How do you feel about the large number of civil engineering graduates not working in their field?

It's normal.

Not only civil engineering graduates, most of them do not work in their specialty. This phenomenon also exists in other professions.

For example, I majored in journalism, and now I'm in education, and I'm not in my field. And very few of my classmates are in journalism, very few. Most are also in the education or government industry.

In fact, I think the cause of this problem should be the concept of the problem, not to learn what specialties must be engaged in a certain work. People are in constant understanding, constant choice. Into the industry to see the internal may not be as good as the original, this may also be why most civil engineering graduates did not engage in the work of this specialty.
