Savvas Learning Company interview questions

Had a round of phone interview for few minutes in which I was asked if Iam okay with travel..I said Yes..Asked about my experience. I said I didnt have experience on the Sales Front, and was into curriculum design. The person said my resume will be forwarded to the hiring manager. No response for few days. When I politely asked, I was told the hiring manager did not choose my resume because they are looking for people with sales experience. I dont understand why there was a phone interview in the first place as my experience was already clearly mentioned in the resume. The process was confusing. They should have first selected resumes of interest and called me if at all they were interested.
