American Express Analyst (Compliance) interview questions

Had a phone interview for the Compliance Analyst position which lasted about 20 minutes. The interview was conducted by HR and it was mainly behavioural type of questions. I was told that I would receive feedback by end of day the following day. Its been over a month and I haven't heard back from anyone at American Express HR despite multiple email follow up. Disappointed with the way they treat the applicants - least they could do is send the generic email rejection if they will not be proceeding with their candidacy.
