i would say that especially for young applicants, you should be confident yet humble, leaving ppl an image that you are willing to share, to learn, and to be shaped.
SNAKE 加油!! Take it as an learning experience. With so many interviews coming up you will only do better. I did real bad in my many previous english job interviews as well, but I have learned to rephrase better and try to be more friendly with my interviewer. Be confident and good luck to you!!
I agree with you, but then just try to explain your thought and logic without making judgement on your interviewer first, avoid making other feeling uncomfortable.
