Portfolio Analyst

I was contacted by a recruiter about the position. After few days I was scheduled to interview with a portfolio manager. After that, I meet with another portfolio manager. Both went well. A I was scheduled to talk with the regional and nationals leaders of the portfolio department. In total, I had 5 interviews with them and I learned a great deal about the company. After the interviews, they told me that I am going to hear back within one week. After 2 weeks, decided to contact the hiring manager as I did not hear from the Bank. Silence Radio. I followed up with the National Director and a VP. Still nothing. 3 days later, the HR contacted me to let me know that I was not selected. I understand that they didn't chose me but ignoring my emails is lack of respect to myself as I spent 1 and half months talking to me.
