I applied through an employee referral. The process took 5 weeks. I interviewed at Meta (Menlo Park, CA)
Interview
First an interview phone screen with a very knowledgable, followed by two phone interviews with current Facebook PMs. All the questions probed into how you thought about understanding users, features, technologies, and the vision you had for building things. People are friendly and smart but will definitely push you to justify your responses and be thoughtful.
They very much want to see how you think rather than have you talk about your CV.
There are specific interviews during the final on-site round covering (1) analytics, (2) usability and design, and (3) vision --e.g. what would you want to build if time/resources were not a constraint
Referred through a friend, phone interview first. Asked facebook product related questions, why facebook, why PM, normal stuff. Then skipped second phone screen to onsite interviews. 3 interviews, 1 logic based, 1 future trends based, and 1 product design based. The logic one was tricky but can be cracked with a little more prep.

Question 1
What would you do if Mark Z. asked you to investigate whether we should switch from low-res images to hi-res images for the whole app?
I applied through college or university. The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in Oct 2013
Interview
I reached out to my university recruiter and she promptly went through a phone screen with me to learn more about my background and my interest in the role. Towards the end of the conversation, she said she would feel comfortable passing me along to a product manager for a 45 minute phone screen.
The phone screen consisted of culture-fit questions (Why Facebook? What is something interesting about you?) and then moved on to product specific questions (What is your favorite feature of Facebook? How would you improve it?) I would recommend preparing a bit beforehand.
Finally, I was invited to their on-site interview which was probably the most fun PM interview I have had. They have three interviews that are focused on 1) future 2) reasoning and 3) product. Make sure you are structured and can tie everything back to Facebook and their core products.
Overall, I had a fantastic time interviewing here and although it did not work out in the end, the culture is fun, people are great and the campus is unreal!

What is the future of XYZ industry in 5 years? 15 years? How will Facebook factor into that?
