Fiserv Customer Service Representative (CSR) interview questions

There were two phone calls from different states, The first one was basic call explaining the job description, asking how much I expect to get paid. The second one was more of a behavioral. Both of the people sounded good and nice on the phone. They both said I can contact them if I have any questions. However, I followed up with them they didn't like it. They never informed on how much time it would take for them to respond, neither did they explain what would be the next steps. It took them 3 weeks to say NO. I wonder where do all of these good reviews come from rating this company good.
