You will get HDFC credit card within a week of application but beware. This bank does not want to grow their customer base but just want to make the money by providing cc to new customer and then levy unjustified fees.
I just made some international transaction worth 175000 and they charged me around 6000 for FCY conversion markup fee. when inquired about the same to customer care they just rudely answer "dena to padega na sir" what a crap.
BTW I know how to get my money back ;)
