As a non-major, it allows me to learn about the tasks, work environment, mindset, and roadmap through which developers can grow as developers. In particular, as a job seeker, I have no choice but to consider realistic conditions, so it was good that the characteristics, differences, and pros and cons of large companies, SI companies, startups, and entrepreneurship were clearly explained. I recommend it to those who are seriously considering becoming a developer, as well as those who are trying to make a living.
