From my personal experience, this is a sign. As for the specific content of the sign, different people have different views. Because personally, I have been working in human resources for a short time, and I will mark some resumes of candidates who I think are not bad.
But my colleagues like to divide the candidates into different grades according to their own wishes and subjective judgments.
So don't worry too much. Anyway, the result of this interview was decided at the moment you finished the interview, so instead of worrying, think about your failure. What is not done well? What do you think is more effective if you do it all over again?
