I interviewed for the packet forwarding team. The first round was a 30-minute introduction interview with the hiring manager. This was followed by two technical rounds of 45 minutes each on HackerRank, where C++ was to be used to solve the questions.

Technical Questions:

1. Create a function that returns true if the given node is valid in a binary tree.

2. Create a function that contains binary numbers in a LinkedList and returns the decimal values.

3. Few more whiteboard questions such as explaining the differences between vectors and Linked Lists, maps, hashtables, etc.
