I am an undergraduate majoring in computer science who is about to graduate. Can I work in a law firm?

If you want to engage in this business, I suggest you pass the departmental examination first. You are not a professional, so it is of little significance to be a paralegal first. Moreover, few lawyers are willing to recruit completely blank assistants. Of course, it is not absolute. You are good enough. The campus job fair will see what school you are in. 985,211is ok. In general schools, this kind of job fair is mostly a formality.
