My interviewer speaks really fast. I have a hard time understanding what he is saying. How do I politely let him know that I am confused? I know I will have another interview with him soon and I want to be ready.

You can say, “I am sorry. I didn’t catch all of your questions. Can you repeat them?” You could also ask them to clarify their questions. “Would you mind clarifying the question? It sounds like you are asking me this. Is there something else that you want me to answer as well?” Since the interview is being conducted remotely, you can mention that the Internet cut out or it was garbled, as well.
