The idea of this course is to give you a clear understanding of some key System Design concepts and a framework that helps you structure your interview and nail it.

You should go through this course in three scenarios:

  1. If you have a System Design interview coming up and want a quick crash course

  2. If you are designing a new system at work, and want to make sure you get it right

  3. If you want to know how some FAANGs and other companies have built their systems

As part of this course, we'll go through some of the conceptual things, some do's and don'ts, and most importantly we'll be looking at some of the biggest systems out there and how you could design those. There is a good probability that your next interview has one of these questions either exactly, or with some small variation.

Instructor Profile:

The Instructor of this course, currently works at Facebook and has in the past worked with some of the biggest companies in the world, and has himself designed some of the biggest systems out there. Also with his experience of taking and giving more than 500 System Design Interviews,  he knows exactly how to crack a System Design interview. If you are planning to interview in near future, this course is a goldmine of information to help to succeed.

This course aims to prepare you for system design interviews, as well as discusses how you could apply this knowledge in your day to day job.

In real world, most of the engineers don't get to design new systems often. Some don't get to design them at all. In many companies architecture is something only a few individuals do regularly. But when it comes to interviewing, we suddenly expect everyone to be master in system design. This course tries to cover some of the basic topics, as well as provide you with my approach to some of the most common system design interview questions.

Second purpose of this course is to provide senior engineers with an alternative view to system design. What I see in the industry is that we don't discuss design among ourselves much. It becomes a sensitive topic, because no real world design is perfect. And that's something I hope to change.

There are two ways I suggest to consume the course. If you have plenty of time, just watch it start to finish. I tried to construct it in a logical order, so you will accumulate more and more confidence as you go.

Alternatively, if you are short on time, or if you aren't preparing actively for interviews at the moment, you can start with the design videos, and if you aren't familiar with one of the topics I discuss, there should be either a video for that or a link to a relevant article.

The goal of system design interview is usually to cover multiple topics. It evaluates the breath of knowledge first, depth of knowledge second. For that reason, I tried to keep the theoretical part on each topic rather brief. That is - it's as deep as I expect as an interviewer from my candidates.

Finally, I will repeat myself and say that no design is perfect. There are always tradeoffs, there are always compromises that you must make. And each design is personal. It depends on what are your areas of expertise. When you watch my videos, please don't treat them as the ultimate way I would design a system, but more as a collection of ideas of how to approach the topic.

If there are more system design interview questions you'd like me to solve or additional topics you'd like me to cover, let me know!

System Design or High level system design -

Almost all the companies ask for the design of various systems in their System design interviews. Mainly the system design round is for experienced people but top companies like Google, Facebook, Microsoft, Amazon, etc are keen on asking the designs to even freshers. There is a dedicated one to two hours round for system design. The system design round has multiple purposes, the interviewer want to know your breadth of knowledge, they want to understand how do you approach an open ended problem and how do you handle stressful situations.

System Design is also known as High Level Design. High level design is nothing but deciding on what components we will be needing in our system, how all the components will communicate with each other as well as external systems and what we be the capacity of our system. These are important things while designing any system to make it reliable, available, consistent and efficient.

This course is designed in an incremental fashion, for the purpose of understanding. Initially, all the concepts and components of system design are discussed. A full proof step by step procedure is explained to tackle any system design problem. All the case studies are given in comprehensive manner and are designed by following these steps.

Low level design - Object oriented design

A detailed explanation of SOLID principles for you to become a better programmer. Learn to write quality code using

S - Single responsibility Principle

O - Open-closed Principle

L - Liskov's Substitution Principle

I - Interface Segregation Principle

D - Dependency Inversion Principle

and level up your Object oriented interviews.

Following are the promised outputs of this course:

1. You will get confidence about High Level System Design.

2. You will be able to solve any system design problem with the given procedure.

3. You will know the how to approach any problem in front of you before jumping into the design.

4. You will get better understanding of all the components of system design.

5. You will be able to participate and give your opinions in system design related discussions.

6. Your breadth of knowledge will be enlarged.

7. You can brag in front of your peers and share your knowledge.

Low Level System Design [An interview perspective]

Software Engineering interviews focus on the coding and software designing skills in an interview. These are fondly known as Algorithm and Design rounds respectively. The Algorithms round check the raw coding skills of a candidate, by the application of Data Structures and Algorithms mostly practiced in school, while the Design round tests the System design skills, which can be High Level Design [HLD] or Low Level Design [LLD].

Low Level Design is also known as Object Oriented Design [OOD] or Object Oriented Analysis and Design [OOAD]. From interns to Senior Software Engineers, top companies dedicate at least one round in the entire interview process for system design. For candidates having less than 3 years' of experience, Low Level Design plays the most crucial role because these candidates are inexperienced, hence not supposed to have knowledge of High Level Design. Candidates having experience of more than 3 years usually face the system design interviews with a mix of both HLD and LLD.

This course Low Level System Design focuses on the low level aspects of the design. The only way to get better at interviews is by practicing lots of similar problems. In this course, based upon my research, a list of most frequently asked questions in interviews is compiled. Not only is this useful for the interviews, but also for general problem solving and application design.

Every problem is broken down and discussed in a comprehensive manner:

  1. Making the problem statement clear of any ambiguity. Terminologies related to the problem are explained and expectations well laid out.

  2. Class Diagram construction serves as a road map for coding the problem

  3. The coding is done in the most elegant manner such that the users learn to approach the problem top-down. This is important because even if the class diagram is in place, it's imperative to know the sequence of class construction in program, for a smooth experience.

  4. Wherever applicable, the code is optimized further. Trade offs related to optimization are also discussed.

  5. At last, test case construction is shown to make the candidate wary about writing good test cases, and their impact on the application.

All this is done while following industry best practices. Proper time utilization during the interview is also talked about intermittently, and ways to deal with a situation when the candidate is stuck at a problem for a long time. The coding is done in C++ but the code is language agnostic to a great extent.

The course also sports Closed Captions [English Subtitles] for all the videos. They are hand-crafted, not auto-generated. This feature is helpful when the student is having problem with the accent, there's a lot of background noise present, or when you want to make detailed notes from the explanation.

After taking this course, you

  1. Will be in a better place to face LLD interviews.

  2. Can participate in design discussions related to such problems

  3. Write better code than before

  4. Have a proper theater to break the problem into pieces and deal with them independently

Guaranteed Takeaway

  • If you understand all the problems presented in this course, there won't be any fear of solving LLD questions. You'll be asking the right questions about the problem, and will be confident to jab at any design.
