Ways to improve tech skills?

I have a background in tech recruiting (about 6 years) but have not done *solely* tech in that time. I just had an amazing interview with a company who provided great feedback about my skill set as a recruiter, but ultimately went with a candidate that was a bit stronger in technical recruitment. Anyone know of any courses or online trainings I can take to brush up on my “tech skills”. Obviously as a recruiter I’m not looking to learn to code, but maybe something that is like tech recruiting for dummies so I can brush up on things I don’t work on daily anymore?

I’ve checked coursera but didn’t know what to search honestly, and I have technology made simple for the technical recruiter.

Thanks in advance!
