1. I opened an HDFC current account, and after 5-6 months of (heavy usage) (no balance maintenance), I got a Business Moneyback card under my personal PAN pre-approved.
2. Opened an Axis priority account, and an SIP with axis MF a week after account opening. 2 months later (little to no usage) (no balance maintenance), I got axis Flipkart card and axis aura, it was not pre-approved but the bank agent called me informed I might be eligible so I should give it it a try, after applying got the card approved instantly.
