Hi everyone,

I'm participating in the American Express Campus Challenge where we need to rank cardholders by estimated profitability using anonymized customer attributes (spend, revolving behavior, risk, engagement, benefit usage, etc.), but there's no profitability target provided.

Some questions I have:

How can I approach this problem from scratch?

Would you treat this as a scoring problem, an unsupervised learning problem, or something else?

Any papers, blogs, or similar case studies on customer profitability or credit card analytics?

Is there any resources for understanding about ranking?

I'd love to hear how experienced data scientists or product analysts would think through this kind of ambiguous business problem. Thanks!

I am from a non-circuital branch with a CPI of < 7.5 . I am aiming for non-tech roles and one concern I have is that I don't have any POR.

How important are PORs for non-tech placements?

AND

Do companies strongly prefer candidates with PORs?
