I've never done one myself but if I'd been offered the opportunity I'd have taken it. I work in HR and quite a lot of my role consists of recruitment, if I had to decide between candidates for a role/interview then somebody who'd interned somewhere would definitely stand out.
Although it'll be a little scary meeting all these new people you never know when they might be able to help you out in the future, or where the internship could lead!
Enjoy your first day
