@ javinpaul Javin Paul I am Java programmer, blogger on http://javarevisited.blogspot.com and http://java67.com

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.

reactions

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.

reactions

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.

reactions

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.

reactions

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?

reactions

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.

reactions

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.

reactions

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.

reactions

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.

reactions

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.

reactions

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.

reactions

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.

reactions

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.

reactions

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

reactions

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.

reactions

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

reactions

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

reactions

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.

reactions

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.

reactions

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.

reactions

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.”

reactions

The course also provides an overview of most important data structures for interviews e.g. list, set, map, stack, queue, tree, etc.

reactions

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.

reactions

This is another good interview refresher kind of course for Java and C programmers. Similar to the previous course it also covers essential concepts like pointers, string, linked list, sorting, bit manipulation, data structure, and system design.

reactions

Most of the solutions are given in the C programming language and some are given in Java.

reactions

This is a good course for fresh engineer graduate and experienced programmers who want to brush up their data structure and algorithm concepts before going for interviews.

reactions

Many coding problems can be easily solved if you know dynamic programming but I have found many developers doesn’t even know about it, including some experienced ones.

reactions

This course will teach you dynamic programming to improve your algorithms knowledge and prepare for the software engineering coding interview.
