Royal Caribbean Group highly values teamwork, clear communication, and a guest-first mindset. Demonstrate this by sharing examples of how you have influenced decisions, mentored peers, or aligned technical work with business goals.

The interview process for a Data Engineer at Royal Caribbean Group is designed to be rigorous but conversational. It typically begins with an initial recruiter phone screen to assess your background, alignment with the role (such as specific experience in real-time data or AI solutions), and location preferences for our Miami or Doral, FL offices.

Following the recruiter screen, you will typically face a technical screening round. This is often a video call with a senior engineer focused on foundational SQL, Python programming, and basic data modeling. We want to see how you think on your feet and communicate your technical decisions. The pace is brisk, but interviewers are highly collaborative and will offer hints if you get stuck.

If successful, you will advance to the virtual onsite loop. This comprehensive stage usually consists of three to four distinct sessions covering advanced system design, deep-dive coding, data architecture, and a behavioral interview with engineering leadership. What distinguishes our process is the emphasis on real-world scenarios—expect questions that mirror actual challenges we face, such as handling real-time event streams from IoT devices on our ships.

This visual timeline outlines the typical progression from the initial application to the final offer stage. You should use this to pace your preparation, focusing first on core coding and SQL for the early rounds, and then shifting your energy toward complex system design and behavioral stories for the final onsite loop. Note that exact stages may vary slightly depending on the seniority of the role, such as the Lead Data Engineer position.

To succeed, you need to understand exactly what our engineering teams are looking for in each specific domain.

SQL and Data Modeling

SQL is the bedrock of data engineering. We evaluate your ability to not only write complex queries but to design schemas that perform efficiently at scale. Strong performance means you can seamlessly translate business logic into optimized queries and articulate why you chose a specific data model (e.g., Star schema vs. Snowflake, or Data Vault).

Be ready to go over:

• Advanced Aggregations & Window Functions – Grouping data, calculating running totals, and finding top N records per category.

As a Data Engineer at Royal Caribbean Group, your day-to-day will be dynamic and highly collaborative. You will primarily focus on designing, building, and maintaining robust data pipelines that ingest data from a vast array of sources—including booking systems, onboard point-of-sale systems, mobile apps, and shipboard IoT sensors. You will be responsible for ensuring this data is transformed, cleaned, and made available in near real-time to power critical business dashboards and downstream AI Solutions.

Collaboration is a massive part of this role. You will work closely with Data Scientists to operationalize machine learning models, ensuring they have the feature stores and low-latency data access required for real-time inference (such as personalized dining recommendations for guests). You will also partner with Software Engineers and DevOps to integrate data solutions into broader product architectures and maintain CI/CD pipelines for your infrastructure.

A typical project might involve migrating legacy batch processes to modern streaming architectures using Kafka and Databricks, or developing a unified guest profile that updates instantly as a passenger interacts with different services on a ship. You will take ownership of data quality, implementing automated testing and observability tools to catch anomalies before they impact the business.

To be a competitive candidate for the Data Engineer or Lead Data Engineer roles at Royal Caribbean Group, you must demonstrate a blend of deep technical expertise and strong architectural vision.

• Must-have skills – Expert-level proficiency in Python and SQL. Hands-on experience building scalable data pipelines using Apache Spark (or Databricks). Proven experience with cloud platforms (preferably Azure or AWS) and foundational knowledge of cloud data warehousing.
• Real-time expertise – For the Realtime Data roles, production experience with streaming technologies like Kafka, Event Hubs, or Flink is essential.
