The process began with an online assessment covering networking, Linux, and coding fundamentals. This consisted of 15 multiple-choice questions (MCQs) to be completed in 16 minutes. Topics included TCP/IP, BGP, Python, and troubleshooting.

After passing, I moved on to two 45-minute technical interviews:

Coding Round: This focused on file handling, data structures, Big-O notation, and common algorithms.

Networking Round: This was scenario-based and covered optical networking, switching/routing, and L0/L1 troubleshooting.

Pros:

• Challenging but fair technical questions.
• Interviewers were professional and respectful.
• The process was well-organized and moved quickly.

Cons:

• No detailed feedback post-interview.
• Some questions were very Meta-specific with little public prep material.

Overall:

A great opportunity to demonstrate both software and deep networking skills. I would recommend preparing in-depth for both domains, especially optical layer concepts.
