Because my thumb was accidentally crushed by the machine, I could go to the hospital for surgery but I couldn't move. Can I still go to the company for an interview? Will it be laughed at by others?

You are injured at work, how can you be laughed at by others? And generally the other party won't see what's wrong with you. But before you go to the next company, you'd better get your questions done first. Try not to work in a factory if you can. Because working in a factory, there is basically no future.
