Applied online. Got a form and contacted for an interview in 1 week. The first interviewer asked 1 hard coding question and lots of verbal questions; including some language specific questions, security questions, and a system design question. (I checked object oriented design and security as my skills, so don't expect these kind of questions in a normal internship interview) The second interviewer asked 2 questions; 1 basic string manipulation question and a good recursion question. Interviews took 45 minutes each, back to back, so total is ~2 hours. Overall, both of my interviewers were really kind and helpful.
