I am currently a senior in the Department of Electronic Engineering and about to graduate. Even though I studied hard for my major, I didn't quite understand the terms in the job postings, and while I was worrying about my future career choices, I found out about this lecture. Thanks to the Top-Down teaching method, which first explains products used in actual companies in an easy-to-understand manner and then provides an overall flow, I was able to gain a great deal of understanding of the field in a short period of time. It also gave me the opportunity to decide how to proceed in the future. Thank you.
