Amazon Project Manager interview questions

Initially, a recruiter reached out with regard to a Sr. Manager, asking that I apply if interested. An immediate response to my application was received with an assessment required. Following the assessment, the recruiter immediately reached out to invite me for a phone interview. However the invite was for a a Manager positing, different from the original he had shared and I applied. Immediately following the phone screen I was invited for a series of 5 video interviews with a request for availability and a list of questions requiring a response. A response was shared. This invite was received on Friday. Five days later, on Wednesday, the recruiter emailed to advise that the position had been filled. By far, the most unprofessional performance I have ever seen by a hiring team. Do better.
