Start off by saying 'Hi my name is xxxxxx. And i just wanted to let you guys know that i am a person with stutter, so please bare with me when im taking my time. Appreciate you understanding it' I am a person with stutter and i have given around 20+ interviews in the past year. What helped me is, i hold on to some small object and press it hard when i stutter, so that my stress is directed onto that object and not my speaking. Make sure to give a pause for every 3 to 4 words such that you are in control of where you stop. As for the words you are struggling with - I have problem with words that start with D,S,T H and R and this is how i handle them. For 'Deep' i just say 'eep'. For 'recursion' i say 'ecursion'. I jusy skip that letter and pronounce the rest of the word in a way that the person im speaking with just assumes i said it right and they heard it wrong. Given that this is an interview and the person interviewing you has fair knowledge about data science, they will be very familiar with the words you are trying to get across and will understand them when you skip the first letter.
