This is a tough one man. Stuttering happens in the most unexpected situations. Yesterday I was ordering my usual drink at Starbucks..something I always say properly. But yesterday I couldn’t get the word Trenta out of my mouth. I was thinking wth is going on. Makes no sense. That being said..for interviews, although it’s tricky but you should come up with common/generic responses based on your previous interview experiences. Word play, practice and more practice. For example if you get stuck or think you will most likely get stuck in a specific word, have a backup and a backup for that backup. Preparation is the only option. Lot of casual pauses. Not sure if this method will work for you but try to answer the question like a story aka a start a middle and the end/conclusion. This will create a proper sequence and a flow in how you will break down the answer. All the best
