Eventually you’ll get a “No” along with a message that, per policy, they don’t provide feedback. And then you’ll get several emails insisting you send your feedback, because they really want to “improve the process”. *facepalm*
Unfortunately, despite assurances to the contrary, I was generally unimpressed with the quality of the people doing the interviewing. One of them was in his kitchen, while family members moved about behind him. Another didn’t share video, because reasons, making every silence while they made their notes that much more awkward. And another would spend 2+ minutes typing in silence until finally asking the next question, ruining any opportunity for flow or conversation.
Judging by Amazon’s recent growth (prior to the recent layoffs), I’m not sure anyone has had time for any engineering. They’ve all been stuck doing interview “loops”.
