The AWS interview process is backbreaking but consistent. This makes it easy for you to prepare for what’s to come.

It also drastically reduces the chances of you being surprised at the interview.

You must know that all this doesn’t mean the interview is in any way easy, it just gives you an inkling of what to expect.

This process can last for months sometimes.

Expect that a large number of the questions would be based on your technical skills and your experience with the AWS platform.

The Aws Hiring Process

This is a breakdown of what the AWS interview process entails.

  1. Online Assessment

The assessment comes after you have been shortlisted. The usual time given for completion is two hours.

This stage is wholly to test your skill. You would be faced with quantitative and logical reasoning, coding questions, technical questions on OS, Java, big data, data science, networking and other related topics.

  1. Screening Call

This call which lasts for about 45 minutes to an hour, would involve the interviewer asking career-related questions.

The questions are not limited to your current job alone, they would ask questions about your first job and how you’ve progressed in your career.

The focus would be on your technical skills. Use the STAR method to answer the questions asked.

This stage is usually conversational and casual.

  1. Interview with the Hiring Manager

This stage can be in person or over the phone. It usually is one of the “easy” stages of the interview because the hiring manager is going to be your manager if you get the job and they need to make a hire.

So, they are nice and welcoming. This doesn’t mean they ask easier questions, though. For this stage, arm yourself with questions about the goal the hiring manager has.

Also, you would need to talk about your career and expertise in AWS and other related systems.

  1. The final interview

This stage of the interview is for them to see how well you fit into the Amazon culture. You might have to go through 2-9 interviewers during this stage, depending on the level of position you’re being interviewed for.

Some questions would be related to your role, others wouldn’t be. Also, you would get to be interviewed by the bar raiser who is an interviewer with more experience.

The bar raiser would usually be the roughest interviewer in this stage because of their vast experience.

Be prepared for long minutes of tasking conversation with the bar raiser.

Be fully armed with all things AWS and use the STAR method to answer questions.
