Certegy interview questions

Interviewer explained the company and position, then asked a series of pretty data scientist interview questions. Things about different metrics, types of models, SQL joins, etc. Then he went through a fairly simple business case that involved several calculations about credit card balances, usage fees, and interest from the financial institution standpoint. It felt more like a math or finance test than a data scientist interview up until the last question, which was if I wanted to test different strategies how I would go about doing so.
