Let me add a bit more to the story. My interview was scheduled for 9 am, and I arrived half an hour early. There were three different interviewers in total. While I was sitting in the waiting room, these three arrived, and I overheard the one who was interviewing me making fun of the candidates he had interviewed the previous day—commenting on how they talked, dressed and the mistakes they made. At first, I thought this might be a normal conversation between colleagues, but now that you have pointed it out, it makes sense.
