The most ridiculous part then comes to the phone interview. The interviewer asked me questions about my undergraduate courses. The problem is related to linear algebra: How to tell a square matrix has a reverse matrix. I said I forgot it, that is five years ago. He said think about him, it has been 13 years since he was away from university. I said I took it in another language not English, and the terminology is not the same. I can pick it up very quickly if needed and I can translate it into English, he said It is no use of me if I cannot communicate with them in English. I argued back with that I just cannot remember what it is, but the ability to learn new things matters more. He said he just want to test the fundamentals of what I have learned, if I understand it thoroughly, I will not forget it. I said if you think about it in another way... He stopped me with no, he will not. And he will end this conversation because I am not suitable for a team work. And wish me a good future, and hang up the phone within 3 seconds. I did not even have time to say thank you! I learned a lesson from this interview: never argue back with your interviewer. He can hang up the phone whenever he can. That is kind of a power of empire. Also, I learned that not a single evaluation system is able to evaluate your ability except you. When I heard that I am not suitable for a team work, I was really sad. I have no idea that a company can really do this to their interviewee? People don't judge others in a way like this. I will move on to the future ignoring what he said to me. I am a grown-up not a kid. I need a reason to convince me if we were working in a team. That's it. If you don't convince me, I will argue with you, because we are in a team, and we are not working as a single person. If you argue back with no logic flow. I will convince you with mine. Clearly, this was killed by an empire, not a team work principle. This is actually the fact. We are working for other people, not ourselves. If you have your own company, you will have the power to recruit the people you think is suitable. That's it. But I hope that one day, when I was in a position like this interviewer, I will come back to read this article.
