Applied online in late April. Received an email from HR recruiter in Seattle for scheduling a quick phone screen. Recruiter set up a ~20-30 min. call with the department head in the Palo Alto office for the following day. After that call, scheduled an 1.5 hr interview with 3 people (30 min each) I would be working with via video chat. Each asked pretty standard questions, nothing out of the ordinary and was more like a conversation than an interview. Received an email from the recruiter the following day telling me she had an update and called later to give me my offer. Entire process from applying online to receiving offer took less than 2 weeks. Fastest turnaround I've seen for any company's internship application process.
