SurePayroll User Interface Developer interview questions

It was a phone interview. The interviewer was a person of SurePayroll's Talent Acquisition. At first he asked me to talk about recent projects I was working on. Then, he asked about my previous experience (what I do in the previous company.) After asking me things about my past experience and projects, he let me asked him questions. I asked him what the exact responsibilities of UI Developers are at SurePayroll as it was not a common position that every company had. The job description included responsibilities that usually belonged to UX Designers and Software Engineers (SurePayroll also had UX Designers and Software Engineers). I wondered how this role collaborate with others. Unfortunately, the interviewer was neither a UX person nor a developer. He said it was clearly listed on the job description and read some of them to me. Kind of made me feel like he's saying I did not read it. After that, I asked him some other questions about the role, the team and the company. He did not know much about how the role and team worked. The interviewer's job was to gather more information and hand it to the hiring manager. The interviewer was friendly, but he had no UX background, which was the awkward point - the one asking your project detail was a person with totally no knowledge of your field.
