When posting these types of jobs, be as specific as possible to the needs and ask for examples of someone's work.

Consider posing a "What If" scenario and have applicants answer how they would handle it. This will give you a good idea of their skillsets, problem solving, and initiative.

Lastly, consider investing in a personality test / profile to determine of the applicant is a good fit.

I'm happy to expand, if necessary. Book a call.
