# Educative Io Grokking The Coding Interview

## Can A Behavioral Interview Course Really Help

Ace the JAVASCRIPT INTERVIEW Grokking the System Design Interview course review || educative.io

Absolutely. Affirmative. Yes!

Preparing for the behavioral interview is just like prepping for any other type of interview.

You wouldnt go to a coding interview without hashing out a few problems beforehand.

And you probably wouldnt go to a system design interview without doing a bit of research.

Data structures and algorithms? Not a chance youd go to that interview blindly.

And you shouldnt go to a behavioral interview without brushing up on your behavioral skills.

## How Grokking Dynamic Programming Patterns For Coding Interviews Helps

DP problems may seem hard at first and strike fear in ones heart, except one is trained to recognize the patterns in these problems and equipped with the right techniques to solve them.

This is where the course Grokking Dynamic Programming Patterns for Coding Interviews proves a valuable resource.

For example, heres the solution to the Fibonacci problem, a common dynamic programming problem explained in detail as outlined in the course:

Lets take the example of the Fibonacci numbers. As we all know, Fibonacci numbers are a series of numbers in which each number is the sum of the two preceding numbers. The first few Fibonacci numbers are 0, 1, 1, 2, 3, 5, and 8, and they continue on from there.If we are asked to calculate the nth Fibonacci number, we can do that with the following equation.

Fib = Fib + Fib, for n > 1

As we can clearly see here, to solve the overall problem ), we broke it down into two smaller sub-problems, and Fib). This shows that we can use DP to solve this problem.Below is the solution written in JavaScript:

`const calculateFibonacci = function  return fib } console.log //result is 5console.log //result is 8console.log //result is 13`

## Design Tinyurl Or Bitly

Given a long URL, how would how would you design service that would generate a shorter and unique alias for it.

Discuss things like:

• How to generate a unique ID for each URL?
• How would you generate unique IDs at scale ?
• How would you support custom short URLs?
• How to delete expired URLs etc?
• How to track click stats?

## Grokking Coding Patterns On Educativeio

Hi, did anybody here used “Grokking the Coding Interview: Patterns for Coding Questions”?

I want to know how the course is? and if it’s worth taking and anybody willing to sell it on a discount I am ready to buy.

eh, I did it. tbh it wasn’t worth it in my opinion. Its just the same interview questions that you find on leetcode, separated by techniques. Some of them that say medium or hard are now leetcode easy’s and mediums respectively when you search them up. You’re better off using leetcode and the discussions page imo than pay 80 bucks for it.

Also here is an article of all the techniques/patterns they go over and by go over I mean a short paragraph on what the technique is then just questions and solutions using said technique.

Im actually going to disagree with this opinion. I found myself lacking some unknown basics when doing leetcode and having a hard time picking up the patterns. I’m just a bit too old / ADHD to be able to learn efficiently through videos . I really appreciate the text format of this course and have found it to be exactly what I needed so far.

## How To Start Your Interview Prep

I think that for most people starting out in this interview prep process, LeetCode is pretty hard. Here are two possible starting problems, though the best point of entry is admittedly Cracking the Coding Interview.

• FizzBuzz on LeetCode. I recommend it because it should not require any additional interview preparation, and will help you familiarize yourself with the LeetCode platform.
• Jewels and Stones on LeetCode. If you are not able to solve this on your first try, then you will have to learn a technique that is useful in many coding interview problems.

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.

## Pattern: Fast & Slow Pointers

Another name for this topic is the tortoise and hare method.

It talks about the use of two pointers to determine the traits of a directional data structure.

In many cases, the technique is used to find out if there is a cyclic list in a set of data.

It becomes clear that there is a cycle in the given set of data when the two pointers used meet at a point.

This is part of what coding students will learn on the Grokking platform because knowledge of fast and slow pointers is important for organising data.

## Requirements And Goals Of The System

When designing a TinyURL-like application, there are some functional and non-functional requirements to consider.

Non-functional requirements:

• The system must be highly available. If the service fails, all the short links will not be functional.

• URL redirection should happen in real-time with minimal latency.

• Shortened links should not be predictable in any manner.

Functional requirements:

• When given a URL, our service will generate a shorter alias of the original URL. This new link will be extensively shortened so that it can be easily copied and pasted.

• Users should have the option to pick a custom short link for their URL.

• Short links will expire after a default timespan, but users are able to specify the expiration time.

## My Favorite Educative Courses For Coding Interviews And Software Development In 2022

Without wasting any more of your time, here is a list of the best interactive, text-based courses from Educative for programmers and software engineers.

These interactive text-based courses have been created by experts and Educatives state-of-the-art platform that makes learning easy with interactive quizzes, and the ability to run the program right from your browser.

## Take Ownership Of Your Education

Big Tech interviews are both fairly standard and widely documented. There is a wealth of resources to prepare for the coding interview and a growing pile of systems design resources.

Itâs easy to get lost in so much information: which is why you should make a plan on how you will get âinterview-readyâ.

Create a study plan with topics you want to cover for the interview types youâre expecting to have. Learn the theory, then practice this with practice and exercises where you create something from scratch: implementing a data structure, drawing up a diagram.

There is no shortage of people complaining about the difficult interview process Big Tech has. However, I know of no other industry where you can get a high-paying job with no college degree, no connections: purely through interviews that are fairly standard among the highest paying employers like Netflix, Airbnb, Uber, Facebook, Pinterest, and others.

Tech interviews being âstandardâ across the Big Tech makes preparing for these a high-leverage activity: study once, interview many times. Once you prepare, just make sure your software engineering resume grabs the attention of the recruiters.

Good luck â and if you are looking for more advice for senior and above interviews, I have some.

## Capacity Estimation And Constraints

Our system will be read-heavy. There will be a large number of redirection requests compared to new URL shortenings. LetÃ¢s assume a 100:1 ratio between read and write.

Traffic estimates: Assuming, we will have 500M new URL shortenings per month, with 100:1 read/write ratio, we can expect 50B redirections during the same period:

One thing to note here is that since there will be a lot of duplicate requests , our actual memory usage will be less than 170GB.

System Design interviews are arguably some of the most difficult for software engineers.

Making it even more challenging, many college computer science courses and coding bootcamps dont include system design in the curriculum.

Its designed to expose you to the most important elements of system design asked in FAANG-level interviews.

## Cracking The Coding Interview

Cracking the Coding Interview is still one of the best resources out there for interview prep, even in 2021. I have heard some people say that it is no longer sufficient, but I have had two coding interviews that were taken out of the book almost verbatim.

Unfortunately, this is not a free resource…but here is a LeetCode forum that maps every CTCI question to a LeetCode one.

The reason this is acceptable is that they are not perfect mappings. For example, the LeetCode String Compression problem is not exactly the same as its CTCI equivalent because it has an added constraint. It is actually harder than the CTCI version

If you do choose to purchase Cracking the Coding Interview, the solutions are all freely available on GitHub. They are in multiple programming languages, in case you are not a Java developer.

McDowell herself built the repository and committed the Java portion to it, so it is very unlikely the repository will removed due to copyright infringement.

Because interviews can be stressful.

This can lead to rambling, fumbling, spacing out, and an endless list of other unflattering side effects.

And its that nervous response that may lead to you not getting the jobEven if you do great with the technical stuff.

## What Is Grokking Dynamic Programming Patterns For Coding Interviews

The word Grokking is an English word that means to understand intuitively or by empathy.

Therefore, Grokking Dynamic Programming Patterns for Coding Interviews is an online course designed to mirror the standing of developers as novices and equip them with the different techniques necessary for recognizing and solving dynamic programming problems often asked in dynamic programming interviews, such as the Fibonacci Sequence mentioned above.

But what exactly is dynamic programming all about?

## Grokking The System Design Interview: Who Is This Course Really For

All in all, I really think Grokking the System Design Interview is a high-quality course.

However, its geared towards a specific subgroup of engineers with their sights set on top tech companies like Google and Amazon.

While this is a great course, I wouldnt recommend it to code newbies or new engineers as there is a high opportunity cost.

If youre wondering what I mean by that, check out this review of Cracking the Coding Interview.

If you want to stand out in front of the pack of hungry FAANG applicants, study the system design tools and problem-solving techniques featured in this course.

They just might do wonders for making you stand out when the big day comes to land that FAANG software engineering role.

And if you really want to grok til you drop, read my review on Grokking the Coding Interview.

In the words of RealToughCandy, everyone wants a “one-stop shop” when it comes to learning.

She uses this term to describe Educative.io, but Educative.io costs \$60 a month unless you choose to commit to its annual plan. So it’s not a free resource, which means it’s not available to everyone.

If money were not a factor, you might buy a copy of Cracking the Coding Interview, get a LeetCode Premium subscription, and sign up for access to Grokking the Coding Interview before scheduling some mock interviews.

Now, websites like LeetCode are interesting because they provide an excellent resource for free.A large percentage of LeetCode questions are free, the discussions section provides free solutions where the best code/explanations are voted to the top, and the platform itself can run hundreds of test cases in seconds.

Many people argue that LeetCode premium is not worth it, though writers like Yangshun Tay beg to differ. What interests me about LeetCode is not their premium option, but that they make so much of their service available without it.

All that being said, there are a number of quality free resources you can use to prepare for your coding interviews. Let’s go through my favorites now.
