Interviewer was friendly we had a nice conversation a few minutes at the start to talk about your resume about 35 minutes for the question and a few minutes at the end for behavioral questions

I was interviewed for an IT help desk internship. Had initial phone interviews with an HR rep and the IT team lead. Was brought in a week later to the Centennial, CO location for a series of interviews that lasted almost 2 hours. Although the two interviews I had with the IT team went well, the following two interviews I had with a higher up in the company and an HR rep went poorly mainly due to their attitude and condescending demeanor. My education and past were questioned in a harsh manner because I was pursuing my IT degree online (like that's such a bad thing?) and because I had no past internship experience (point of going for an internship is to get experience you don't have in the first place). Overall, I got the vibe from them that I was an unworthy candidate from the get go after interviewing with the none IT-folks. A few days later I got the generic rejection email. Best advice is to treat your candidates with more respect and not make them feel unwanted or unworthy during the interview process.
