Are guest lectures from engineers and companies genuinely useful?

Guest lectures by engineers and companies can be useful because they may show how knowledge from classes is applied in real products, development work, and other professional tasks. They can also make workplace challenges, needed abilities, and ways of working more concrete, providing material for thinking about career choices. However, simply attending does not guarantee a benefit. The value depends on whether the topic fits the student’s field or interests and whether the lecture is connected to classes through questions, assignments, or discussion.
