I would try teaching/coaching them on,
How to Sharp their Skills: From my experience I have seen, learning first time for a specific skill is easier. However staying sharp and relevant on it is, challenging and an art at the same time. I would have some mentorship to keep this going with the interns.
Patience: Many of the Interns I deal with lack it initially. Nothing to blame. It's excitement, ignorance, tendency of jumping the gun, enthusiasm all can cause it. We need to teach them to have Patience for the outcome they are looking for.
Not to have Fear of Falure: Need coaching to make them realize, Falure is inevitable and how to gain the mindset to come out of the Fear of it!
Learn to Say NO: This one is subjective. But I would encourage interns to say No when relevant and gradually learn, when to say NO.
All the best to you and the Interns! 👍
