The interview process at Swish Analytics is designed to evaluate your end-to-end modeling capabilities, theoretical knowledge, and practical coding skills. It is highly structured, rigorous, and heavily focused on hands-on technical execution.

The process typically begins with a 15-to-30-minute introductory phone screen with a recruiter or team member to discuss your background, interest in the company, and basic alignment with the role. Following a successful screen, you will be sent a comprehensive take-home data science modeling assignment. This assignment is the most critical stage of the process, typically requiring between 6 to 10 hours of focused effort. It involves working with a real-world sports dataset (frequently MLB pitch data) to build a predictive model from scratch.

Candidates who submit a strong, production-grade take-home assignment move on to a technical questionnaire interview. This stage consists of a deep dive into machine learning theory, statistics, and programming concepts. The final round is a comprehensive case study and panel interview. During this stage, you will present your take-home assignment, defend your modeling decisions, and walk through a mock data science scenario simulating the real-world challenges you would face on the job.

The visual timeline above outlines the typical progression from the initial touchpoint to the final decision. Candidates should manage their time carefully, particularly during the intensive take-home phase, as this stage serves as the primary gateway to the final rounds. Expect the entire process to move at a moderate pace, with proactive communication being key to navigating the stages successfully.

To excel in the Swish Analytics hiring process, you must master the specific technical areas that the team evaluates at each stage.

End-to-End Predictive Modeling (The Take-Home)

The take-home assignment is the cornerstone of the evaluation process. You will be provided with a raw dataset—historically focused on MLB pitch sequencing and pitch type prediction—and asked to build a complete predictive model.

The evaluation team does not just look at your final accuracy metrics; they assess your entire workflow. This includes how you clean and preprocess raw data, handle missing values, engineer predictive features, select and tune your algorithms, and evaluate your final model using appropriate validation strategies.
