I applied through a recruiter. The process took 5 months. I interviewed at Meta in Apr 2015
Interview
Started off with a basic screening test from a recruiter, basic programming questions that your really should know.
This was followed by two 1 hour Skype interviews, both interviews consisted of 1 programming question and then 15 mins chatting. The questions at this stage are very basic (arrays).
Final stage was onsite interview, 4 back to back interviews, these were a lot harder but with good revision easily passed. Just make sure you know your data structures and basic algorithms.
Overall best interview experience ever! everyone is amazing and you leave knowing this is the place you really want to work!

Other Software Engineer Interview Reviews for Meta
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.
