A Note About Video Resources

He cracked FAANG interviews in 10 companies including Amazon, Facebook, UBER, Microsoft

Some videos are available only by enrolling in a Coursera or EdX class. These are called MOOCs.Sometimes the classes are not in session so you have to wait a couple of months, so you have no access.

It would be great to replace the online course resources with free and always-available public sources,such as YouTube videos , so that you people can study these anytime,not just when a specific online course is in session.

Learn About Amazon’s Culture

Most candidates fail to do this. But before investing tens of hours preparing for an interview at Amazon, you should take some time to make sure it’s actually the right company for you.

Amazon is prestigious and it’s tempting to assume that you should apply, without considering things more carefully. But, it’s important to remember that the prestige of a job won’t make you happy in your day-to-day work. It’s the type of work and the people you work with that will.

If you know engineers who work at Amazon or used to work there, talk to them to understand what the culture is like. The leadership principles we discussed above can give you a sense of what to expect, but there’s no replacement for a conversation with an insider. Finally, we would also recommend reading the following resources:

    • Calculate time complexity
    • Discuss how you can optimize your solution

To practice coding questions, we recommend using our articles, 73 data structure questions and 71 algorithms questions, which have links to high quality answers to each problem. They are organized by type of data structure or algorithm as well as by difficulty level. Don’t forget to practice on a whiteboard or Google Doc instead of in an editor.

3.2.2 System design interview preparation

For system design interviews, we recommend getting used to the step-by-step approach hinted at by Amazon in the video below.

Here is a summary of the approach:

3.2.3 Behavioral interview preparation

What Exactly Is Amazon Looking For

At the end of each interview your interviewer will grade your performance using a standardized feedback form that summarizes the attributes Amazon looks for in a candidate. That form is constantly evolving, but we have listed some of its main components below.

A) Notes

The interviewer will file the notes they took during the interview. This usually includes: the questions they asked, a summary of your answers and any additional impressions they had .

B) Technical competencies

Your interviewer will then grade you on technical competencies. They will be trying to determine whether you are “raising the bar” or not for each competency they have tested. In other words, you’ll need to convince them that you are at least as good as or better than the average current Amazon SDE at the level you’re applying for .

The exact technical competencies you’ll be evaluated against vary by role. But here are some common ones for SDE roles:

  • Problem solving
  • Have Backbone Disagree and Commit
  • Etc.

D) Overall recommendation

Finally, each interviewer will file an overall recommendation into the system. The different options are along the lines of: “Strong hire”, “Hire”, “No hire”, “Strong no hire”.

    Cracking the top Amazon coding interview questions

    There is more than one way of approaching each of the technical questions , be prepared with every possible approach. Also here I have used C++ as the language you can use any language of your convenience. Now lets look at some of the sample questions thats frequently asked in the Technical round of Amazon Interview.

    Q1. Write an efficient program for printing k largest elements in an array. Elements in array can be in any order.

    For example, if given array is and you are asked for the largest 3 elements i.e., k = 3 then your program should print 50, 30 and 23.

    There are many methods to approach this problem.

    Method 1

    1) Sort the elements in descending order in O) 2) Print the first k numbers of the sorted array O.

    < /pre> #include < bits/stdc++.h> using namespace std void kLargestint main int n = sizeof / sizeof int k = 3 kLargest }< pre> 

    Q2. What are class and object in C++? A class is a user-defined data type that has data members and member functions. Data members are the data variables and member functions are the functions that are used to perform operations on these variables. An object is an instance of a class. Since a class is a user-defined data type so an object can also be called a variable of that data type.

    class A} 

    Q3. Given an array of integers, write a function that returns true if there is a triplet that satisfies a2 + b2 = c2.

    Q4. What is operator overloading?

    Now this could be asked both in C++ and in Java.

    Amazons Focus On Scalability

    As you might expect from the tech behemoth, Amazon is very concerned with how things scale. Being able to not only solve certain technical challenges but also scale them is an important criterion on which you will be assessed.

    For system design-based questions specifically, having a solid grasp of the various database technologies, how they scale, and how they compare will be a feather in your cap when confronted with how to increase the scale of your initial solution for a problem.

    Knowing how SQL compares to NOSQL, and being aware of the differences between DBMS and RDBMS, etc. is good to know. It is worth taking the time to do your homework on how these technologies compare.

    Expect to be able to effectively navigate system design-style interviews. These interviews tend to test your overall ability to design and scale technically based systems.

    If youre unfamiliar with this style of interview or if you want practical tactics to prepare for system design interviews, check out this post by Byte by Byte that covers how to ace your interview.

    Ill not only share tips for the interview but also how to land the interview!

    So, lets begin!

    Screening Call With Hr Or Internal Recruiter

    This lasts about 45 minutes to 1 hour. HR or the recruiter will spend most of the time asking questions about your career. They will usually start in chronological order from your ï¬rst job to your most recent position. Youâre expected to answer questions in the

    Itâs unlikely youâll get too much feedback during that conversation, and it might seem more âinformationalâ or casual â but it hardly ever is. Job-seekers tend to come out of the conversation feeling good, which is strange because you have no indication of whether or not you made it to the next round! I believe the reason for this is because the recruiter/HR will let people talk most of the time without interrupting them. People love to talk but donât realize whether or not theyâre saying the right things. Hereâs the best way to approach this initial call and to make sure you are saying right things: 1) Practice talking about your career from start to ï¬nish. There will inevitably be pieces youâve forgotten, including the reasons youâve left certain jobs and so forth.
