There's a lot of elements to typically cover in these questions, clarifications, scoping, making sure you're answering the actual question the interviewer is looking for you to answer, etc.


Could be worth doing a mock interview with one of the Prepfully Dropbox  Software Engineering Intern experts... they've worked in the role so they clearly know how to get through the interview.
