How To Study For AWS Interview Questions

To land the AWS jobs of your dream, there is a bunch of things you can do to enhance the chance of becoming a prospective candidate in the employers’ eyes. One of those things is to prepare thoroughly for the interview questions that could be possibly asked so that you can be as confident as a lion! How to do it? Take a look at the below!


Investigate the company

Before attending any interview, including AWS, do your homework. Interviewers can tell if you have done extensive study on the firm you want to work for, and they like it when you already know a lot about it.

If you haven’t done enough research about the firm, your rivals may be able to go ahead of you since you will fail fundamental questions such as:

  • What are your impressions of us?
  • Why did you decide to apply for this position at this company?
  • What motivated you to apply for this position?

The beginning of an interview is your chance to shine! It’s time to create a good first impression. As a result, don’t go in with no understanding of the industry because this is the quickest way to shoot yourself in the foot and fail to acquire the job! Prepare yourself by learning about the company, who they are, how they make money, who their normal clientele are, and so forth.¬†Of course, you don’t have to be an expert in their field, but you should grasp the fundamentals.

Prepare to discuss particular achievements

Many AWS job seekers fail to secure well-paying employment despite passing their AWS certification examinations because they make broad comments and utilize broad language when presenting their successes. To distinguish oneself, prepare particular data and speak about specifics. Make sure you have facts and data to back up what you did in past employment.

However, it is important to note that recruiters are more interested in HOW you accomplished your former job than in WHAT you did. Because of the scope of work of an AWS cloud practitioner, they may not be interested in how you climbed to become a team leader in your previous position, but they may be interested in how you overcame doubt, rejection, hardship, and lack of support.

As a result, don’t spend too much time bragging about your achievements. Instead, spend more time discussing how you overcame obstacles and solved issues to reach success!

Prepare yourself to deal with hardship

Be prepared for the reality that answering AWS interview questions will not be easy. You will be asked simple questions at first, but as the interview proceeds, be prepared to answer technical questions about the position for which you have applied.

When things get bad, only the tough get going, as the saying goes. When faced with a difficult question, don’t hide your head in the sand. Play out how you handled difficult situations in your previous experience. As you can see, there is no uniform response to these sorts of queries. There is no reason why you shouldn’t impress the interviewers if you can use how you addressed challenges in the past! Remember that interviewers are humans just like you, and they confront obstacles on a daily basis. You are unquestionably the ideal candidate if you can demonstrate your ability to address common challenges.

Keep in mind that interviewers are taking notes on everything. Don’t speak too quickly!


AWS interviews are data-driven interviews. Interviewers must record what you say. The information gathered will subsequently be evaluated. As a result, before preparing for the interview, ensure that you understand the important themes that you will discuss. During the interview, keep your cool and answer all questions accurately and concisely. Don’t get sidetracked when you see them typing as you respond. Don’t be esoteric, and speak at a rate they can document.

Don’t skip over important questions

One thing you should keep in mind as you prepare for the AWS interview is that you should not skip any questions. If you do, you will be unable to return to them afterward. If you do, the interviewers will believe you are attempting to make things up or avoid replying, which may not be the case. When asked a basic question, make an attempt to provide the best response possible, even if you are unsure. It is preferable to die trying than not trying at all!

Be truthful and tell them if you don’t know

You should not, as you have just learned, skip questions. But keep in mind that we were addressing fundamental issues. If you are asked about non-core topics that you are unfamiliar with, don’t waste time answering them. Tell them you’re not sure. It is preferable to be open than to appear to be making things up.

Get as specific as possible

The majority of questions are open-ended. Be as thorough as possible in order to stand out from the throng. If you don’t understand something in the questions, ask clarification questions. Even if the question appears to be a definition of something like “What is AWS and how does it work?” or hypothesis one like “Which certification will you get next on AWS Cloud Certification Path and why?” place your response in context wherever possible. This will provide you with data points that may boost your chances of landing the job!

Demonstrate your ability to express technical topics clearly

Employees who can successfully express technical concepts are highly valued by employers. Communication is a crucial talent, and even if you’re a technical wizard, if you can’t communicate well with others, especially those without such a strong technical background, you’ll be at a significant disadvantage. Many AWS interview questions will need you to describe a technical idea, which you should do as simply and effectively as possible. You will come across more clearly if you imagine you are conveying the subject to someone with significantly less understanding than you.

Use AWS Cloud Practice Tests

There are several AWS Cloud Practitioner practice exams available online that can help you prepare for your AWS interview. These tests will give you an idea of the types of questions you can expect and help you identify areas where you may need additional study.
