Top 10 Courses to Crack Java Programming Interviews in 2020 - Best of Lot

Hello guys, if you are preparing for Java interviews like for a core Java developer role in a big Investment bank like JP Morgan, Morgan Stanley, etc, or a Java web developer in service-based companies like Infosys, TCS, LuxSoft, Tech Mahindra, IBM, and Cognizant, and looking for some awesome courses and material, then you have come to the right place. Earlier, I have shared the best coding interview courses which focused on essential coding interview skills like Data Structure and Algorithms, SQL, Linux, etc.  While those are still very good to prepare for any coding interview including the Java developer role and you can use them to build your programming fundamentals. 

In this article, I am going to share some of the best online courses you can take to prepare key topics like core Java, multithreading, concurrency, algorithms, data structure, system design, design patterns, and software architecture.  These are some advanced courses that focus on programming job interviews by sharing helpful questions and teaching you techniques to answer them.



10 Best Courses to Crack Java Programming Interviews in 2020

Without wasting any more of your time, here is my list of 10 online courses to crack any Java Programming interviews. I have included courses to cover essential coding skills like Data Structure and Algorithms, Problem-solving, Core Java, Concurrency, Design Patterns, and Software Design, Object-oriented programming, SQL, and Spring Framework with Spring Boot.

1. Grokking the Coding Interview: Patterns for Coding Questions

One of the most essential things to crack any programming job interview is your ability to apply whatever you have learned to a completely unknown problem. This is very important becuase sometimes you will face questions which you have never heard before, and you need to solve them right there. This course helps you to build those patterns in your mind.

It will teach you some of the most useful techniques you can apply to coding problems and break it down into a known pattern. 

For example, you can use Stack to convert a recursive solution to an iterative one. You can divide a number by 10 to get rid of the last digit and take the remainder to get the last digit. Similarly, a stack is very useful for parsing, etc.

2. Java Interview Guide: 200+ Interview Questions and Answers

This is your one-stop-shop for all kinds of traditional Java interview questions you can expect in companies. It covers Java questions from telephonic round to face-to-face round and covers all essential topics like collections, generics, concurrency, core java, etc.

If you need to buy just one course for your Java interview preparation, then you should buy this course. It is also very affordable.



3. Grokking the Object-Oriented Design Interview

Another important topic in Java interviews is object-oriented analysis and design. You will be either given a requirement like design a vending machine or coffee machine and need to code in 2-hour or so with unit test, or you will be involved in verbal discussion.

If you have never done any object-oriented analysis and design, then this is a great course, not just to prepare for an interview but also to learn from real examples.



4. Grokking the System Design Interview

System design is closely related to OOP design and analysis but focuses on the much bigger picture at component and tier level rather than class level. In order to solve system design questions like designing a website like Amazon, or designing a complex system handling millions of orders.

You need to know a lot of stuff to solve these problems from caching to DB interaction, from scaling to load-balancing, and how the distribution system works.

If you have never done this before, don't worry, this course will walk you through some common system design problems from companies like Amazon, Apple, Facebook, Microsoft, Google, IBM, etc. to give you enough knowledge and skills to crack system design question on your Interview. In short, one of the best system design course for Java interviews.

5. Java Multithreading for Senior Engineering Interviews

Concurrency in Java is one of the most complex and advanced topics brought up during senior engineering interviews. Knowledge of concurrency and multithreading can put interviewees at a considerable advantage.

This course lays the foundations of advanced concurrency and multithreading and explains concepts such as Monitors and Deferred Callbacks in depth. This is also one skill that can separate you from the crowd, and this course is great for building necessary concurrency skills.

You will practice some common concurrency problems from programming interviews and learn some key techniques an concepts like latch, barriers, synchronization, race-conditions, etc.

All the above four courses from the Educative platform. You have options either to buy these courses or go for the Educative subscription which costs around $18 per month (45% discount) and gives you access to their 100+ software development and coding courses. I prefer the subscription because sometimes you just need that flexibly to join the course whenever you want without going into all the hassle of buying it

7. 200+ SQL Interview Questions

SQL is another topic that is very common in Java interviews. Good knowledge of SQL and Database concepts like normalization and query optimization goes a long way in securing a job and working on a complex project. 

This course is good to prepare for an SQL Developer Interview with these 200+ real World SQL Questions and Practical Answers. Btw, if you are new to SQL and Database then you can also check out these best SQL courses to build and revise some SQL and database fundamentals.

9. Grokking Dynamic Programming Patterns for Coding Interviews

You might know that Dynamic Programming (DP) problems can be some of the most intimidating on a coding interview.  Even when it's actually clear if a problem can be solved using DP (which it rarely is), it can be pretty challenging to even know where to start on the solution. Unless that is, you're trained on the approach to solving DP problems.

This course is made from scratch with just that goal in mind. It'll equip you with a set of easy-to-understand techniques to handle any DP problem. Rather than just having you try to memorize solutions, you'll be walked through five underlying DP patterns that can then be applied to solve 35+ DP problems. In other words, one of the best dynamic programming course for coding interviews.

8. Data Structure and Algorithms Analysis - Job Interview

Along with SQL, Data Structure and Algorithms are two other skills that are very common in interviews. In fact, those are so important that if you don't brush upon them, you will not go past the telephonic round in most interviews. This course can be used to level-up your Data structure and algorithms skills before  Java interviews.

9. Design Patterns in Java

Design patterns are like concurrency, an essential skill for Java developers. It's expected from senior developers that they know about all object-oriented patterns and understands when to use them in your code. If you don't know about design patterns or GOF design patterns then this course will help you to discover the modern implementation of design patterns in Java, a must-have course for senior Java developers.

10. Spring and Spring Boot Interview Guide

Spring and Spring Boot is probably the most important framework for Java developers. The interviewer expects you to know how to work on Spring and Spring Boot project, and that's why there will always be some questions on this topic. This is a good course to prepare for Spring interview questions as you will learn to answer 200 interview questions on Spring, Spring Boot, and Spring MVC

That's all about some of the best courses to crack your next Java interviews. These courses cover some of the most essential topics for any programming job interviews and useful for both core Java developer looking to get into big investment banks like Goldman, Morgan, and others
and Java web developers working on service-based companies like Infosys, TCS, Wipro, Cognizant, Tech Mahindra, and others.
