Behavioral/ soft skill interview questions

Amazon requires behaviors that conform to the 14 Principles of Leadership (LP).

So, in the behavioral interview round, each question will be a “test” of at least one LP.

Your answer, i.e. the story, should be in STAR format. It is the situation, task (obstacle) actions, and results. Make sure that you answer the interview questions for 4-5 minutes, and that you give measurable results. You need to explain how you know you have succeeded or failed.

In your explanation, be concise and to the point. Below are the samples of the questions.

Amazon behavioral questions:

• Tell me about a time when you delegated a project effectively.
• Tell me about a time when you coached someone.
• When have you used your fact-finding skills to solve a problem?
• Tell me a challenge you had where the best way forward was not clear cut. How did you decide what to do?
• Give me an example of something you tried to accomplish but failed.

Company-specific questions

How to tell a fake leadership question from a real one?

If you want to spot fake questions easily, you should know the major themes of Amazon Leadership principles.

A real onsite Amazon interview question will never ask you hypothetical questions, brainteasers, and anything else different from behavioral questions. Real Amazon questions are behavioral questions.

All real Amazon interview questions look like this: “Tell me about a time when you {desired action}.”

How to answer Amazon interview questions?

In your answers, Amazon wants you to demonstrate deep understanding and clear thought, using the STAR method.

• Situation: Describe the situation.
• Action: Describe the action(s) you took to handle the task.
• Results: Share the results achieved.

Through behavioral questions, the interviewer wants you to show them your past behavior, which will be an indication of future job success. Behavioral situations and answers can be very complex and may waste a lot of the interviewer’s time. The point is, you to give a lot of useful information in a short amount of time. The STAR method does exactly that. Your interviewer will learn a lot of information about you without wasting the interviewer’s time.

At the end of the interview, don’t forget to ask your interviewer some company-specific questions. Below are the samples:

• What does a typical day in this role look like?
• What are the primary responsibilities of this position?
• How do you measure the success of the person in the position?
• What qualities does Amazon require to succeed in the company?
• What sets a good worker apart from a great worker?
• Where do you see Amazon in five-ten years?

You should always have at least a couple of questions prepared for your interviewer. An interview isn’t just a time to pitch yourself to the company. The job has a significant impact on your life. You’ll be spending 40 hours a week in the company. So you’ll want to choose your workplace wisely.

An interview is a platform where both prospective employers and employees evaluate each other. Ask questions without fear of judging you for what you want to know.

Interview preparation is more than understanding the technical subjects. In fact these are two different things. Interview preparation rather means enhancing your answering skills. It is crucial to maintain good communication throughout the interview. To understand the question well and then answer. It does matter how much and what you speak in the interview.
