Interview
The first interview was a 45-minute technical interview. I was asked about concurrency and pointers in C++. Then, there were some questions related to my CV (my projects and previous internships).

Then we moved to fundamental questions about Operating Systems (memory management) and Networking (TCP/IP). The interviewer was knowledgeable
