Meta Full Loop E5 Bangalore - Interview Experience

Current Organization: Tier 2 Retail Firm
Position: Senior Software Engineer

Round 1: Coding

1. Next Greater Number
2. Equilibrium Index in O(1) Space

Round 2: Coding

1. Moving Average in Every Window of Size k
   • Then moved to an iterator-based stream:
     • Print Summaries for Every Window in an Unlimited Stream
2. Clone Graph
   • A lot of discussion on corner cases, cycles, and handling other related concerns.

Round 3: Product Architecture

Design an Audio Channel System (version 2.1 to 5.1):

1. Identify all the subsystems
2. Ensure compatibility with multiple operating systems
3. Should support platforms like WhatsApp (audio/video), Facebook live, and Instagram Reels
4. Considerations for live streaming and similar use cases

I struggled in this round, particularly with designing client interfaces like codecs, handling multiple operating systems, and designing hardware interfaces.

Round 4: Pirate Round (Behavioral)

The interviewer asked a lot of questions about my past projects and achievements. However, it seemed like he wasn’t fully convinced by my responses.

Round 5: Coding

1. Merge Two Arrays with O(1) Space and Linear Time
   Example:
   [1, 2, 5, 0, 0, 0]
   [3, 4, 6]
   Output: [1, 2, 3, 4, 5, 6]

2. Power Function (a^b) in O(log b) Time with O(1) Space

Final Verdict: Rejected

Unfortunately, I didn’t perform well in the Product Architecture and Behavioural rounds.
