact within a fast-paced, global e-commerce environment, often through A/B testing and iterative development.

English original + your local-language translation

Tech and global multinational interviews are most often conducted in English. For industries like luxury, finance, or pharma, the working language may be local. We show every question in English first — alongside your local-language translation — so you can prep in whichever language your interviewer ends up using.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Booking.com interview outcomes, avoid these common traps:

  • Not clearly articulating their own perspective or the reasoning behind it.
  • Not handling missing or ambiguous information gracefully.
  • Giving a generic answer not tailored to Booking.com or the travel industry.
  • Relying on a single point of failure for coordination.

Test Yourself: Real Booking.com Questions

Three real prompts pulled from our database.

Type · Algorithmic

Given a list of hotel bookings with start and end dates, find the maximum number of overlapping bookings at any given point in time. Assume dates are represented as integers.

Type · Code Clarity

Refactor the following piece of code, which calculates pricing for different hotel room types, to improve its readability, maintainability, and testability. Ensure edge cases like zero occupancy or invalid dates are handled robustly.

Type · Influence

Describe a situation where you had to influence stakeholders (e.g., sales, product, leadership) to adopt a new marketing strategy or approach. How did you build consensus?

  1. 2

    Type · Algorithmic

    Given a list of hotel bookings with start and end dates, find the maximum number of overlapping bookings at any given point in time. Assume dates are represented as integers.
  2. 3

    Type · Data Structures

    Implement a Least Recently Used (LRU) cache with a fixed capacity. You need to support `get(key)` and `put(key, value)` operations. `get` should return the value and mark the key as recently used. `put` should insert or update a key-value pair, evicting the least recently used item if capacity is exceeded.

    Type · Algorithmic (Hard)

    Given a list of cities with their coordinates and a list of flight routes between them (represented as pairs of city names), find the shortest path (in terms of number of flights, not distance) between two given cities. If no path exists, return -1.
  2. 7

    Type · Debugging

    A user reports that sometimes when they search for hotels in a specific city, the results page loads very slowly or times out. Here's a simplified version of the backend service code. Identify potential issues and suggest fixes.
