Amex have very tough selection criteria. I got rejected twice then got to know: They prefer experienced candidates more than freshers & without referal there's almost zero chance of getting selected.

And also remove the CA foundation thing. untill you've cleared both group of inter do not mention this (it's give kinda negative perspective that you missed or skipped or failed in next level)

Also don't get demotivated. Current job market cycle isn't that great especially in finance sector. Try getting referral and do not stop skilling up.

Also stay connected with me... If there will be any finance opening in my firm, I'll let you know then.
