10 Data Structure, Algorithms, and Programming Courses to Crack Any Coding Interview
Tags: Java, Programming, Coding, Interview, Software Development

Many junior developers dream of making it at one of the larger tech companies, but, to be honest with you, getting your first job is never easy. It is, in fact, one of the hardest things in your life and you need to put your best effort to find a job in your dream company.

Most of the computer science graduates dream of working for Google, Facebook, Amazon, Microsoft, and Apple but only a few programmers clear their difficult coding interviews.

The single most important reason for failing those coding job interviews is the lack of knowledge and practice. It pretty obvious that if you don’t know what to learn then you are bound to fail, hence it becomes increasingly important that you prepare hard in advance.

Unfortunately, I learned this a little too late, after spoiling my chances at Microsoft and Amazon, but you don’t need to. You can learn from my experience and prepare better for your programming job interviews.

So, the big question is, how do you prepare for coding/programming job interviews? Which subjects should you read up on? Which questions will you need to solve? How do you deal with coding and other technology related questions?

When I was hunting for my first job there wasn’t much help available; we were totally reliant on our textbooks of programming languages and data structure to prepare for interviews, but things have changed in the last 10 years.

Nowadays, you not only have dedicated books to prepare for the coding interview, like Crack the Coding Interview Questions, but you have online courses and Coding Bootcamps to practice for coding interviews.

I really like the boot camps because of their methodology, focus, and rigorous practice but they are a bit expensive and not every computer science graduate who is looking for a job can afford that.

Another option is online courses like Software Engineer Interview Unleashed, which are both cheap and provide you similar kind of interactive guidance you get in coding boot camps.

There are a lot of coding interview courses available on popular course sites like Udemy and PluralSight but you need to choose the right course which can help you to achieve your goal.

10+ Data Structure and Algorithm Courses for Programming Interviews

In this article, I am going to share some of the best online courses to prepare for coding/programming job interviews, and based upon your experience and skillset, you can choose one or two courses from this list to prepare for your next job interview.

Most of these courses are focused on data structure and algorithms, which are the most important topics for any coding interview but they also teach you problem-solving and other aspects of Job interview e.g. questions from a programming language like Java and C++, Database, and SQL concepts, Linux commands, etc.

Once you have gone through one of these online training courses, you would have enough knowledge to take on your job interview as well as know where to go for further improvement.

This is probably the best coding interview course for Java programmers. Though no programming language is required, if you don’t know Java, the author will teach you.

In this course, you will learn how to analyze algorithms like searching, sorting, and other algorithms.

You will also learn how to reduce the code complexity from one Big-O level to another level, an important skill to impress the interviewer.

Furthermore, you will learn different types of data structures and how to choose the right data structure to solve a problem.

Remember, choosing the right data structure can drastically improve the CPU and memory profile of an application.

For example, using a set to solve duplicate elements problem make it a lot easier. You will also learn how to find Big-O for every data structure.

By the end, you will be able to write code that runs faster and uses low memory. You also will learn how to analyze problems using one technique many programmers forgot to prepare.

This is an ideal course for all levels of programmers, particularly Java programmers. If you are looking for a good programming/coding interview course in Java, this is the one. You can use it to start from scratch or just refresh your knowledge before going to an interview.

If you have attended coding interviews then you may know that dealing with System design questions is not easy, especially if you don’t have much experience in real-world software development.



Things like caching, scalability, fault-tolerance, Microservices, database design are important to design software but not easy to master. This course provides a good introduction to all the things you can keep in mind while designing a new system like a website, an application, or just an app.



This course is a must if you want to crack the coding interview but even if you are not preparing for an interview, you will learn a lot about software architect and design by going through this course which will eventually make you a better programmer.
