The first round questions that I designed then still hold true today. I was inspired by Joel Spolsky's 12 questions candidates should ask their potential employer before deciding to join back in 2000. It may be a little old in some circles by today's standards, but it is still insightful imho:
The Joel Test:
The neat thing about The Joel Test is that it’s easy to get a quick yes or no to each question. And that's what I needed from my first round interview questions that anyone, even a non-agile-skilled or non-agile-knowledgeable person could use. So I came up with 24 quick questions, and we got some truly great candidates making it through the face-to-face screenings.
One of the most (perhaps THE MOST) important things about an agile coach is their experience. Money can't buy experience. Reading about other people's experiences, or attending courses based on other people's experiences is not the same as having the direct hands-on "did the best I could with the information and knowledge I had at the time, and nothing worked...until...after much persistence and many failures something worked!"
All experience is relevant. I am wincing at how arrogant I was when I was younger thinking that attitude mattered more than experience. They are equally important - it all depends on the problem space and time! The thing about people without experience in a particular space, is that they don't know what they don't know. My 24 questions highlighted things that were relevant for the different openings we had going at various times. A quick 10 minute Yes/No followed by a few initial typical HR availability, package suitability, location, role etc matching minutes and wallah - 1x effective initial screening for very cheap!
The very few who made it to face-to-face interviews which were experiential and enjoyable for both the coaches and the candidates highlighted the right candidates each time! Happy daze! (especially compared to traditional candidate screening processes and pains)

I advise experiential interviewing during the face-to-face as it is a case of "under stress, we regress", and a lot of coaching can be quite stressful as very little is under the control of the coach who is at best influencing the situation! And any coach who has not mastered conflict management and resolution skills, personal attacks, helping people overcome their own anxieties etc can be quite damaging to your organisation.
f you're more focused on a coach who's technical background is less interesting, you could take a look at the coaching levels and the types of coaching and design similar Yes/No questions to try and understand the tangible hands-on experiences a personal, executive, soft skills, etc coach has.
I suggest at the beginning of the face-to-faces to do some spot-checks to check that whatever Yes/No questions you screened with were correctly interpreted, and that the candidate's response was accurate before proceeding into the simulation(s). Some people, you know, will say anything to get a role! :O
After the simulation assessment(s), ensure you and your assessment team form and document your own, subjective, fact-based, Delphi-style, assessments of each candidate.
My final question for the candidates: Ask each candidate face-to-face what their opinion is of the other candidates. You'll be or not surprised how many candidates know, or know of, the other candidates, and their face-to-face opinions can be quite informative! Also insightful is how they react to those coaches they don't know or know of.
So hopefully by now you have collected all the minimal data points to make a more informed decision about finding the right candidate - a round peg for a round hole / a square peg for a square hole - for your people's (!!) needs. Remember, past performance is no guarantee about future performance. But also remember this is a critical role to match the right person to - as any change agent will by the nature of the role be disrupting people's comfort zone(s). Including your own often.
Good luck with your search and selection process!
Lastly, please let me know how it all works out for you and your organisation. Remember the most important (top) line of the Agile Manifesto reframed is a bit like "we're doing it, and by doing it we discover new and better ways of doing it, and we share with others what we have learned so that we all benefit". That's "agile"!
