The interview process is slow, methodical, sometimes intense, and more complicated than most people realize. Interviewers work very hard to ensure a good fit and strive to find perfect candidates appropriate for the position.

While they are human and certainly make mistakes, they go to great lengths to ask questions such as:

• Will this person not only do well but also be promotable?
• Does this person fit with the culture?
• Will they be happy working with the team?
• Are they up to the demands and requirements to be highly independent?
• Can they handle the stress that many Amazon jobs come with?

It's not just about technical skill or the ability to align your experience with the job description. All this can take time.

The pool of managers who will be interviewing you may also be interviewing dozens of others for the same or other positions, all while maintaining a heavy workload of unrelated responsibilities. These interviewers must coordinate reviews and agree that you meet all the areas they have decided to review, as well as your fit with the company's leadership principles.

Then, getting all these people on phone calls at the same time to discuss your candidacy is a challenge to coordinate.
