I know software engineers need English skills like reading, listening, writing, and speaking. However, I couldn't find precise information about the objectives and methods of learning English for software engineers.
One of my colleagues said, "The problem is that the students don't search documents written in English by themself. Once I give that document, they try to read it with DeepL."
Therefore, maybe it is important to give priority to documents written in English over documents written in Japanese.
