I suppose it depends on what industry, and also where you're hoping to get hired? My undergrad courses might not have gotten me totally ready for an interview at a FAANG company (though it's been over a decade since I graduated!), but that also wasn't a goal of mine. And my undergrad courses did totally prepare me for a few interviews at very highly-respected companies, complete with job offers, without needing a lot of external practice.
