College students are laughed at when they go home.

I think there may be something wrong with your behavior in the company, whether you are arrogant or not, and although you have a high degree, you may be a little stretched in the practical application of your work, so you may feel that someone is laughing at you. This is not meeting the villain, but your inexperience. The person who laughs at you means no harm. They should kindly remind you, try to get along with them and let them teach you some work experience, and you will get better gradually.
