I give my interview in AMEX in December 2018. There were 1 written test, 2 F2F technical rounds. Then one interview with VP. Then one HR discussion. This complete discussion took around 1 week. I had cleared the interviews, but salary they were offering was very very less. Around 20% hike or even less. They were not even ready to negotiate. Looks like that particular LOB is not that good, else what I have heard AMEX is good paymaster. Anyhow, I declined the offer(merely an offer).
