V: Algorithm Data Structure And Coding
- Data structure and algorithms are important to develop a system. As each system design has its own set of algorithms and data structures, it is good to have sound knowledge of data structure concepts and algorithms.
- Apart from approaching the problem by following the steps mentioned above, it is important to give a real-time update about the complexity of the process and your method of circumventing it so that the discussion is on and the interviewer is keen to see your result.
System Design Interview Preparation
System design interviews have a lot of weightage in the entire interview process, so it is important to prepare for them before appearing for any FAANG company interviews. System design interview preparation can be divided into the following key points:
1. System Design Interview Preparation Books
Books are an ocean of resources. These books provide dense knowledge and are generally less preferred. However, if you find reading and highlighting important points more effective than watching course videos, then here are some books that might come in handy while preparing for system design interviews:
2. Refer to System Design Articles and Videos
There are plenty of interview articles and videos on the internet for aspiring software engineers, coding engineers, and tech leads to refer to while preparing for the technical interview. Articles and videos provide concise information unlike the books and hence is sometimes more preferred.
3. Interview Prep Courses
Acing FAANG interviews is difficult, and the process becomes unbearable if one enters the interview arena with no prior knowledge about the process. There are plenty of interview prep courses available to choose from. Interview Kickstart has courses specifically targeting job profiles at FAANG companies.

How To Use Cracking The Coding Interview Effectively
- May 25, 2018
What’s up everyone. Sam here from Byte-by-Byte.com and today I’m going to show you how to make the most out of this book. So how do we use Cracking the Coding Interview most effectively? And maybe a good question to ask now is, why do we really need a video on how to use Cracking the Coding Interview effectively in the first place? I realize that it seems a little weird that we would have a video on how to use a book. But I consider Cracking the Coding Interview to be much more of an encyclopedia than it is like an easy read where you would sit down in bed and read the book. And in the same way as with an encyclopedia you might want to have a guide for how to use the encyclopedia effectively for research. I think that it’s really important that we understand how to use Cracking the Coding Interview properly for preparing for our interviews.
Then there are also chapters at the end of the book which hopefully are going to be apparent. That they are on very specific topics. And a lot of these topics you don’t really need to go in depth into, unless that’s something that you are already an expert in. So for example if you were doing your interviews in Java you wouldn’t need to study the chapter on C and C++. And that leads me to my sort of core set of chapters that you should focus on. So the core chapters of this book that you really need to know are chapters 1 through 5 and 7 through 10. And this is in the most recent edition.

System Design Interview Sample Questions And Answers
For software engineers, software developers, and tech geniuses who are confused about how to prepare for a system design interview, here is one of the many suggestions any expert in the field would give: to practice sample questions. Here are a set of few sample system design interview questions and their sample answers:
1. What metrics should be used for monitoring a systemâs performance?
Sample Answer: The three commonly used metrics to assess a systemâs performance are Latency, Availability, and Throughput. An important feature of these metrics is that they allow the system designer to understand the userâs experience while using a particular system. Each of the metrics focuses on individual properties like latency is related to the speed at which a particular message is delivered, availability is referred to how often a system responds to the userâs input, and lastly, throughput helps in understanding the amount of data traveled to the user.
2. How would you add micro-services to an already existing E-commerce platform?
Sample Answer: Micro-services can be added by interconnecting platform APIs throughout a distributed system.
3. What is load balancing, and state its importance in system design?
Sample Answer: Load balancing helps improve the quality of a system design and hence is an essential process. The purpose is to allocate tasks across computing nodes to ensure the systemâs proper functionality. The two important load balancers are L4 and L7.

Listen To Every Detail
When interviewing, write down every detail of the problem to reference whenever you get stuck.
When in your mock interviews , practice your attentive listening.
Coding interviews are interactive an exchange of coding interview questions between the between the interviewer and interviewee. As such, you need to pay attention. Your active listening reveals the intelligence and inquisitiveness they are looking for.
When listening to a problem, you need to pay attention to all of the details. This is like gathering the ingredients to a recipe: youre not using it all in the first step.
When you listen to a problem, you need to be absolutely certain you heard it correctly so that you are not off to the races solving the wrong problem. Ask questions. Repeat it back. Asking for clarification is encouraged.
It is unlikely that the interviewer will give you information that does not relate to the problem.
Cracking the Coding Interview says:
Many candidates will hear the problem correctly. But ten minutes into developing an algorithm, some of the key details of the problem have been forgotten. Now they are in a situation where they actually cant solve the problem optimally.
If you find yourself stuck, ask yourself if you used all of the information in the problem.
What People Are Saying
|“I wish I had read this book 90 days ago. I wouldn’t have blown a great job that I really wanted. This book goes beyond the usual answers to questions likely to be asked. Instead of telling you what to think it teaches you HOW to think. If I had read this book first and knew what was coming I think I would have nailed it.”- J. Braun, Amazon.com
|“Bought this book 3 weeks before interview. Read the book twice with careful hand-writing practice on each question. Got Amazon offer. The interview had 4 questions and one was in the book.”- Larry, Amazon.com
|“This book is a must-have for any interview candidate. Not only does it give practice problems and detailed answers, but it also gives you good advice about how to approach the problems as well as what to expect. I used this book to prepare for my interviews with Microsoft, and Gayle’s insight gave me a great idea of how to prepare and how to ace the interview. I recommend this book to anyone who has a coding interview in their future.”- Michelle, Amazon.com

Ask Relevant And Thoughtful Questions
During the coding interview, you will write code, solve problems, and discuss this all with the interviewers. If there is any misunderstanding on your part, then ensure you ask questions. Nobody is perfect, and this shows you are confident enough to clarify things .before starting, which is essential as a coder.
Draw A Specific And Sufficiently Large Example
Create examples that cover a generic case and not an overly simplified one.
In your mock interviews, as every first step to solving your problem, you need to draw an example. The author of Cracking the Coding Interview cautions that interviewees commonly draw bad examples.
What is a bad example? They are too small and do not sufficiently convey a common case for the problem scenario.
The book illustrates a tree with only two branches: three cells in total. That tree is not sufficient for the problem space.
It is also possible for you to draw an example that later turns out isnt quite right.
But in a technical interview, everything can be adjusted. Go back and fix your example.
