Domain Expertise:

Business Acumen:

Knowing the business and applying data science to solve business problems.

Industry Knowledge:

Knowing the industry and its data challenges.

Other Important Skills:

Communication:

This one is for technical but also non-technical deliverables of the technical results.

Problem-Solving:

(e.g., strong analytical and problem solving skills to solve difficult data problems)

Critical Thinking:

The ability to think critically, objectively about data.

Curiosity:

Love to chew on the data and find those holy-grail insights
