For shortcomings:
First, don't be too direct, you can be a little vague. For example: "I am too confident and easy-going, and I look weak."
Second, talk about some commonalities, not your own subjective deficiencies. For example, as a fresh graduate, you can say "lack of social experience", "work ability needs to be further strengthened" and so on.
Third, talk about some unimportant shortcomings, such as "insufficient theoretical research", "insufficient grassroots" and "there is still a certain gap between theoretical knowledge and practical work".
Fourth, the shortcomings created by personality can also be simply described, such as "introverted personality" and "inarticulate". ....
Of course, the most important thing is to have a good template to show, you can refer to the template of office resources and have rich materials.
