As a backend developer, I had been feeling that when updating my resume, it's important to show specific competencies connected to practical experience rather than simply listing technologies. This course was a great help in supplementing those areas. Thanks to the real-world cases and project-based explanations covered in the course, instead of simply writing "Java backend capable" on my resume, I was able to more clearly include how I actually utilized it in real situations and what problems I can solve. In particular, I was able to gain specific examples and thought processes that can be used during interviews, so I think this is a course that provided a clear direction for the overall job preparation process.
