American Express Senior Financial Analyst interview questions

Applied on their careers site. A recruiter later contacted me about the role. We spoke about my resume and salary expectations. They later proceeded by scheduling interviews with 3 managers (for 30 minutes each).

I had an initial phone interview with an HR contact. There were so many moments of awkward silence after my responses that I tried to cut, but after a while it was out of control. I followed up our conversation with a thank you e-mail, and was expecting to hear back from her. However, after 2 weeks I still had not heard anything, so I reached out with an e-mail asking if there was any update on my status as a candidate. After over a week there has still be no response. In my opinion this is just unprofessional, and I would have appreciated even a system-generated e-mail stating that they were no longer going to pursue me as a candidate.
