Interviewing

Review the Amazon Leadership Principles (LPs)- These are used every day at Amazon and are the basis for many of the questions you will be asked during your interview.
Behavior Based Questions - Be prepared for behavior-based questions (e.g., "Tell me a time when..."), that often will be grounded in Amazon LPs.
Re-review the Job Description - Keep in mind the Basic and Preferred Qualifications as you embark on your preparations.
Aggregate your anecdotes - In anticipation for behavior-based questions, often grounded in Amazon LPs, aggregate multiple examples from your current or past roles that demonstrate your strengths. You may get questions that have some overlap, so it is best to have more than one example to highlight your strength in those areas. Don't over index to Amazon LPs, you will not be asked "Tell me a time when you needed Bias for Action", instead you may get a question about a time when you needed to make a decision or take an action quickly without time to fully analyze the situation or collect all the necessary data.
Functional Competencies & Experiences - While behavior-based questions grounded in Amazon LPs will be a large part of your interview(s), also be prepared to discuss your functional experiences and competencies. For a technical role (e.g., Cloud Consulting) you will most likely be asked about your coding/development experience - be prepared to talk about a specific programming language you are familiar with, for example. For a non-technical role (e.g., Engagement Manager) be prepared to talk about functional program/project management such as how you identify and manage risks on your projects, manage scope, manage/forecast costs, etc.
Outline these in STAR format - To answer questions most concisely and effectively, Amazon expects you to use the STAR format (S=Situation, T=Task, A=Action, R=Result) to structure your responses. Take what you have learned from the Amazon LPs, overlaid with anticipated behavior-based questions, and structure your anecdotes using the STAR format.
Prepare for Common Questions - Most interviewers will ask for an introduction or "Tell me about yourself"; have 3-5 sentences pre-prepared to highlight items you want to call out, be concise, and have some uniformity across the folks you speak with. I personally have used: Who I Am, Experience Highlight (2-3 concise items relevant to the role I am interviewing or), and Why I am Here.
Presentations and Whiteboarding - Some on-site loops require a presentation or whiteboarding session - work with your assigned recruiter to fully understand the requirement and position yourself to best satisfy the request.

For Whiteboarding, whether using a virtual whiteboarding, pen/paper, or an actual whiteboard, test it out in advance to ensure you are comfortable with the format and that someone on the other end of a videoconference can adequately see what you are doing. Be ready to go to a 200-300 level depth of your solution, the interviewer is going to expect more than surface level knowledge of what you are presenting (e.g., drawing a VPC with private/public subnets, be ready to explain what would go into one vs. the other and why - this may also lead to questions on how would the two talk to one another if required).

Likewise for Presentations, ensure you know how to screenshare (see Desk and Computer Setup below) in advance to avoid elapsing limited time with your interviewer(s) trying to work through it for the first time. For presentations, do your due diligence of what is best practice to include in the presentation (e.g., for a simulated project kickoff, you may be able to reference the Project Management Institutes templates and best practices for what should be included, overlaid with what you have traditionally included in your experience. The content and structure of your presentation may go a long way. Do not over index on making it visually appearing but do put forth some effort to have it be professional visual quality (e.g., would you use the slide deck to present at your current job).
Create a Cheat Sheet - A lot of interviews are virtual now, which gives you the advantage of creating a cheat sheet to quickly search and find examples to questions. While you should not look up each question, nor do you want to sound scripted, it is fully appropriate to reference notes. I would advise avoiding having your notes in a narrative format that one may take longer to skim and read and two may make you sound scripted. Instead have an enough data to jog your memory and help keep you responding in STAR format.
Desk and Computer Setup - With many interviews occurring virtually, ensure you have a space planned that is free of distractions and background noise if possible. While Amazon Chime (the platform used for audio/visual conferencing for Amazon Interviews) does a fantastic job filtering out background noise and allows you to blur your video background; at minimum those background effects will distract you and at worst make it difficult for the interviewer to hear or focus on you and your anecdotes. Try to test out Amazon Chime in advance to ensure you know how to navigate the application (e.g., Mute/Unmute, turn on/off your video, screenshare). For MacOS users in particular, if you will need to share your screen as part of a presentation, additional permissions are required in your OS Settings.

Web Cam: Make sure your webcam is placed on the screen you will be using to see your interviewer. While not something that will directly impact the outcome of your interview, nothing feels more disparate of an exchange when you are speaking with someone, and they are constantly looking away from their camera and you are getting a frequent side profile of the individual.

Microphone: As mentioned, Chime will typically filter out some background noise, but make sure you test out your microphone with friends, family, or your interview coordinator; particularly if you don't often use the setup you are using for calls in your current job. While poor audio quality is not a reason for an unfavorable interview outcome, it does increase the ease of which the interviewer can hear and speak with you when you have a clear microphone free of muffling, static, etc.
Interviewer Due Diligence - Recruiting may not always offer the first and last name of those participating in your interviews, but if they do, spend some time using LinkedIn, Google, etc. to do some due diligence. Understand who is in the role you are interviewing today, who is an internal stakeholder, etc. While there will be no bonus points for shared personal or professional connections or past employment overlap with your interviewer, it may still be something that increases your confidence and familiarity with the folks you will be spending time with.
Prepare Questions - Use the job description, what you have gleaned from conversations with recruiting, and from your interviewer due diligence to form a pool of questions. For those in the role today, you may ask "What does a day in the life look like?", "What does a great day in this role look like?", "What does a bad day in this role look like?". For the hiring manager, you may ask "What are on-site requirements of this role?", "What are qualities, characteristics, or behaviors of higher performers in this role?", etc. If it is an internal stakeholder, you may want to ask, "How would I best support you if offered this position?" rather than "how might I work with you?".
Day Before/Of Interview - Get plenty of rest, stay hydrated, and try to relax; you have put forth the work in advance to be prepared!

Best of Luck!
