I applied to the rol through a popular job portal. I got a call immediately from the HR asking me the particulars. The first round of interiew was subsequently set up with in no time. On the same day as the first round, the HR called and told me of my clearance to the next round. After a week, this round was scheduled. I heard no feedback from the HR for almost 2 weeks. On following up, they told me that I cleared this round too an set up an in-house interview. However, I received no further communication for almost 2 weeks. Again on following up, I was given a date. After 3 rounds, which were interesting, I was told that I would be updated the next day. After bamost 2 weeks, since I had not heard any feedback, I called them only to get a message that I was not through. Given the structure around the interview process, i would have expected more professionalism frm amazon on rejection and some feedback, in fact a mail communication would have helped.
