X Software Engineer interview questions

It's a horrible phone coding interview. The interviewer is extremely cold with zero response to whatever I say. Also she kinda treated me as a very junior programmer that when I skipped some explanation for very basic stuff, she assumes that I don't understand. Very bad experience

It was one HR interview, with a few personal and carrear questions. One technical interview with a software manager, this was very nice we talked about system scalability and good code practices. And one code challenge, that wasn't long. After a few days that I sent the code challenge they didn't give me any specific feedback, just said that I wasn't approved! And when I tried to ask for more details they told me that they couldn't give a better feedback! Very frustrating, because the solution filled all requirements!
