Is it hard to get into EPIK Korea?

I've heard a lot about EPIK Korea and how it offers a unique opportunity for English teachers to work and live in South Korea. But I'm curious, is it really difficult to get into the program? I've heard varying opinions, some saying it's a breeze while others claim it's highly competitive. Could you elaborate on the application process and what makes it challenging, if any? Are there certain qualifications or experiences that give applicants an edge? And what about the interview stage? Is it a make-or-break moment for potential EPIK teachers? I'd love to hear your insights.
