I can see asking about previous jobs ending. That’s a given.
But “why did your internship end without you being offered a job?”
It’s weird to me in the sense it’s really a waste-of-time question, not a good question.
When I read it, it made me blink a couple times and the sarcastic answer that immediately came to mind was, “Because the semester ended?” - which will be the true answer 98% of the time. 1% might say budget, but I kinda doubt it. I’m guessing you wouldn’t be hiring the 1% sitting silent with a strangely incredulous look on their face. It’s all about being able to answer the question diplomatically, I suppose.
Time better spent finding out more about the takeaway the student got from the internship experience, since so few college internships these days are vetted.
Internships are not pipelines to jobs, at least not in graphic design, where a junior design position usually requires a 4-year degree and at least 2 years of professional experience. Those days are loooong gone, simply because there are way too many design students out there. That’s why I advocate students getting internships and work experience as soon as they can while still in school, not wait for their final semeser of senior year. Even a real part-time job at a printer will put a student above their peers in an interview (but try telling that to a student of design wanting to be creative…)
