It appeared that the internship coordinator was not aware I was coming or how many interns they had that day coming for interviews.
I arrived 15 minutes early, noticed them and ended up waiting 25 minutes past my scheduled time (so 40 minutes in total) to be interviewed by a scientist (who asked me, “oh I just saw you, does anyone know you are waiting?”), then the internship coordinator, who did not seem to know what the previous interviewer had asked me.
Overall, I feel my time was wasted and their process was not organized.
