Amazon Engineering Position interview questions

A 1 hour phone screen, and then a marathon 4 hour in-person interview. The tone of questioning was adversarial and often the interviewer's response to my answers was dismissive or feigned disgust. The entire office was dead-quiet, with workers silently at their desks and only speaking hushed whispers. Bad vibes all around. One of my interviewers looked like he was being held hostage.
