• Version Control – Best practices in Git, branching strategies, and collaborative coding.
• Documentation Standards – Writing clear READMEs, inline comments, and computational notebooks (Jupyter/RMarkdown).
• Advanced concepts (less common) – Building custom R packages, containerization (Docker), and workflow languages (Nextflow or WDL) for genomic pipelines.

Example questions or scenarios:

• "Walk me through how you structured the code sample you submitted. How did you ensure another researcher could reproduce your exact figures?"
• "Describe your approach to testing and validating a custom data preprocessing pipeline."

Cross-Functional Collaboration and Scientific Translation

You will be working with individuals who do not have a computational background. Your ability to act as a translator between complex data structures and clinical reality is highly valued.

Be ready to go over:

• Stakeholder Communication – Explaining statistical limitations and model assumptions to clinical PIs.
• Scientific Writing – Contributing to grants, abstracts, and peer-reviewed manuscripts.
• Prioritization – Managing competing demands from multiple research labs or projects.

Example questions or scenarios:

• "How would you explain a complex machine learning model's predictions to an oncologist who is skeptical of 'black-box' algorithms?"
• "Describe a situation where a collaborator wanted to run an analysis that you felt was statistically unsound. How did you handle the conversation?"

As a Data Scientist at Fred Hutch Cancer Center, your day-to-day work will be highly dynamic and deeply integrated with active scientific research. You will be responsible for designing and executing analytical pipelines to process, analyze, and visualize diverse biomedical datasets. This involves collaborating closely with laboratory scientists and clinical investigators to understand their research questions, translate those questions into statistical hypotheses, and implement the appropriate computational analyses.
