Underdog Fantasy Data Engineer interview questions & guide 2026

The following questions are representative of the patterns observed in recent Underdog Fantasy interviews. Use these to gauge the depth of technical and behavioral proficiency expected for the Data Engineer role.

Technical Proficiency and Tooling

This category assesses your hands-on experience with the modern data stack, specifically your ability to implement and optimize workflows.

• Talk to me about your project experience with dbt and how the dbt setup was.
• Walk through your approach to designing a data model for a fantasy sports scenario.

Preparation for Underdog Fantasy should be focused on demonstrating both deep technical competence and a proactive, problem-solving mindset. You are expected to articulate not just how you build, but why you choose specific tools and architectures.

Technical Competence – Your ability to demonstrate proficiency with core tools like dbt is essential. You should be prepared to discuss your past projects in detail, focusing on architectural decisions and the trade-offs you made.

System Design and Modeling – Because the process includes a take-home assignment, you must be comfortable applying data modeling principles to real-world scenarios. Focus on creating clean, scalable, and well-documented models that reflect an understanding of fantasy sports data.

Communication and Professionalism – The interview process is an opportunity to showcase how you handle feedback and present your technical work. Be prepared to explain your design choices clearly and defend your technical decisions with data-backed reasoning.

The interview process at Underdog Fantasy is designed to be concise and focused on practical application. Candidates typically begin with a recruiter screen to establish baseline alignment, followed by a Hiring Manager interview that dives into your technical project history and fit. A significant component of the process is the take-home assignment, which serves as a technical benchmark for your modeling and coding capabilities.

Expect a process that values efficiency and directness. The team is looking for candidates who can demonstrate immediate value through their work on the assignment and their ability to articulate their technical philosophy during conversations.

This visual timeline illustrates the typical progression from initial screening to technical evaluation. Use this to structure your preparation, ensuring you have your project examples ready for the early rounds and your modeling skills sharpened for the take-home challenge.

Data Modeling and Architecture

This is the core of the evaluation. Interviewers want to see how you structure data to support complex business questions.

Be ready to go over:

• Schema design – How you organize tables for performance and readability.
• Data transformation – Using dbt to manage complex logic and dependencies.

As a Data Engineer, your day-to-day involves owning the data lifecycle. You will be responsible for building and maintaining pipelines that ensure data is available, accurate, and performant. You will work closely with product and engineering teams to understand the data requirements of new features and ensure that your models support those needs.

Typical projects include refining the dbt transformation layer, improving the reliability of data ingestion, and collaborating with cross-functional partners to solve data-related bottlenecks. You will be expected to operate with a high degree of autonomy, identifying areas for improvement in the existing data infrastructure and proposing technical solutions that align with the company’s growth.

A competitive candidate for this role possesses a strong foundation in data engineering best practices and a genuine interest in the sports/gaming space.

• Must-have skills – Expert-level proficiency with SQL, significant experience with dbt, and a strong grasp of data modeling concepts.
• Experience level – Demonstrated history of managing end-to-end data pipelines in a production environment.
• Soft skills – Strong verbal and written communication, the ability to work independently, and a collaborative mindset.
• Nice-to-have skills – Experience with cloud-native data warehouses, familiarity with real-time data streaming, and a background in sports analytics or gaming industries.
