Should I ask current students how often they actually interact with engineers from companies?

Yes, it is useful to ask. Find out whether interaction with company engineers occurs through classes, experiments or projects, internships, lectures, or other settings, and how often it actually happens. This can help you picture the learning experience after enrollment. However, the number of opportunities and how easy they are to join can vary by university, faculty, year, and student, so check both current students’ experiences and official information.
