After the application, all applicants are invited to Amazon campus for interview. The interview is done only through online assessment. The online assessment contains both IQ test question and programming test. For c++ part, the programming test is using non c++11 compiler. The IQ test question is pretty easy, while the programming test could be hard if you did not know the problem beforehand, especially if you are familiar with c++11 features and try to use it, only to find it is not supported.

I applied through LinkedIn with reference. As usual, I received OA with middle LeetCode questions, which were pretty hard for me. After 4 month I was asked for Screening Interview, where recruiter explained me my interview path in 15 min. I scheduled my interview, but one day before I received an email about rescheduling and I was asked to give my schedule which I did. After one week I received another email, recruiter told me that the schedule doesn't work for them and I need to give another one (which is strange because I gave the whole week with business hours from 9 am till 6 pm). As soon as I sent my new schedule, I received the email that my position was filled already. This is the end of the story.
