I made it to the final round of Google's BOLD Internship program. It consists of two phone interviews, about 20-30 minutes each. Most questions were standard, with the exception of two "Google" questions mentioned below. The interviewers asked some questions specific to their product (e.g., "What would you change?), which is sometimes one of Google's more obscure products. One of my interviewers worked on Google Product Forums. Be very well-versed in their product line.
