Typical coding interviews are designed to test your ability to write good code and solve problems on your own. Learn how to be a competent programmer, and also how to hone your problem-solving skills to prepare for coding interviews.
This is so that you have at least one common language to share with your interviewer. Assuming that your interviewer is also a good programmer, they should be able to understand any of theses languages without much trouble. And work on tons of personal projects. It's by far the easiest way to build your programming experience and skills. So make something that you're interested in. Open-source or volunteering work is also a good way to practice coding. Internships, contracting work, or even regular paid jobs are also great ways to practice coding because not only do you get to have more experience with these, you could also get paid.
Step two for preparing for coding interviews is honing your problem-solving skills. To do this, you should practice solving as many problems as possible, and when you're solving these problems, I would write down your solution on paper first and then actually try running it to make sure it's correct. This is because you might need to write your solution on a whiteboard in the actual coding interview. I would highly, highly recommend practicing with others too. You should get your friends to give you mock interviews and you should given them mock interviews in return.
This way, you get to see what it's like in the interviewer's shoes too, and that's going to be really helpful when you have real interviews. In this course, I'm going to give you a sample coding interview problem to work on after reviewing each concept the we're going to cover, for example, two-dimensional rate. My recommendation here would be to try solving each problem on your own first for practice and then watch the solution videos when you're done or stuck. After you're done with this course, if you're looking for more problems to work on or something more advanced, I want to recommend two more resources here.
The first one is leetcode.com. It's a website where you can practice solving coding to your problems and compare your performance with others. The second one is a book called Cracking the Coding Interview. It's somewhat more advanced, but it's a really good book for preparing for coding interviews, especially with large companies like Amazon and Microsoft.
Follow YK Sugishita as he explains what to keep in mind as you prepare for coding interviews. YK covers useful concepts that can help you master your interview, followed by practice problems that test what you know. YK reviews key concepts such as two-dimensional arrays, time complexity, Big-O notation, and hash tables. To wrap up, he shares a few tips for acing your interview, such as how to come up with an optimal solution. Even if you're not prepping for an upcoming job interview, tackling the coding problems covered in this course is a great way to sharpen your programming skills.
