Applied online and was contacted for an interview in one week.

The first interviewer asked one hard coding question and many verbal questions, including some language-specific questions, security questions, and a system design question. (I had listed object-oriented design and security as my skills, so do not expect these types of questions in a typical internship interview.)

The second interviewer asked two questions: one basic string manipulation question and a good recursion question.

Both interviews lasted 45 minutes each, back to back, for a total of approximately two hours. Overall, both of my interviewers were very kind and helpful.
