    How I Prepared For Amazon Interview Software Engineer

    Technology is on the rise and software engineering has been becoming more popular and competitive. Big tech companies such as Amazon are always the ideal workplace environment to chart career path for many people. I am no exception and I took my shot with Amazon and succeeded in landing an offer.

    It took me two weeks to prepare for the interview process, so I would recommend you to spend a lot of time to prepare carefully as well. I divided this preparation process into two phases, starting phase and running phase.

    Starting Phase

    During this phase, I focused mainly on reviewing the fundamentals of data structures, some of the popular algorithms and familiarizing myself with the .

    For algorithms, knowing some of the well-known ones are quite important. It could help you to solve the interview problems faster, and help you stand out as a bright and knowledgeable candidate. Again, I used GeeksforGeeks website to review algorithms

    In this phase, I also spent a day to read through and try to understand what the are, as they are the core of the Amazons culture and what contribute to Amazon success.

    Running Phase

    This is the phase that mostly focuses on preparing and practicing for interview questions, and starts solving as many coding problems as possible.

    Situation: What was the problem and why it happened.

    Task: What was the tasked that had been assigned to you to solve the problem.

    Result: The final result of your action.

    Good Versus Great Technical Candidates

    In order to make the cut when interviewing at a company like Google, Facebook, or Amazon, you have to distinguish yourself from other candidates. Giving a good answer wont be enough to get an offer. Youll need to give a great answer if you want to make an impact.

    So here are some details that make the difference between an interview that is just ok, and one that will impress your interviewer:

    A good or “just ok” technical candidate:

    • Completely answers the coding questions, but doesnt interact with the interviewer
    • Interacts with their interviewer, but struggles to take hints or change direction when prompted to do so
    • Is able to finish the coding problem, but stumbled through their behavioral questions at the start of the interview
    • Gets stuck once or twice during the interview and struggles quietly until they are able to move past it
    • Offers a complete solution that is difficult to follow
    • Comes up with a workable solution after coming to quick conclusions that they haven’t verified with the interviewer
    • Follows one approach that works, but neglects to examine its tradeoffs or other possible approaches
    • Tests the code after being prompted by the interviewer to do so
    • Finishes and tests the code by the end of the session, but does not leave time to consider space and time complexity

    A great technical candidate:

    What Happens Behind The Scenes

    Software Development

    Your recruiter is leading the process and taking you from one stage to the next. Here’s what happens at each of the stages described above:

    • After the phone screens, your recruiter decides to move you to the onsite or not, depending on how well you’ve done up to that point
    • After the onsite, each interviewer files their notes into the internal system, grades you and makes a hiring recommendation
    • The “Debrief” brings all your interviewers together and is led by the Bar Raiser, who is usually the most experienced interviewer and is also not part of the hiring team. The Bar Raiser will try to guide the group towards a hiring decision. It’s rare, but they can also veto hiring even if all other interviewers want to hire you.
    • You get an offer. If everything goes well, the recruiter will then give you an offer, usually within a week of the onsite but it can sometimes take longer

    It’s also important to note that recruiters and people who refer you have little influence on the overall process. They can help you get an interview at the beginning, but that’s about it.

    Easy Graph Interview Questions

    You might be tempted to try to read all of the possible questions and memorize the solutions, but this is not feasible. Interviewers will always try to find new questions, or ones that are not available online. Instead, you should use these questions to practice the fundamental concepts of graphs.

    As you consider each question, try to replicate the conditions youll encounter in your interview. Begin by writing your own solution without external resources in a fixed amount of time.

    If you get stuck, go ahead and look at the solutions, but then try the next one alone again. Dont get stuck in a loop of reading as many solutions as possible! Weve analysed dozens of questions and selected ones that are commonly asked and have clear and high quality answers.

    Here are some of the easiest questions you might get asked in a coding interview. These questions are often asked during the “phone screen” stage, so you should be comfortable answering them without being able to write code or use a whiteboard.

    Which Programming Language Should I Use

    Before you start preparing for the other steps of the interview process, it would be prudent to have a good idea of which programming language you will use during the interview.

    When it comes to this question, I have some pretty simple advice: embrace what you are comfortable with, and stick to what you know.

    It is fairly common to want to use multiple languages in our field. But, when preparing for an interview, it is best to stick with just one.

    This will help shift your focus from worrying about which language you will use, to thinking of problems you have solved with the language you are most comfortable with.

    Once you know which programming language you will use, you are ready to take on the challenge of the technical phone interview.
