Amazon Operation Manager interview questions

Was Identified by a head hunter as potential candidate for Amazon. Attended a meet and great, and later scored a phone interview. All moved fast within days. Interview was routine, bland, situational questions with very little feeback. Interviewer appeared to be "going through the motions" of the whole process. End the interview in about 20 minutes.

There was a lot of follow up required with the HR for the round of interview, timings, date. They were not at all prompt. The interview was scheduled on a weekend. The interviewers were cold, too full of themselves, interruptive, lacked respect for the candidate. No arrangement for refreshment. No one met me to guide through the place. HR did not even meet me during the course of the interview
