Logistics Health Incorporated Software Developer interview questions

I submitted an application line for a Software Developer position at LHI. The interview process was pretty basic. It consisted of two project managers from the IT department. The first part was a brief introduction by everyone and then the interview began. I was asked about my background and coursework in college. After the basic background stuff I was asked some database and programming technical questions. The questions were relevant to the job description, but the amount of technical questions asked was pretty high. At the end of the interview they asked me what I know about LHI. I found this very odd because I told them exactly why I wanted to work there at the beginning of the interview. After I gave them my answer they asked if I knew what they do here? I gave a brief description of what I believe they actually do, but it was not adequate for the interviewer. I was asked "did you even read about the company before you came here?" I found this extremely rude as I had just, in the introductions, told them what I liked about the company. It is unreasonable to expect an interviewee to know everything detail about a company.
