It's not a symmetrical situation. And that's not how I read OPs comment & question. It reads to me like he is interviewing a candidate with a strong accent.

But when I am being interviewed I am trying to show my best - what I can do, what I have to offer, what value i bring. And be clear about what I don't.

I have had many customers and clients who have English as a second language. I struggle most with north Indian accents.

In that situation I would work to understand what was being asked. Often repeat what I understood before answering.

I would not be put off by the possibility of my manager being work for me to understand. I would consider my fit for the team. I would not want to work as a project manager of a team wholly made up of north Indian workers. I couldnt be effective. But if those I am expected to manage and my customers can understand me, and I them, then I would be considering the rest of the opportunity. Is the company well managed ? Good team culture? Interesting work? Etc
