1) phone interview: 30ish questions about c, c++, threading, process and Linux. Not very difficult. Have a few doubts about 2-3 questions Afterwards get feedback within 2 one day and they would like to see me in a face 2 face interview 2) the face 2 face interview: very smooth. See two technical guys. One is mid-level one and another is senior. The interview process is quite smooth. But the communication seems quite one way. I kept talking about the solutions and they seemed not very certain about what they are talking about. The questions prepared by the junior engineer seemed not very well constructed. And he was not very catching what I was talking about and in the whole interview process he seemed to seek approval from the senior guy. Overall I thought I did very well in C++, well on C and OK with TCP/IP software application structure. Questions about c/c++, threading, process and Linux just as the phone interview. It lasted 1.5 hours. As told by recruiter that it should last 3 hours and should see 3 different group of people. It seems that it did not went well to me.

The interview consisted of two coding questions. The first was a LeetCode problem on counting ships in a rectangle, and the second was a find-path dynamic programming problem, also from LeetCode
