From a senior admin standpoint I always do two things when hiring a new Jr. Admin. I ask them to count to 5 and I tell them if they ever break anything to tell me the minute it happens and what they were doing.
I would rather them tell me quickly, fix and let it be a learning point with little repercussions on the first go round than have them lie to me and have to spend 8 frustrating hours trying to diagnose then fix the issue. I have fired people for that.
Now, can you figure out why I ask them to count to 5?
