It was pretty smooth. I met with 6 team members. Each interview was pretty grueling, but they are looking for willingness to solve a problem. I heard back from them in 2 days with an offer.

1. Code for counting the number of bits of a uint32 variable.
2. Code for a graph in C.
3. Is send() blocking until the data is sent to the server in TCP?
4. What is a bridge?
5. What does a bridge do?
6. What are various Layer 2 protocols, routing, and what does the data link layer do, etc. All theory about computer networks.
7. What is memory fragmentation?

OS questions:

• What is virtual memory addressing?
• DMA
• CPU scheduling algorithms
• Operating system functions
• Difference between processes and threads
• When would you use multithreaded rather than multi-process?

Finite automata:

• Write the state machine for a garage door.
