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 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 skill set, 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 know where to go for further improvement.
1. Data Structure and Algorithms Analysis — Job Interview
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 interview.

2. Software Engineer Interview Unleashed
This is one of the great courses for coding interviews, created by a former Google Interviewer. If you are a software engineer and you are looking for a job on big tech giants like Google, Facebook, SnapChat, or Airbnb, then this is the right course for you.
It is specially designed for college graduates and junior developers who are looking for a job in big technology companies and startups.
You will not only learn data structure and algorithms and other technical information required for an interview but also you will get a chance to see actual examples of phone and onsite interviews and see how they are evaluated.
3. Preparing For a Job Interview
This one is another good course for preparing technical job interviews. In this course, instructor John Sonmez, author of best-selling book, Soft Skills: The software developer’s life manual has explained what it takes to clear a coding interview.
In this course, you will not only learn how to solve a coding challenge on-the-spot but also learn how to tackle tricky questions from interviewer with respect to complexity and improvement.
The course also includes a blazing fast boot camp for computer science questions about data structures, algorithms, bit manipulation, and concurrency. Overall, a complete package for preparing software job interviews.
4. The Coding Interview Bootcamp: Algorithms + Data Structures
In this course, you will find a huge collection of common algorithm questions, including everything from “reversing a string” to “finding leaf nodes of the binary tree.”
The course also provides an overview of most important data structures for interviews e.g. list, set, map, stack, queue, tree, etc.
It also provides practical tips on dealing with system design interview, which is sometimes hard for beginners given their lack of experience in designing a real-world system…..Read More>>>
