[![10+ Online Courses for Programming/Technical Interviews](https://thepracticaldev.s3.amazonaws.com/i/nh6mbo214e8ilvt3ynda.jpg)] (https://academy.zerotomastery.io/p/master-the-coding-interview-data-structures-algorithms?affcode=441520_zytgk2dn)

Many junior developers dream of making it to 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](http://javarevisited.blogspot.sg/2012/01/google-interview-questions-answers-top.html), [Facebook](http://javarevisited.blogspot.sg/2015/02/50-programmer-phone-interview-questions-answers.html), [Amazon](http://javarevisited.blogspot.sg/2016/01/top-20-amazon-and-google-programming-interview-questions.html), [Microsoft](http://javarevisited.blogspot.sg/2015/12/30-microsoft-interview-questions-for-software-development-engineers.html), 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](https://pluralsight.pxf.io/c/1193463/424552/7490?u=https%3A%2F%2Fwww.pluralsight.com%2Fcourses%2Fdeveloper-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*](http://www.amazon.com/Cracking-Coding-Interview-6th-Edition/dp/0984782850/?tag=javamysqlanta-20)*,* but you have [online courses](https://click.linksynergy.com/fs-bin/click?id=JVFxdTr9V80&subid=0&offerid=562016.1&type=10&tmpid=14538&RD_PARM1=https%3A%2F%2Fwww.udemy.com%2Fdata-structure-and-algorithms-analysis%2F) and Coding Bootcamps to practice for coding interviews.

[![best coding interview courses](https://cdn-images-1.medium.com/max/600/0*tzHjzcWXnxF6k4qp.png)](http://www.amazon.com/Cracking-Coding-Interview-6th-Edition/dp/0984782850/?tag=javamysqlanta-20)

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](https://click.linksynergy.com/fs-bin/click?id=JVFxdTr9V80&subid=0&offerid=562016.1&type=10&tmpid=14538&RD_PARM1=https%3A%2F%2Fwww.udemy.com%2Fsoftware-engineer-interview-unleashed%2F), 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](http://javarevisited.blogspot.sg/2018/01/top-10-udemy-courses-for-java-and-web-developers.html) and [PluralSight](http://javarevisited.blogspot.sg/2017/12/top-10-pluralsight-courses-java-and-web-developers.html#axzz53viuJDer) but you need to choose the right course which can help you to achieve your goal.

## 10 Online Courses to Crack Programming Interviews
In this article, I am going to share some of the [best online courses to prepare for coding/programming job interviews](https://javarevisited.blogspot.com/2018/02/10-courses-to-prepare-for-programming-job-interviews.html), 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](https://hackernoon.com/50-data-structure-and-algorithms-interview-questions-for-programmers-b4b1ac61f5b0), 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](http://www.java67.com/2018/08/top-10-free-java-courses-for-beginners-experienced-developers.html) and [C++](http://www.java67.com/2018/02/5-free-cpp-courses-to-learn-programming.html), [Database](https://javarevisited.blogspot.com/2018/05/top-5-sql-and-database-courses-to-learn-online.html), and [SQL](http://www.java67.com/2018/02/5-free-oracle-and-microsoft-sql-server-online-courses.html) concepts, [Linux commands](http://www.java67.com/2018/02/5-free-linux-unix-courses-for-programmers-learn-online.html), 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 know where to go for further improvement.

### [1\. Master the Coding Interview: Data Structures + Algorithms](https://click.linksynergy.com/deeplink?id=JVFxdTr9V80&mid=39197&murl=https%3A%2F%2Fwww.udemy.com%2Fcourse%2Fmaster-the-coding-interview-data-structures-algorithms%2F)

This is probably the [best coding interview course](https://click.linksynergy.com/deeplink?id=JVFxdTr9V80&mid=39197&murl=https%3A%2F%2Fwww.udemy.com%2Fcourse%2Fmaster-the-coding-interview-data-structures-algorithms%2F) 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](https://javarevisited.blogspot.com/2017/04/recursive-binary-search-algorithm-in-java-example.html), [sorting](http://www.java67.com/2018/03/how-to-implement-radix-sort-in-java.html), 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](http://www.java67.com/2018/06/data-structure-and-algorithm-interview-questions-programmers.html) 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](https://javarevisited.blogspot.com/2018/04/how-to-find-k-missing-numbers-in-array-java.html) 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.

### 2\. [Grokking the Coding Interview: Patterns for Coding Questions](https://www.educative.io/collection/5668639101419520/5671464854355968?affiliate_id=5073518643380224)

This one is another fantastic course from the [Educative](https://www.educative.io/subscription?affiliate_id=5073518643380224) platform for preparing for coding interviews. Unlike other online courses where you prepare for coding interviews by solving problems, this course will teach you how to find *underlying coding patterns* so that you can solve similar problems on coding interviews.

This technique of finding patterns and developing coding sense is a must if you want to crack a coding interview on companies like [Google](https://medium.com/javarevisited/5-best-programming-languages-to-get-a-sofware-developer-job-in-google-3d8c83c444d6), [Microsoft](https://javarevisited.blogspot.com/2015/12/30-microsoft-interview-questions-for-software-development-engineers.html#axzz5YWjgMMkL), [Amazon](https://javarevisited.blogspot.com/2016/01/top-20-amazon-and-google-programming-interview-questions.html), Apple, Facebook, Netflix, or any FAANG companies. Why? because they often give you a coding problem that you have never seen before. If you know how to break the problem into recognized patterns you can solve them.

I highly recommend this course to anyone who is preparing for coding interviews but just like the previous course, even if you are not preparing for an interview, you can join this course to improving your coding skill and become a better developer.

You will also learn several 1-dimensional and 2-dimensional dynamic programming problems and how to derive the recurrence relation and write a [recursive solution](https://javarevisited.blogspot.com/2017/04/recursive-binary-search-algorithm-in-java-example.html) to it, then write a to the problem and code it up in a few minutes.

[![best technical interview courses](https://cdn-images-1.medium.com/max/600/0*1pqFA8dYP0V3dPmJ.png)](https://click.linksynergy.com/fs-bin/click?id=JVFxdTr9V80&subid=0&offerid=562016.1&type=10&tmpid=14538&RD_PARM1=https%3A%2F%2Fwww.udemy.com%2Fdynamic-programming%2F)

Some of the dynamic programming problems covered in this course are:

1.  Climbing stairs
2.  Buying and Selling Stock
3.  0/1 Knapsack
4.  Longest Common Substring
5.  Longest Common Subsequence

Overall a [good course to learn Dynamic programming](https://medium.com/javarevisited/6-best-dynamic-programming-courses-for-coding-interviews-14744060923c). You can take this course even if you are not preparing for a coding job interview, just to improve your knowledge of dynamic programming and algorithms. The course uses both [Java](https://javarevisited.blogspot.com/2018/08/top-5-free-java-8-and-9-courses-for-programmers.html) and [Python](http://javarevisited.blogspot.sg/2018/03/top-5-courses-to-learn-python-in-2018.html), so its useful for both Java and Python developers.

That's all about some of the best courses to prepare for coding/programming job interviews. As I said, the key to success in the coding interview is the ability to think through the problem and code in real-time.

You need a lot of practice to get that. Thankfully, there are a lot of websites where you can practice coding questions. Once you have gone through one of these courses, you can try solving my list of [50 coding problems](http://javarevisited.blogspot.com/2017/07/top-50-java-programs-from-coding-Interviews.html).
