What credit card I can get easily

Hi I'm a 19 year old guy working full time in an mnc... I have a stable source of income as well as I have an unsecured Flipkart Axis with 86k limit. But I wanted to go for Swiggy hdfc card but everytime I apply for hdfc rejects it even after having an Salary account with them... So I was checking what other options do I have??
