What is the acceptance rate for EPIK interviews?

Can you tell me more about the acceptance rate for EPIK interviews? I'm particularly interested in understanding how many applicants typically get invited for an interview, and what percentage of those interviewed ultimately get accepted into the program. Additionally, are there any factors that seem to influence whether or not an applicant is accepted, such as their teaching experience, qualifications, or the subject they plan to teach? I'm eager to gain a better understanding of the selection process and what I can do to improve my chances of success.
