Most Data Science Tests Miss the Workflow
Focus only on coding, not thinking
Data science is more than writing functions
No exploration or experimentation

Candidates are not evaluated on how they understand data
No visibility into approach
.png)
You see final output, not the steps taken
Hard to evaluate modeling decisions
