I applied through a recruiter. The process took 1 day. I interviewed at Meta in Jun 2013
Interview
I was contacted by a recruiter via telephone. The phone conversation was simple enough to warrant a trip to the office. The office was nice- catered food, and unlimited soda and candies. The first round interview lasts about 1 hour and consists of questions (no surprise) asking about time complexities calculation and data structures. Make sure you at LEAST know tree traversals before you go into the interview. Given the short time limit, feel free to ask your interviewer for help to speed up your answering.

Question 1
Questions were purely academic, nothing unexpected.
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.
