I have hired for some of the top employers in the country for over 30 years, and can assure you that “membership” in these pre-professional clubs-- at least for consulting and I-banking- is absolutely not important except in the minds of the college kids who join these clubs.
You are better off having a real job which shows initiative, hard work, leadership and influencing skills than you are having a manufactured line on your resume about being the “events chair” for the consulting club.
Figure out a way for contact-less delivery for the local food bank near your campus? Hunger doesn’t stop for Covid. Now THAT’S impressive. Go to a monthly meeting to decide which corporate big-wig to invite to campus for a lecture? Yawn.
Can’t speak to med school. But my kids have oodles of friends in med school right now and they all did the “normal” things in college- volunteering in nursing homes, working with a professor on writing research grants, one worked as an LPN in a long term care facility to close to campus every Sunday for four years (that’s impressive- and she needed the money).
This seems like a tempest in a tea pot!
