1. Reasonable curriculum: Chalk Education has set up interview classes with different difficulties for different exams such as civil servants and institutions, covering all aspects of self-introduction, case analysis, oral English and so on, in order to help candidates improve their interview results and competitiveness, but Shanggan Village is still slightly insufficient.

2. Experienced teachers: The teachers in the chalk education interview class are all teachers with rich teaching experience. They are familiar with the form and content of the exam, which can help students understand the requirements and grading standards of the exam and provide effective guidance, but the experience of teachers in Shangan Village is slightly inferior.
