I applied through an employee referral. The process took 4 weeks. I interviewed at Meta in Nov 2021
Interview
I had a referral and was invited to apply. After waiting a few more weeks a recruiter reached out to me to set up the first interview. This interview lasted about 40 minutes and consisted of two technical questions. One Leetcode easy and one medium. I passed to the final round interview where I got two Leetcode mediums.

Question 1
They asked me to create a deep copy of a linked list with random pointers. Very similar to Leetcode 138 (https://leetcode.com/problems/copy-list-with-random-pointer/).

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.
