I applied through university. The process took 5 days. I interviewed at Meta in Feb 2013
Interview
Pretty quick. I went through 2 on campus interviews. The interviewers were friendly, and did not try to intimidate you. I did not think I did very well, but I still received an offer by the end of the week. From what I got from it, they do not have a very high standard for highering interns, but when it comes to extending an offer at the end of the internship, they prune aggressively.

Question 1
Some string manipulation in Java. You have to know how to use StringBuffer's fairly well. Also, asked a lot of tree/graph related questions
I applied through an employee referral. I interviewed at Meta
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.
