When I sat down for my Amazon interview, I thought -

First round hai kya hi puch lenge 💁‍♂️😁

They asked 𝐓𝐑𝐈𝐄 + 𝐁𝐚𝐜𝐤𝐭𝐫𝐚𝐜𝐤𝐢𝐧𝐠 + 𝐌𝐞𝐦𝐨𝐢𝐳𝐚𝐭𝐢𝐨𝐧 Que 😑😣

Socha kuch or 𝐒𝐡𝐞𝐞𝐭𝐚𝐥, nikla kuch or 😥

Prepare well and don't assume they will ask easy questions.

REST APIs: The foundation of modern web development

As a software engineer, I have always been passionate about sharing my knowledge and helping others to understand complex technical concepts. That's why I was so excited to create this small presentation on REST API.

For those who may not know, a REST API (which stands for Representational State Transfer API) is a way for different software systems to communicate with each other through the internet.

It's a crucial component of modern software development, and something that every aspiring developer should understand.

Imagine you're trying to book a flight online. When you search for flights and enter your preferences, the website sends a request to the airline's computer system to find available flights that match your criteria. The airline's system then sends a response back to the website with the available flights, and you can choose one to book. This interaction between the website and the airline's system is made possible through a REST API.

There are five main methods used in a REST API:

GET - retrieves a specific resource or collection of resources
POST - creates a new resource
PUT - updates an existing resource
DELETE - removes a specific resource
PATCH - partially updates an existing resource

The response from a REST API can either be a success or an error. A success response typically includes the requested information or a message confirming that the requested action was completed. An error response includes a message explaining why the request could not be completed.

Overall, a REST API is a crucial tool for allowing different software systems to communicate with each other and exchange information seamlessly.

If you're working with software systems or just want to understand how different websites and apps work together, it's important to understand the basics of REST APIs.

I know firsthand how confusing and overwhelming it can be to learn about new technologies, especially when you're just starting out in the field. That's why I wanted to create this presentation - to provide a clear, concise, and easy-to-understand explanation of what a REST API is and how it works.

I hope that this presentation will be helpful to those who are new to software development, or who are simply looking to learn more about APIs. And I plan to keep creating more such documents in the future, so that all the needy and new enthusiasts out there can benefit from my knowledge and experience.

So if you're interested in learning more about APIs, or if you have any questions or feedback about this presentation, please don't hesitate to reach out. I'm always happy to help, and I'm committed to doing my part to make the world of software development more accessible and understandable to everyone.

Stay ahead of the curve in 2023 by learning GraphQL: the modern, flexible alternative to REST APIs.

As we gear up for another new year, I wanted to share some thoughts on a topic that I think will be crucial for developers in 2023: GraphQL.

If you're not already familiar with GraphQL, it's a query language for your API that allows clients to request exactly the data they need, and nothing more. This means that you can get all the data you need in a single request, rather than having to make multiple API calls to get all the data you need.

But why is this important? Well, for one thing, GraphQL can help improve the performance of your applications. With REST APIs, you often have to make multiple API calls to get all the data you need, which can be slow and resource-intensive.

With GraphQL, you can get all the data you need in a single request, which can greatly improve the performance of your application.

Another reason to learn GraphQL is that it can help improve the flexibility of your API. With REST APIs, you often have to design your API around the needs of your clients. This can be a problem if your clients have very different data needs, as you may have to design multiple endpoints to accommodate them all.

With GraphQL, clients can request exactly the data they need, which makes it much easier to design a flexible API that can accommodate a wide range of client needs.

So if you're a developer looking to stay on top of the latest trends in the field, learning GraphQL is definitely worth considering in 2023.

And if you're not familiar with the difference between REST APIs and GraphQL, the attached illustration should help demystify things for you.

Wishing you a very successful year ahead!

I hope this helps! Let me know if you have any questions or need further clarification.

Amazon || 𝐑𝐞𝐜𝐫𝐮𝐢𝐭𝐦𝐞𝐧𝐭 𝐏𝐫𝐨𝐜𝐞𝐬𝐬 𝐅𝐨𝐫 𝐒𝐃𝐄 1🤩 
 
𝑴𝒖𝒔𝒕 𝑺𝒂𝒗𝒆 𝒂𝒏𝒅 𝑺𝒉𝒂𝒓𝒆 !!!!
 
 
It's every engineer's dream to get into top product-based companies, some of us called them FAANG or MAANG. Here I am sharing the journey you will go through the interview process from Amazon.


𝐂𝐓𝐂 𝐁𝐫𝐞𝐚𝐤𝐝𝐨𝐰𝐧 (Source : Internet) :

Base Salary : 19LPA
Bonus : 6.5 LPA(Y1) + 5 LPA (Y2)
RSU : 15.5 LPA
Total Compensation : 46 LPA 🤩

 
 
𝐑𝐞𝐜𝐫𝐮𝐢𝐭𝐦𝐞𝐧𝐭 𝐏𝐫𝐨𝐜𝐞𝐬𝐬:
Amazon conducts 4 rounds to select freshers as SDE (SDE-1) in their organization off campus. The following rounds are conducted:
- Online Coding Round
- 2 Technical Rounds
- Bar Raiser round


 
𝐎𝐧𝐥𝐢𝐧𝐞 𝐂𝐨𝐝𝐢𝐧𝐠 𝐑𝐨𝐮𝐧𝐝:
This round is hosted online and the candidates are presented with 2 coding questions, the questions are of intermediate difficulty, mainly from Arrays, strings, and matrices.
To clear this round, one should have a strong understanding of these data structures.
Time given is 70 minutes. 
 
 

𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐑𝐨𝐮𝐧𝐝 1:
Technical rounds are face-to-face algorithmic rounds in which candidates are presented with 2-4 questions, all from data structures. The most commonly asked DSs are the matrix, binary tree, BST, and Linked list.
 
 
 
𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐑𝐨𝐮𝐧𝐝 2:
The same as the previous round, however, the difficulty is increased and more questions from Trees, BST, and Tries are asked. One should have a clear knowledge of tree-based recursion, and the standard questions based on it are a must. 
 

 
𝐁𝐚𝐫 𝐑𝐚𝐢𝐬𝐞𝐫 𝐑𝐨𝐮𝐧𝐝:
Amazon has 16 leadership principles and questions are asked on those, and generally, these questions are asked in all the interview round and especially in Bar raiser round along with 1-2 DSA problems.



𝐈𝐦𝐩𝐨𝐫𝐭𝐚𝐧𝐭 𝐏𝐨𝐢𝐧𝐭𝐬 𝐭𝐨 𝐫𝐞𝐦𝐞𝐦𝐛𝐞𝐫 :
 
- Never postpone your interview(That might lead to many gaps in dates because multiple candidates are giving interviews.)
 
- Take the Bar Raiser round seriously(Always prepare for leadership principle questions, It is the most important round of the process.)
 
 - Always focus on concepts(Never mug up the questions, always try to understand the questions.)
 
- Be confident about your answers(Never doubt yourself in the interview.)
 
- Always try explaining your approach before coding(It would be a better practice if you give a brute force approach.)
 
- Have a good understanding of time complexity(I was also asked TC of every question.)

Happy Learning !!

Instead of learning solutions of LeetCode questions, understand patterns! 🙂

𝑴𝒖𝒔𝒕 𝑺𝒂𝒗𝒆 𝒂𝒏𝒅 𝑺𝒉𝒂𝒓𝒆 !!!!

For ex.

If input array is sorted then
- Binary search
- Two pointers

If asked for all permutations/subsets then
- Backtracking

If given a tree then
- DFS
- BFS

If given a graph then
- DFS
- BFS

If given a linked list then
- Two pointers

If recursion is banned then
- Stack

If must solve in-place then
- Swap corresponding values
- Store one or more different values in the same pointer

If asked for maximum/minimum subarray/subset/options then
- Dynamic programming

If asked for top/least K items then
- Heap

If asked for common strings then

- Trie

Else
- Map/Set for O(1) time & O(n) space
