What Happens Behind The Scenes

How To Prepare For Amazon Interview | Amazon SDE 2 Interview | Amazon Interview Process

Your recruiter is leading the process and taking you from one stage to the next. Here’s what happens at each of the stages described above:

  • After the phone screens, your recruiter decides to move you to the onsite or not, depending on how well you’ve done up to that point
  • After the onsite, each interviewer files their notes into the internal system, grades you and makes a hiring recommendation
  • The “Debrief” brings all your interviewers together and is led by the Bar Raiser, who is usually the most experienced interviewer and is also not part of the hiring team. The Bar Raiser will try to guide the group towards a hiring decision. It’s rare, but they can also veto hiring even if all other interviewers want to hire you.
  • You get an offer. If everything goes well, the recruiter will then give you an offer, usually within a week of the onsite but it can sometimes take longer

It’s also important to note that recruiters and people who refer you have little influence on the overall process. They can help you get an interview at the beginning, but that’s about it.

    Learn them.

    Learn and show you understand them. Connect your own experience with these principles.Explain how you apply customer obsession, frugality, bias for action or learn and be curious in youractual job. Doing this will prepare you for your interview.

    This is an important part of an interview because these principlesdrive our work every day in the company. Showing that youunderstand and follow these principles is key.

    Also, do not make up stories, be sincere, real. If you do not know something, say itand ask for more clarifications or to have another question to evaluate you. This is very easy for an interviewerto see when somebody is making up a story.
