Don't worry! Excellent communication skills doesn't always need to be speaking fluently without breaks. It can also be communicating an idea to someone short, crisp and understandable. This is a trait that many fluent speakers lack. Trust me, you will feel free about the stutter during the interview. I know for a fact, they are never going to eat us, unless they are different, I hope not.  I would always think that, I can fail for a million times but I would never want myself to step back. This is our life! Take it simple:) Just my opinion btw 😊
