I have interviewed with lot of companies but never met unprofessional people such as at Amazon. During my onsite interview some people were nice but others were equally pathetic. The hiring manager thought that she had achieved a lot in her life and was literally yelling at me which was quite intimidating. Because of this I lost all my confidence and this was something I was not expecting from a company like Amazon. I felt like some untrained bunch of people were there to interview me. People at Amazon didn't have enough courtesy to at least introduce themselves or even turn their videos on especially in a video interview (I am not expecting a whole lot about their lives but the role with org and what they do is something every candidate would want to know). I was literally feeling like they were taking interview for the sake of taking it. Just a piece of advice for Amazon train your employees on how to meet new people who can be potential employees and if you invite someone for interview please try to respect them. Candidates invest a lot of time and energy in your process so try to make an experience for them as well even if they do not get selected. Train your employees with some leadership principles first and then expect from candidates.
