How to Prepare for Amazon Software Development Engineering Interview? – GeeksforGeeks

Amazon… “Hire and Develop the Best”. One of the Big Four Tech Companies who cares a bunch about their leadership Principles when it comes to opening a door for a campaigner in the company. Amazon is a peak company according to the 2018 LinkedIn Article. If you are a person who is preparing yourself to get into this company, you might be decidedly aware of the importance of Data Structures and Algorithms for interview homework.
Amazon-Interview-Preparation There is no doubt that this one is a must-have skill to apply for the job of SDE or software engineer role in Amazon or any other big technical school company. Hiring procedures in these companies are kind of alike but we are going to share some specific detail, tips, readiness strategy, and evaluation summons of Amazon to crack the interview. Keep in mind that the difficulty level of these rounds depends on the level of SDE side you are applying and you can prefer any scheduling terminology you are comfortable with.

Important Points to Keep in Mind:

  • Amazon gives higher weight and has a standardized script for Leadership Principles throughout the interview. It has a much stronger focus on customer obsession. So go through their leadership principles carefully if you are applying there.
  • Do some background research on the company. What’s the company doing right now or what’s the market scenario or technology they are working on currently. That shows your interest in the company and this is a good way to judge a person how much a candidate is interested in the company.
  • Interviewers are trained to not react to your answers so don’t expect yes or no answers from them that if you are heading in the right direction or not. This sucks but is a very effective way of assessing a candidate so prepare yourself to see stone-cold faces.
  • Amazon conducts a Bar Raiser round during the onsite interview and in this round, they make sure that you as a candidate raise the bar for certain competencies, which means that you should be better than 50% of the people that are currently at that level.
  • Amazon’s interview questions/difficulty levels are less consistent vs. Google or Facebook.

now it ’ sulfur meter to discuss the strategy and rounds that Amazon conducts for the lease procedure. But before that keep in mind a quick tap that works in every company… Your goal is to write just the right amount of good code and communicate well. You’re not paid to write code, you’re paid to think, figure out problems, and give the solution. To crack any technical consultation all you just need is a laptop, a exploit internet connection will solve problems regularly and within a few months, you can learn the essentials. The interview routine in Amazon is kind of similar to other big technical school companies so let ’ s discus that… Sending Application: Getting a call from Amazon for an interview is not easy if you don ’ t have any referrals. Your chances to get the interview call are more if you have a joining with an employee there. If you don ’ t have we highly recommend making connections with rent managers or recruiters via LinkedIn. besides, focus on your curriculum vitae when you are applying for the job. Make it brusque, accurate because none of the recruiters has more than 15 seconds to scan a CV. Write down only those things you are comfortable with, do not fake anything because the interviewer can spot that easily during the interview… Below is the link for the guidelines of CV. Screening Interview: Shall we invite this candidate for the wide iteration ? To filter out a distribute of candidates Amazon behavior this round and this round saves a batch of time and resources for the company. So there will be 1-2 screening rounds before the onsite interview. The screening round could be telephonic or you will be asked to complete a code challenge where you need to write clean, thoroughly, and bug-free code and that should be besides optimized. This rung consists of basic to medium charge data structures and algorithm questions, you will have some on-line document to write down your code and that will be visible to your interviewer. It can have a 2-3 code interrogate. Below is the point to keep in mind for an on-line code challenge or telephonic interview .

  • The telephonic round is not designed to be very difficult, the meet of the challenge is to be delivered at the on-site interview.
  • Amazon HR’s are pretty flexible with the phone interview so generally, you can postpone the phone interview by a week to prepare yourself.
  • Don’t bother much about Dynamic Programming or Leetcode hard questions for telephonic interviews.
  • Concentrate more on Binary Trees and Binary Search Trees. Learn how to traverse the binary tree in a different order, how to apply BFS and DFS to binary trees. You should know how to construct the tree from a given array. These questions will help to provide you with the basic foundation for any binary tree problems.
  • Check Arrays and Stacks-related questions on Leetcode and GeeksforGeeks. Also, take a glance at the Linked List-related questions on Leetcode and GeeksforGeeks.
  • For phone screens, concentrate on data structures and algorithms for about 70% and LP’s (Leadership Principles) 30%.
  • Their typical response times are anywhere between 1 day to a week. Within a week they should definitely get back with the results. In case someone fails to contact you then send an email after a week. Also, check the link Amazon Phone Interview for more ideas.

Onsite Interview: Once you get selected in the former rung, you will be invited for a closed circuit that will take one wax day, consisting of about four to five separate interviews and each of these interviews takes roughly an hour. All these rounds will be technical with BR turn ( All Technical + One Managerial ) at the end. The exact number of rounds depends upon how you perform in each round and the floor you are applying for. now here comes the character of DSA and CS fundamentals to check your tease and problem-solving skill. You need to prepare yourself with all your projects, internship, former experiences, and decidedly your cryptography and problem-solving skill. We are going to categorize this in the downstairs section… 1. Technical Coding Round (Including Projects):

  • The candidate is tested on whether he/she can solve real-world problems using the knowledge of data structures and algorithms. The expectation is to be able to arrive at the most optimized solution to the given problem. Your ability to convey your algorithmic knowledge along with code is a must.
  • Below is the distribution of the types of problems that were generally encountered in an Amazon interview. This data is based on the interview experiences from Glassdoor for Amazon.

Amazon-Data-Structure-Graph

  • Check the link How to Get a Job in Product Based Companies? to deal with in-depth technical coding questions, what approach, and tips you should follow during the interview.
  • Check the amazon site Software Development Topics to go through all the topics for technical rounds.
  • Ask all the clarifying questions, think about the Brute Force approach, optimize the solution, and then write down the code. This is the simple step we recommend you follow to solve the coding question.
  • You need to be comfortable with projects you have done in your past experience or during your internship. The interviewer will throw questions from there so make sure you have complete knowledge and detail about your project to explain it to the interviewer.

2. System Design Round:

  • System design questions are an open-ended conversation and this round is mostly conducted with an experienced candidate where they test your overall ability to design and scale technically based systems.
  • Check the link System Design Interview Questions, System Design Interview Preparation, and also check GeeksforGeeks
  • The interviewer usually is interested in the choice of resources like Databases, Storage, Logging; efficient algorithms of the functionalities; identifying all the data and classes that would be important to store if anything goes wrong in the system; what functionalities are exposed to the end-user and what not so that they might not screw up the whole system?; Scaling of Systems and servers involved; Use of Multithreading, messaging queues, Cache, etc.
  • Having a solid grasp on various database technologies, how they scale, and how they compare, knowledge of frameworks, and different technologies helps a lot in the system design round.
  • Amazon has a specific flavor of involving more of a web-based component in the system design round.
  • On a Glassdoor data set designing an e-commerce store or URL shortener service popped out frequently.

3. Bar Raiser Round: As we have already mentioned about the Bar raiser round in Amazon where a candidate is assessed on skills and cultural fit with amazon ’ s customer-centric and advanced principles. Bar raisers are particularly trained for this. Below is the point you need to keep in mind for this round…

  • ‘Bar raiser’ motive is to ensure the candidate is raising the bar not only for the specific team but for the whole company. Check the link Hire Like Amazon for more help.
  • Amazon cares a lot about the Leadership Principle that we have already talked about. You should have stories for each principle. Expect the interviewers to probe into these questions.
  • It’s almost a technical round but they judge your leadership skills, your decision-making power, your mistakes, your learning from your mistakes, your work and your conflicts with your team members, your initiative in the past work, your manager’s response to your work. Sometimes they give you situations and you have to answer your behavior in that situation.
  • Amazon is also a place where you have to adapt quickly to changing objectives, your responses have to demonstrate that you can handle that.

Interview Evaluation Criteria: After the interview, a meeting is held between all the interviewers to discuss, debate, and justify their individual ratings with the Hiring Manager and HR Representative. The interviewers give the solid compendious after the interview. The consequence of this meeting will be a final examination Inclined or Not-Inclined decision for the candidate.
A software engineer is expected to know how to code, know when to ask for steering, ability to articulate the think process, approach path to solving a problem, and deliver results seasonably while maintaining a willingness to learn new processes and adjust cursorily to changing roadmaps. An entry-level basic understanding of the effect concepts of cryptography is by and large all that is required and for higher-level ability to code and solve complex problems based on experience matter a bunch. Tips:

  • Make a habit to solve problems regularly especially from GeeksforGeeks, LeetCode, and HackerRank.
  • Take the hints. Interviewers are always helpful and they will give you precise useful hints if you get stuck. It is important to catch the hint as fast as possible and proceed with the solution. If you are not able to catch the hint it is a big red flag.
  • Never say that you cannot do it. Even if there is a problem that you have not solved before or seemed that you can’t solve, keep attacking the problem from different angles, the interviewer will give you hints. But if you would say that you can’t solve the problem it is a big red flag and you might end up getting rejected.
  • Interviewers have generally a mindset while taking the interview that if he/she can work along with the candidate in his/her daily to a job or not. So makes sure that you don’t speak something which can give a red flag sign during the interview.
  • Learn to “think out loud”. It’s weird but in an interview setting, the most important piece is showcasing how you’ve come to a solution or understanding why you’re doing X before Y.
  • Your interviewer wants to see 3 key things in your code. It should run fast, not take up more memory than it needs to, and is stable and easy to maintain. Accomplish that and you’re already ahead of most people.
  • For behavioral questions read about the STAR method to describe a situation where you solved an issue that relates to the question; Explain the tasks you had to complete in order to solve the issue; Describe the action you took to complete the tasks; And close with the results of your efforts.
