Depth Of System Design Interview Question
The course did a reasonable job of going deep into the architecture of each problem. Although it would be sufficient for most engineers, some senior engineers might feel that they need more details. For SDIs, one crucial thing is to know the tradeoffs between different design decisions. For example, you need to know, which data partitioning scheme best fits your system, or at which layer you can introduce a cache to speed things up. Discussing these options during the interview is the most important aspect interviewers are looking for in a candidate. Grokking the System Design did an excellent job in discussing the tradeoffs between different designs.

Hello guys, If you are looking for a System design Primer for Tech interviews then Grokking the System Design Interview Course on Educative by Design Guru is a great resource.
When I first started preparing for System design interviews there were not many resources available, I search in Udemy for System design course only to find outdated, half-baked course, YouTube has some video’s but there is no resource which can provide a well structured preparation required for interviews.
At that time I come across Grokking the System Design Interview Course on Educative by Design Guru and immediately fell in love with it. The course was well structured, detailed, and discussed popular System design questions with in-depth analysis and their use of diagram was amazing. Educatives interactive learning platform was another cherry on cake.
Since then situation has changed a lot, there are now many dedicated System design platforms and websites like , Exponent, which even provide mock interviews for FAANG companies and even Udemy has got amazing System design courses like Mastering the System Design Interview by Frank Kane and even Educative got two sequels of System design interview but it sill remain one of my favorite resource.
If you are thinking to join this course but not sure, then read on, I have shared my thoughts and reviewed the course on its merit of what it offers for the price it charged and time it takes.
So whats the wait? Lets start!
Grokking The Coding Interview: Pros And Cons
There are good reasons why we cant afford to skip the pros and cons of the platform we are reviewing.
One reason is to isolate the key takeaways of the review quickly.
Another and more important reason is that no software is perfect. We must ensure that any software or platform that scales through our decision-making process is ticking enough of the right boxes.
I think the pros should be considered first.

What I Liked About This System Design Course
One of the best things about this course is that mentors from FAANG and other top-tier MNCs give instruction for the course. The mentors educate and advise you based on their own personal experiences. They utilize their real-life experience in their firms as a reference to prioritize the types of questions to familiarize you with.
The mentors assist you with all aspects of the interview process by providing placement support. This ensures that the student receives clear instructions and a plan for approaching the job application process. 1:1 mock interviews, profile optimization, and profile development are all examples of this placement help.
Theres also the Flexible Pass option, which is helpful if youre a working professional who wants to learn while still working. It does this by giving you access to classes from various batches as well as the LMS portal, where you may watch recorded lectures at your leisure.
All of the lessons are live interactive sessions in which you can communicate with the mentors in real-time, and there are also one-on-one doubt clearing sessions to clear out any remaining doubts. If you are unable to continue with the lessons, you will be eligible for a full refund if you notify us within the first two weeks of the courses start date.
When you visit the website, an expert reviews your profile and then connects you with a mentor who will take you to the course that best meets your needs.

Requirements And Goals Of The System
You should always clarify requirements at the beginning of the interview. Be sure to askquestions to find the exact scope of the system that the interviewer has in mind.
Our URL shortening system should meet the following requirements:

Basic System Design And Algorithm
The biggest question for our service is how to generate a short and unique key when given an URL. The approach we will be looking at today is by encoding the actual URL.
We can compute a unique hash of the given URL. The hash can then be encoded for display. This encoding could be base36 or base62 . If we add + and /, we can use Base64 encoding. A reasonable question would be, what should be the length of the short key? 6, 8, or 10 characters?
Using base64 encoding, a 6 letter long key would result in 64^6 = ~68.7 billion possible strings.
Using base64 encoding, an 8 letters long key would result in 64^8 = ~281 trillion possible strings
With 68.7B unique strings, letÃ¢s assume six letter keys would suffice for our system.
If we use the MD5 algorithm as our hash function, it will produce a 128-bit hash value. After base64 encoding, weÃ¢ll get a string having more than 21 characters . Now we only have space for 8 characters per short key, how will we choose our key then?
We can take the first 6 letters for the key. This could result in key duplication, to resolve that, we can choose some other characters out of the encoding string or swap some characters.
There are some potential obstacles when taking this approach:
If multiple users enter the same URL, they will get the same short link.
Parts of the URL can be URL-encoded.
A Few Years Ago A New Online Learning Platform Named Educativeio Wanted To Know If Id Like To Produce A Course For Them
Although I kindly declined , I was intrigued by the platform.
Well, for one, the course selection on Educative.io is not only robust but wonderfully specific.
For example, Reintroducing React: V16 and Beyond was created for web developers who dabbled in React a year or two ago, but need a modern refresher.
Ruby Concurrency for Senior Engineering Interviews? You dont get more specific than that.
Similarly, theGrokking the System Design Interview course on Educative.io is designed for those who need brushing up on a highly specific skill set: the system design process.
And it was created by hiring managers at Google, Facebook, Microsoft, and Amazon.
That means this course contains actual Google system design interview questions, for example.
So if youre hoping to land a job at one of the FAANGs , read on.

Is Grokking The System Design Interview Worth It
This course is developed by hiring managers working at top tech companies such as Google, Facebook, Apple, and Microsoft. They have a list of various design problem standards for a different interview with detailed expatiation on all tech and terminologies used in System design interviews.
These questions are repeatedly asked in many interviews, instructor has designed and explained the problem at a basic level till all tech and options are available to design a scalable system and tackle questions that are asked during the flow.
Every example is structured perfectly to cover all requirements and the design of a complete system. Fair assumptions, calculations, and technology have been used to make system more optimal and scalable that is crucial for any SDI interview.
S How I Approach The System Design Questions In Interviews
These are the steps I go through mentally in the interviews, followed by actual interview experiences:
- a) Be absolutely sure you understand the problem being asked, clarify on the onset rather than assuming anything
- b) Use-cases. This is critical, you MUST know what is the system going to be used for, what is the scale it is going to be used for. Also, constraints like requests per second, requests types, data written per second, data read per second.
- c) Solve the problem for a very small set, say, 100 users. This will broadly help you figure out the data structures, components, abstract design of the overall model.
- d) Write down the various components figured out so far and how will they interact with each other.
- e) As a rule of thumb remember at least these :
- processing and servers
It generally depends what you are and you will be working on. Also what your level is but these are some of the more frequent interview questions.
- Design amazon’s frequently viewed product page
- Design an online poker game for multiplayer. Solve for persistence, concurrency, scale. Draw the ER diagram for this
- Search engine : basic crawling, collection, hashing etc. Depends on your expertise on this topic
- Design a picture sharing website. How will you store thumbnails, photos? Usage of CDNS? caching at various layers etc.
- Design a news feed : news feed

If you consider top-tech giants such as Amazon, Google, Uber, Twitter, Apple, and Facebook, they ask multiple system design live problems to candidates during their interview process.
So, I am providing you with a review of one of the most popular and effective courses on System design.
Questions based on standard design have become a crucial part of a system design interview.
However, most engineers struggle with or during system design interviews because of the unstructured nature of these interviews and lack of experience in developing large-scale systems.
What Does Grokking The System Design Cover And How Well
This is one of the best System Design courses in the market. It is a text-based and interactive course. It provides a step-by-step approach to mastering System Design Interviews.
They have carefully selected a collection of questions that have been regularly asked by top organizations, and they also provide extensive experience in dealing with any system design challenge.
The course also follows a pre-determined framework for each design challenge, which includes thinking about the big picture, security, API design, database architecture, expected demand, capacity estimation, and then delving into the subtleties particular to each situation. This pattern may be seen throughout the course since it is applied to each question.
At Big tech companies like FAANG engineering interviews, system design rounds have been a common occurrence. When Facebooks stock began to rise, and everyone in Silicon Valley wanted to work there, there were no resources available to prepare for the design round.
The interview bible at the time was ex-Googler Gayle McDowell’s Cracking the Coding Interview book but it didnt cover any software design topics. The Grokking System Design Interview course immediately filled this need.
