I had an interview with the STTD team at Intel.

It was a four-round interview for the software+hardware engineer position. The team's work involves employees in lab work and software development jobs.

They asked me questions on:

• Computer architecture
• Operating Systems
• Software development
• Simple circuit analysis
• C++

Circuit Analysis: With a simple resistor, ammeter, and diode, I was asked to check if the diode is forward-biased.

Computer Architecture: Virtual memory, the difference between RAM and ROM (including their advantages and disadvantages), caches, levels of caches, the purpose of multiple cache levels, and cache coherency.

Operating Systems: How processes communicate, and the differences between multithreading and multiprocessing.

C++: Pointers, references, and object-oriented concepts.

What is cache coherency?

How is it maintained?

How do processes on a processor communicate?
