Junior IT Support / Sysadmin

The company I work for (a law firm of about 120 users) is going to hire someone else than me for the first time next year. I'm very excited, this is part of a trend initiated by the higher ups that understand the needs for innovation and a well managed infrastructure.

For three years I've been alone with an MSP as a backup but for the first time I'll not only be in a team, but I'll lead one.

I know the kind of profile we're looking for : I want someone curious, with little experience but great passion, something I had when I started. I was lucky to have great mentors and I wish I will be one for that upcoming team member.

My question is this : how would you lead an interview to find that kind of gem ?

I had already thought of a few things but I'd be curious to hear more from my peers :

\- Ask a few technical questions, and focus on HOW the applicant handles it rather than the actual answer.

\- Ask about the applicant's personal projects if any. I hope I'll stumble upon the "well with my friends we wanted to play X and Y game so I made us a server with an old potato sitting in my parent's garage".

\- Ask hypothetical situations about handling difficult / stressful situations and giving the bare minimum info to the applicant, to see if they have basic understanding of looking up answers

I wonder what else I could do conduct an interview like this, Any suggestions ?
