Some people say that "seeing words is like seeing people" has some truth, and a person's handwriting will reflect a new internal quality to a certain extent. But this statement is not necessarily completely correct. I can also see that some people do well in their own careers, but not necessarily how well they write. I can see that you are a very careful person, and you care about this detail, so I want to foster strengths and avoid weaknesses, just like several things mentioned upstairs. Well written, of course good handwriting. However, if the employer does not require it, your own handwriting (or calligraphy) is not necessarily one of your strengths. It is best to print it so that others can see it at a glance. Wish you success!
