Amazon Interview Experience for SDE-1(Off-Campus) 2022
Coding Interview Problem
Introduction
The Amazon SDE-1 (Off-Campus) 2022 experience is a great opportunity for students to gain hands-on experience in the workplace.
However, it can be difficult for students who are not familiar with the campus and its surroundings to get there. Thus, this guide will help you prepare for your trip and make sure that you arrive on time!
In this guide, I will be sharing my personal Amazon interview experience so that you will be able to gain knowledge and understanding through first-person experience! Here are some of the basic tips for your Amazon SDE-1(Off Campus).
So, get ready for your trip!
- Try to get there at around 10 A.M. Arrive at the campus early to put an amazing first impression by showing that you are punctual.
- Take pictures of all the stations that you visit during the day. It will give you an overview of the space that you will work in. Seeing your workspace will motivate you to perform better and experience an amazing Amazon interview experience in order to get your desired job and position.
Online Assessment Round
The Online Assessment Round is a multiple-choice test. It will be a 60-minute long test, and I had to complete it within 30 minutes, and then I could start the next step of Interviewing with Amazon.
The first part of this round consists of technical questions that cover different aspects of your professional experience and knowledge. I was asked questions such as:
- What are some patterns in software development? How do they differ from one language to another or from one operating system to another? Why do we use them?
- Describe how to write code that can handle multiple concurrent requests on a single thread (e.g., using locks)
Technical Interview Round 1
The technical interview round is the next step in the process. This is a coding test to assess your programming skills. I was asked to write code in Python, C++ and Java, with syntax errors being marked as red flags. If you have already written some programs before the interview, it will help you clear this round smoothly. But if you are completely new to programming, then try to use an existing library or source code available online (you can even take a look at our GitHub repo).
I had the same Microsoft interview experience when I applied for a junior developer job a few years ago.
I was asked to solve some coding problems on a whiteboard, and my interviewer gave me the problem, which was presented as follows:
“Let’s say that you have an array of numbers (1..10). You have to sort them by increasing their value.”
I was given a few minutes to solve the problem on my own. The interviewer gave me hints because he felt like I needed them. But they may also call time if they feel that you are not making progress.
The interviewer also asked me to write the solution on a whiteboard. They also asked me to explain how it works. You should be prepared for this part of the interview, as well.
Technical Interview Round 2
The second round of technical interviews was a two-hour long session where I was asked to solve a set of questions related to my field and also about myself. I was given 20 minutes for each question, with ten questions in total. This is where they asked questions related to algorithms and data structures like sorting, grouping etc.
The aim is to see if you can understand the problem and come up with an efficient solution for it. You do not have to be an expert in this domain but try your best. I will put up some basic questions here as well, which you can refer to. The first question is usually an introduction about your area, followed by one or two simple coding problems and then lastly, a situational problem that requires analytical skills and time management.
The interview team consists of senior members from Google’s different departments, such as Engineering or Human Resources, who are experts in their fields and can give advice on how best to approach an interview situation like this, so there is no need for panic when it comes down time!
The questions are designed to test your technical skills and analytical ability, but they are also a way for Google to get to know you better. Interviewers want to see how you think through problems and communicate with them. So, remember– be yourself!
Hiring Manager Interview
The hiring manager will ask you questions about your background and experience. They want to know how you got into the programming field, what experiences have helped shape who you are as a programmer today and how those experiences relate to working at Amazon. You should be prepared to answer these questions in depth as they can help them see if there is a fit between their organization and yours.
There are chances that your hiring manager will also ask questions about your resume (which includes past projects) and coding problems or any other relevant information. This process during the Amazon interview experience helps them understand more about who you are as an individual before making any decisions based on this first round of communication.
You’ve probably heard that the key to a successful interview is preparation. Near the top of your preparation to-do list should be preparing a list of questions for your hiring manager.
Almost always, hiring managers give the candidate time to ask questions at the conclusion of an interview.
You can be prepared to pose thoughtful and pertinent questions to the hiring manager if you already have a few in mind.
The Competition was high!
One major thing that I noticed in my Amazon on-campus interview experience was that the competition is quite high! There were about 800 students who gave this paper, and about 130 were shortlisted for the TR1 round.
This round was an easy one, so I cleared it without difficulty. The main question asked of almost all of the shortlisted students was about polymorphism.
If you are a fresher and don’t know about polymorphism, it is important to understand what it means. Polymorphism is the ability of objects to behave differently in different contexts. This means that an object can be treated as multiple different types of objects depending on its context or environment.
Another question asked from me was the difference between compile-time polymorphism and runtime polymorphism.
I am listing a few more questions that are often asked in an Amazon SDE interview –
- Given a list of words, write a program to find all palindromes within it. (Like – radar, level etc.)
- Calculate the square root of a number without using the inbuilt function sqrt ().
- What is SQL injection? How does it happen? How can we prevent it
Conclusion
I would highly recommend the Amazon SDE-1 for anyone who is seeking a prominent job. The benefits of working as an Amazon SDE are numerous and can help you build your resume, network, and gain experience in a new field. If you are looking for something that is flexible enough to fit into your schedule or if you want to change your career field, then this may be perfect for you!
