I got 4 days notice for my first interview and the two days option to choose from. I login into hankerRanks and await as my interview joins me. He (assuming from his voice) didn't turn his camera on, so i never get to see the face. which kind of puts me on guard a little. He asked me a problem and said i didn't need to compile. I felt stupid because i really couldn't understand what exactly he was asking me. He was patient with me but NOT friendly at all (I was okay with that). he was quiet as i was thinking out loud the solution. he will respond only when i ask.
