Amazon Operations Manager interview questions

Phone interview. morelike a screen interview. Basically went over my resume and then gave an overview of the job, expectations, works schedule, etc. It wasnt with any of the employees at the location where I applied.

Contacted via email by internal recruiter, personality and simple math tests in application stage and prior to phone interview. Two separate recruiters contacted me. Phone interview lasted about an hour, additional math test during phone interview. Recruiters provided great information about the company and interview. Interview seemed to go well but ultimately did not receive an offer. A lot of time spent on interview/application process for no offer. Interviewer was in different state and did not know a lot about position or location he was interviewing for, a lot of canned corporate lingo. How can this person evaluate a position he doesn't know about?
