How should one approach System Design questions during an interview?

Here's the step by step guide:

🧵👇🏻

System design interviews are generally open ended discussions. There's no one right answer.

The main focus in this round is to see your thought process and whether you'll be able to design a minimal system keeping future scale in mind and by following the standard principles.

Know that many interviewers deliberately make it hard to see how you approach a given problem.

You cannot possibly design a complex system in 1-2 hours which engineers usually take months to years to design, develop and build.

So this is how you should approach this round:

1. Clarify the requirements: As mentioned earlier the questions are generally very open ended. So you need to ask a lot of question to set the scope clear for the discussion.

Example: "Design an application like Twitter"

Twitter has a lot of features like:
- Post tweet
- Home timeline
- Profile timeline
- Analytics
- Likes
- Retweets
- Following
- Bookmark
- Trending etc

You get the idea!

Are you a Senior Developer & struggling to switch your job?

Here's a thread on how you should prepare before sending out job applications:

🧵👇🏻

First of all know that there's a lot of demand for good software developers.

It's hard for companies to hire good mid level developers. Some of the interviewers I've talked to recently have mentioned this!

So, if you're good, you can always get into a high paying job.

I have 6.5 years of experience mainly as a Backend Developer. Although I do work a bit of front-end tasks as well as part of my current job.

In this thread I'm going to talk about how I would prepare if I was going to apply for a job interview.

As a mid level developer having 4 - 8 years of experience, you will be expected to have certain skills to be hired by companies. Skills like:

- Problem Solving
- HLD
- LLD
- Mentoring / Code reviews
- Taking responsibility
- Leading end-end development & release of projects etc

Problem Solving:

Even though we mostly never write a lot of game changing Algorithms and use data structures, you're still expected to know the most common ones and how to use them to solve problems:

- Tree
- Linked List
- Heap
- Hash Map
- Array etc

Most commonly used AWS services:

🧵👇🏻

1. Elastic Compute Cloud (EC2):

EC2 instances are basically servers with an operating system which can be used to run your applications on the internet just like you run your applications on your laptop during development.

2. Relational Database Service (RDS):

RDS is a distributed relational database service.

Amazon RDS is available on several database instance types - optimised for memory, performance or I/O - and provides six familiar database engines to choose from, including:

- Amazon Aurora
- PostgreSQL
- MySQL
- MariaDB
- Oracle Database
- SQL Server

3. Elastic Container Service (ECS):

AWS ECS is a fully managed container orchestration service.

ECS has been a foundational pillar for key Amazon services and it can natively integrate with other services such as Amazon Route 53, Secrets Manager, AWS Identity and
