I applied through college or university. The process took 2 weeks. I interviewed at Meta in Feb 2016
Interview
We had back and forth emails where they asked for my resume and choice of domain, product or infrastructure. Then, they scheduled my phone interview. The phone interview was with a facebook engineer. There were two phone interviews but I didn't make it to the second one. The interview was 45 minutes long. They took 4 to 5 days to tell me I hadn't been selected.

Question 1
1. Asked me how to reverse a Linked List. Recursive Solution, Non-Recursive Solution, edge cases.
2. Given a matrix of 1s and 0s, find the shortest route between two points in the matrix while considering 1s as walls and 0s as traversable paths.
Recruiter call was pretty standard, first round was 2 Meta tagged LC mediums in 45 minutes. On-site was 2 coding sessions of 2 LC mediums, a system design interview and a behavioral interview with an engineering manager.

Question 1
How do you answer if someone asks how long a deliverable or project will take?
The entire process usually takes 3–8 weeks, depending on scheduling and the specific role. Coding interviews heavily emphasize common DSA topics such as arrays, strings, trees, graphs, BFS/DFS, heaps, hash maps, and dynamic programming. System design becomes increasingly important for E4+ positions.

Question 1
Given an array of integers and a target value, return the indices of two numbers that add up to the target
Unexpectedly, the first question in the technical round felt familiar. It was about finding a subset of strings with unique character concatenation — same problem I had worked through on PracHub a few days earlier. The interview included a recruiter screen followed by a rigorous pair of technical interviews where I tackled data structures and algorithms alongside system design concepts. After successfully answering a few more challenging DSA questions, I received an offer. The entire experience was intense but ultimately rewarding, and I happily accepted the position.

Question 1
Given an array of strings, pick a subset whose concatenation contains no duplicate characters, and return the maximum possible length of that concatenation.
