they did not really interview for a long time and ask many questions, so better prepare well since you only get 1 shot from the interviewer. Be aware to understand your applied role, and how your previous experience/ skills would be able to transfer to the internship. Also make sure that you understand well enough the background of the team, and ask questions that demonstrate your understand. It is okay to be subjective since it is also a way for them to understand your thought process.
