Meta Interview Process (Software Engineer)
📌 1. Application & Recruiter Screen
You apply directly or get referred.
A recruiter reaches out to discuss:
Your background and resume.
Role fit and level (IC3, IC4, IC5, etc.).
Timeline and next steps.
🧠 2. Online Assessment / Technical Phone Screens
Depending on level and role, you’ll face:
🔹 (A) Online Coding Assessment (often for interns/new grads)
HackerRank-style test (2-3 problems).
Focus on data structures, algorithms, edge cases, and efficiency.
🔹 (B) Technical Phone Interview(s) (1–2 rounds)
45-minute coding interview via CoderPad or Meta's internal tool.
Solve 1–2 Leetcode-style problems live.
Expect:
Strings, Trees, Graphs, Dynamic Programming, etc.
Follow-up questions and optimizations.
Clean code, communication, and test cases.
Interview questions [1]
Question 1
two coding questions. one is about palindrome. The other is a binary tree traversal question. DFS algorithm can handle it easily, In the context of a DFS (Depth-First Search) tree traversal, preorder and postorder refer to different ways of visiting the nodes during the traversal. Here's the distinction。
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.
