How do you effectively choose a real estate agent: The Real, Real Estate Agents?

[Jason Xenakis]

Hello folks. First post. Happy to be here. My wife and I decided to  start out of state rental investing in Columbus Ohio. How can one, who has only rudimentary knowledge in real estate without any boots on ground experience (read a few books), effectively choose a real estate agent? We are both physicians and relatively intelligent humanoids, but without knowing what you don't know, it seems a difficult task. Is it about first impressions? The vibe? What are some red flags? What nuanced questions can I ask? Thanks in advance!
