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.

Two coding questions.

One is about palindromes. The other is a binary tree traversal question. A 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:
