RBC Customer Service Representative (CSR) interview questions

I applied to the collection department. It is a long process mostly when we are applying from within the bank. I met 2 recruiters but I was not given a detailed explanation of why I was not hired.

Started with a phone interview that lasted about 30 minutes- asked basic questions about my employment background and skills. Was told I would get a call back within 7-10 days. After nearly 3 weeks I called to follow up with them. Then I got an in person interview with 2 managers. Interview was sales based. Nothing too difficult. She said she would email later that same day so I had her contact information - she didn't. She told me I would hear from her by the end of the week - no call. I followed up mid week the following week and was given another date she would call me by - again, not call. If they can't follow through with a phone call commitment how will they follow though on development and work requirements??
