I applied through an employee referral. The process took 4 weeks. I interviewed at Meta (New York, NY) in Oct 2013
Interview
I speak here for the off campus hiring process for students in universities outside of United States. The interview process consists of an offline programming exercise on the website InterviewStreet. The same leads to 2 (or in some cases, upto 3) phone interviews all coordinated by your location's recruiter.
The interview process is very flexible and the dates can be easily set up around your schedule. It took me a little over a month to go through the entire process although the same could be wrapped up within 2-3 weeks if one desires.

Question 1
Besides general algorithmic questions, we also discussed my past experiences in related fields, technical challenges I faced during the same, etc.

Interview
I was invited to take their OA about a week after applying, mostly consisted of leetcode easy and mediums. It was a pretty smooth process, with quick feedback. Good experience overall

Question 1
Data structures and algorithms, leetcode style medium and easy
They ask the normal standard DSA questions that you would expect for an internship like LeetCode mediums. I think there were two rounds of technical interviews before the offer stage.
DS&A questions, interview is just that with only a couple mins of non technical. Need to be quick and fluent in standard leetcode easy-med, and have decent enough grasp to come up with good ideas to approach leetcode hards.

Question 1
DS&A. Asked about how to merge 3 ordered array into ordered array. Then, how to generalise for k ordered arrays. Was okay, but need to be faster and have solution down as if you can do it in your sleep.
