The process took 1 day. I interviewed at Meta (Palo Alto, CA) in Aug 2010
Interview
A short 15 minute phone interview with a recruiter was followed by an interview with an engineer. I was asked about projects I had previously worked on and for examples of challenges I had to solve in them. Afterwards programming questions on algorithms with space and time constraints were asked and had to be solved in an online editor.

Question 1
Output a single linked list in reverse, in linear time and constant space, and recursively
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.
