American Express Engineer- Mainframe -15002417 interview questions

It was a Panel Behavioral and Technical Interview with four people (2 managers and 2 techies). Managers told me that it's not horrible if I cannot answer all technical questions. Most important for them was to be assured that I am a good and fast learner. Both Managers looked friendly while techies were not. I've had a hard time catching up their accent and needed to ask them to repeat again. After first 5 minutes, I've understood that I will not be selected.
