I applied through an employee referral. The process took 1 week. I interviewed at Meta (Menlo Park, CA) in Mar 2015
Interview
3 rounds: First round is a culture fit. The next two interviews assess your design thinking. You will do a live critque of a popular, non Facebook owned app. (I did Yelp). The final interview had me going very in depth about the strongest project in my portfolio. These last two interviews each lasted 45 minutes each (The last one went over a bit). Fantastic, friendly people. Ran out of spots for interns for the 2015 season, so my application is paused for the 2016 season.
Interview questions [1]
Question 1
Tell me the high level thinking behind your application
The recruiter is very supportive. First round is a deck presentation. Second round is full loop: deck+ BQ+ whiteboard+ app critique. The Overall experience is good, it takes around a whole month
Straightforward like any big tech interview, but long and intense. Formats are pretty standardized so it just takes practice. Questions appear like it's from a bank, so if you're prepared you should be fine.

Interview
I was reached out by a recruiter. Started with the recruiter call, then portfolio presentation, then full loop (Portfolio presentation - app critique - design challenge - background). They had very strong emphasis on design craft and visual excellence. Recruiter who helped me prep was very nice and helpful.
