Credit-Card Approval Factors

When someone applies for a credit card, what factors would you use to decide whether to approve them? How would you judge whether their income qualifies?

Asked in the Interview stage. Original: 比如说一个人开通信用卡，你根据哪些东西判断是否能够给他开通？

Treat the decision as a measurable approval funnel rather than relying on a single rule. Explain which applicant signals you would use, how you would validate income, and how you would evaluate whether the policy is performing responsibly.

Requirements

1. Define approval rate and income verification pass rate.
2. Identify applicant factors and distinguish predictive signals from eligibility rules.
3. Explain how stated income would be verified and handled when evidence conflicts.
4. Describe risk, fairness, and quality metrics to monitor after approval.
5. Recommend how to segment and review the results.

Data Available

Application records, applicant-provided income, verified income documents or payroll signals, credit history, employment information, identity checks, approval decisions, account utilization, repayment behavior, and charge-off outcomes.
