Biggest Challenges w/ Data Modeling?

Calling all data pros (data scientists, analysts, data engineers, data architects, software engineers in data, etc.)!

I'm doing some exploratory research on ways to help data pros with data modeling in the realm of data science and Big Data.

Would anyone be available for a 30 min video call to talk through your pain points? I'm especially interested in feedback from those just starting their data careers. I'm conducting user research to come up with tools and processes especially to support juniors.
