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.
Questions d'entretien [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。
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.
Standard cookie cutter interview with a coding interview, a system design interview and culture interview. The coding part is basically leetcode. The system design is what you can find on many youtube videos. The culture one is more tricky as they want to see that you fit Meta's culture, not that you were doing great at your existing company. So skills like dealing with conflict without calling in managers is sought after.

Question 1
coding: I forgot, sorry
system design: design ticketmaster
culture: talk about past project; when you disagreed with a peer; how I resolved dissagreements, etc.
The interview felt more straightforward than I anticipated for a well-known tech giant. After a recruiter screen, I faced a technical round that included a DSA question about finding the lowest common ancestor in a binary tree. I was pleasantly surprised when I realized the exact problem had popped up in the algorithm practice section on PracHub during my prep. Ultimately, the experience was decent, but I chose to decline the offer as it didn’t align with my current goals.

Question 1
Given a binary tree, find the lowest common ancestor of two given nodes in the tree.
