Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You're discussing past data science projects and want to explain not just which technologies you used, but how you handled issues when things did not go as planned.
What technologies have you used in past projects, and how did you approach the problems you encountered along the way?
