Amazon User Experience Designer interview questions

Applied online, got email to do the screening. Did the screening the following week, got reject email this morning. *Had a pretty negative experience and here's why* - There was NO confirm email of the interview details. For all the other tech companies I interviewed, they email you about when you gonna do the interview, how are you gonna be interviewed(Phone?Skype?etc), who's gonna interview you. For Amazon's interview, non of this happen. Everyone just go fill in a Google spread sheet and that's it. I consider this as very unprofessional. - I did phone interviews a lot, and this is the first time that I mostly can't hear what the interviewer's saying. The call quality is *very* low. I had to constantly ask interviewer to repeat the question. I'm pretty sure this is very annoying for her and for me as well. Amazon please use a better phone. - All the questions are behaviour question. I asked and I'm sure that the interviewer didn't look at my portfolio. Again, I consider this as very unprofessional. Designer interview is not the same as developers, or other positions. You really need to look at my portfolio and ask specific questions so I can explain my approach. For many other companies they usually send a senior designer to interview me, and specifically ask me to explain my design process. This does not happen with Amazon's interview. Amazon is a great company and I'm sure you guys did a great job, but in terms of the design position hiring process you really need to reconsider your approach.
