As a Data Engineer at Hulu, your day-to-day work is dynamic and spans the entire lifecycle of data. You will be responsible for:

• Designing and Building Data Pipelines – Architecting robust, scalable batch and real-time pipelines to ingest, clean, and transform massive streams of structured and unstructured data.
• Data Modeling – Developing clean, optimized data models and schemas that serve as the single source of truth for downstream analytics, data science, and reporting teams.
• Performance Optimization – Monitoring, troubleshooting, and tuning database queries and data processing jobs to ensure they meet strict performance and cost SLAs.
• Cross-Functional Collaboration – Partnering closely with Software Engineers, Data Scientists, Product Managers, and Business Analysts to understand data needs and build tailored solutions.
• Maintaining Data Quality and Governance – Implementing data validation frameworks, monitoring tools, and security controls to ensure data accuracy, privacy, and compliance across the organization.

To be highly competitive for the Data Engineer position at Hulu, you should possess a strong blend of technical expertise, systems thinking, and collaboration skills.

Must-Have Skills

• Advanced SQL & Database Design – Mastery of relational databases, schema design, query optimization, and performance tuning.
• Programming Proficiency – Strong coding skills in languages like Python, Java, or Scala for building data pipelines and processing scripts.
• Distributed Systems & Big Data – Experience with big data technologies such as Spark, Hadoop, Hive, or cloud-based data warehouses.
• Data Modeling – Deep understanding of dimensional modeling, normalization, denormalization, and data warehousing concepts.

Nice-to-Have Skills

• Streaming Technologies – Hands-on experience with real-time streaming frameworks like Kafka, Flink, or Spark Streaming.
• Cloud Infrastructure – Experience deploying and managing data infrastructure on cloud platforms like AWS.
• Ad-Tech or Streaming Media Domain Knowledge – Prior experience working with streaming metrics, video delivery data, or digital advertising systems.

Q: How technical is the coding round for Hulu Data Engineers? A: It is highly technical but practical. Expect a mix of software engineering coding (often in Python or Java) focusing on data structures and algorithms, alongside intense SQL query writing and optimization. You will need to write clean, syntax-accurate code on a whiteboard or a shared online document.

Q: What is the company culture like for the data team? A: Candidates and employees consistently praise the culture as highly collaborative, professional, and friendly. The team is composed of incredibly smart, passionate engineers who value mentorship and continuous learning. It is an environment where ego is left at the door and collective success is celebrated.

Q: How much preparation time should I plan for? A: Most successful candidates spend 3 to 4 weeks preparing. Focus your efforts on practicing live SQL query writing, reviewing database design patterns (especially for high-scale analytical workloads), and practicing algorithmic coding.

Q: Are there behavioral questions in the interview? A: Yes. Hulu values cultural fit and communication. You will face questions about your career growth, how you handle conflicts with teammates, how you prioritize tasks under tight deadlines, and how you work with non-technical stakeholders.

• Focus on the "Why": When explaining your past projects or designing a database, never just state what you did. Explain why you made those architectural choices, what trade-offs you considered, and why alternative solutions were rejected.
• Master the Scale Transition: Be ready for your interviewer to ask, "How does your design change if the data volume increases by 100x?" Always have a scaling strategy ready, such as partitioning, sharding, or moving to a distributed framework.
• Understand SQL Engine Differences: Don't just know SQL syntax; understand how different database engines execute queries. Know the differences in indexing, locking, and memory management between engines like SQL Server and Oracle.

• Practice Explaining Complex Concepts Simply: During your preparation, practice explaining complex technical metrics (like data skew or query execution plans) to a non-technical friend. If you can make them understand, you will ace the business communication rounds.
• Review Code Sent Prior to the Interview: If the recruiter sends you a code snippet or a schema 10 minutes before your phone interview, use that time to look for common anti-patterns: missing indexes, redundant joins, nested subqueries that can be flattened, or inefficient loops in the application code.

The Data Engineer role at Hulu offers an unparalleled opportunity to work on highly complex, large-scale data challenges that directly shape the future of entertainment. From optimizing real-time streaming pipelines to designing analytical databases that handle trillions of records, your work will have a massive, visible impact on millions of viewers daily.

To succeed in this interview process, focus on mastering database design fundamentals, practicing live query tuning, and refining your ability to communicate complex technical insights to business partners. Approach the interview with a collaborative mindset, show your passion for solving hard problems, and demonstrate that you are an engineer who builds with scale, efficiency, and business value in mind.
