I applied through an employee referral. I interviewed at Meta
Interview
The internship application process was this: Resume Submission --> HR email requesting more information: grades sheet (I'm a CS student), if I were to join FB what would interest me most to be working on, location preferences etc. --> HR 10min Screening --> 45m Technical Phone Interview (if good --> 45m Technical On-Site Interview).
Interview questions [1]
Question 1
1. Tell me about yourself
2. Given each abc letter has a value (a=1, b=2, ... , z=26), compute the number of ways one can decode a given integer. e.g. 23 --> 2 [ 2, 3 ; 23 ], 456 --> 1 [ 4, 5, 6 ], 123 --> 3 [ 1, 2, 3 ; 1, 23 ; 12, 3 ]
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.
