A list of characteristics a candidate should look for in examiners is very short: do they have PhDs in a relevant area? Do they have enough post-PhD experience and training?
That’s it. After that you and your supervisor are not looking for the best examiners: you’re trying to find examiners who are available and who are best for you.
What attributes would your ideal examiners have? Would they be people whose work you’ve cited? Would they be people who do similar things to you? Would you want someone with a long career and significant expertise? Or someone who has finished their own PhD in the last few years?
You can’t find examiner perfection, but you can find “good for you” if you reflect on what you think you need, ask the right questions and explore who might be available with your supervisor.
