The most difficult part of preparing for employment was writing a resume. I felt that the coding test and other technical and knowledge parts increased in proportion to the amount of study, but in the case of the resume, I had a hard time just writing it. I took the class because I wanted to get a better opportunity with a better resume the next time I change jobs, and the lectures were very helpful and easy to understand because they gave many examples. I plan to gradually revise my resume based on the lectures.
