4 interviews, same feedback

They all had seen my work, and were familiar with it beforehand. In the interviews, I go through my work briefly, they give me the low down on their company and what they are looking for, and we go from there.

With the excepetion of one interview where it became clear very quickly that the interviewer didn’t realize I was a recent grad, all the interviews have gone well only for me to feel somewhat surprised when a few days later they cite lack of experience as the reason they went with another candidate. I’m not sure what’s going on, if its the ways i’m talking about my work, or the ways I’m talking about my experience, or the ways I am responding to their questions, but I’m obviously missing the mark somewhere.
