Amazon Software Development Engineer (SDE I) interview questions

I was interviewed by non-native English speaking SDE Intern. It was difficult to understand what he was saying, I asked him to repeat several times. In the end I understood the coding problem statement and I solved it. There was one behavioral question that I believe I responded well. The interviewer suggested that I qualified for a next interview phase and the HR will let me know when that will be. The HR reached out but the outcome was negative. Pretty tricky interviewer!
