1. Recruiter Screen (30 min)

• Introductory chat to understand your background and career interests.
• They’ll explain the process and ask about your availability.
• Sometimes a light behavioral question or coding warm-up.

1. Technical Phone Screen (1 or 2 rounds, 45 min each)

• DSA-focused coding questions on a shared editor (like CoderPad).
• Think LeetCode Medium/Hard — expect 1-2 questions per round.
• Interviewers look for: problem-solving, communication, and clean coding.

1. Onsite / Virtual Onsite (typically 4 rounds)

Usually consists of:

• 2 Coding Interviews
  • More DSA problems (trees, graphs, dynamic programming, etc.)
  • Think-aloud and communicate trade-offs
• 1 System Design (for mid-senior level)
  • Design a scalable system (e.g., news feed, messaging, file storage)
  • Focus on API design, data modeling, scalability, trade-offs
• 1 Behavioral (“Execution” or “Leadership & Drive”)
  • Meta uses structured behavioral interviews tied to values like:
    • Move fast
    • Focus on long-term impact
    • Be bold
  • STAR format is common (Situation, Task, Action, Result)

Given a stream of characters, design a data structure to check if any suffix of the stream matches a word from a predefined dictionary.
