TandemG Software Engineer interview questions

Two people interviewed me, they asked me 2 technical questions. They were very nice and re-assuring, and the questions were well described. I recieved a phone call for next interview after a few days

I went through 5 interview stages: online test, team leaders, division supervisor, HR and CEO. They were looking for knowledge in C/C++, data structures, OS principles, memory allocation, concurrency, and more.. In general it was good vibes and the HR interview was very cheerful and straightforward
