Referred by an employee, I got the interview after a remote programming test. It took about nearly 3 hours from the very beginning to end. It was a complete technical interview, with no discussion of anything else. Three engineers interviewed me. Mai

Language test with code challenge. Because my laptop encountered a power crash, but they never trusted my power crash. They only thought I submitted the result without inputting some of the code result. Phone call with a very rude voice of speaking.

First round: 2 coding questions using C. You need to have knowledge of basic data structures. Also, you need basic knowledge of computer networks and operating systems, especially regarding TCP and inter-process communication.
