Coding interview questions usually cover data structures. Generally, they will include questions such as reversing arrays and converting them into zigzag fashion. They will also test your knowledge of the Pythagorean theorem and the smallest and largest subarray. This post focuses on will help you to prepare for a coding interview in 3 days

Write a project portfolio
In writing a project portfolio for a coding interview, keep the following guidelines in mind: Keep it short and concise. You don’t want to make your portfolio look like a maze. Instead, it should present your skills and achievements in a way that makes it easy to navigate. It can also be helpful to include testimonials from satisfied clients. Whether they are actual people or companies, this will add credibility to your claims.
The projects section is one of the most important parts of your portfolio. This is where you can showcase your creative skills and achievements. For example, if you’re a TDD wizard or a Design Pattern ninja, you should include relevant projects.
Remember that the interviewer is busy and has seen hundreds of resumes and talked to candidates just like you. Make sure that your projects are interesting to the interviewer. A good project is something that is popular, but it doesn’t have to be one that has 100,000 users.

A good project portfolio can help you land a coding job. You can show how you solve problems and present solutions. You can also include your contributions to team projects, which could help you land the job. Also, make sure to include the aspects of the project that relate to the job.
Read a Good Programming Book
One of the best ways to prepare for a coding interview is by reading a good programming book. It is a great way to get familiar with the questions you’ll be asked in your interview and the etiquette of programming. The book also has sections that focus on the problem-solving aspect of coding.
This book is more comprehensive than other programming books you’ll see at the library. It covers everything from basic concepts and algorithms to more advanced techniques. It also explains older technologies such as vacuum tubes and transistors. It also covers topics such as the von Neumann architecture, floating-point arithmetic, and operating systems.
The Big Machine book is a great resource for people who want to learn how to code. It’s a practical guide to software development and features a mix of basic to advanced questions on a variety of topics. It also covers the skills you need to succeed at your coding interview.
You can also learn problem-solving strategies that will help you design efficient solutions quickly. These strategies are repeated throughout the problem-solving process. These strategies include descriptive variable names, good coding style, and testing for edge cases. By learning these strategies, you’ll be able to answer the questions asked in the interview with greater confidence and a competitive edge.
Practise Coding
If you’re preparing for a coding interview, there are three key things you should do right away. First, make sure you understand the question that’s asked during the interview. You don’t want to be the candidate who just retypes code and expects the interviewer to understand. The interviewer wants to know why you’re writing the code that you’re writing.
It is also important to remember that the interviewer wants to see that you can solve a problem quickly, so it’s crucial to have the right skills to communicate your ideas. This includes having descriptive variable names, writing a good code style, and testing for edge cases. Keeping these things in mind will make you stand out from the rest of the candidates and help you get through the interview.
Another important tip is to practice coding questions with a timer. The coding questions that are asked on the coding interview are often questions that require you to solve data structure problems. Some of the most common questions include reversing arrays, converting arrays into zig-zag fashion, and Pythagorean functions.
Practicing coding problems in various languages is an excellent way to practice your answers. This will make you more confident. You can even find a website that offers sample coding questions that are frequently asked in interviews and practice them. These practice sessions can help you develop your confidence and your self-esteem as well.
Another essential tip for 3 day coding interview preparation is to practise debugging. This will help you become more comfortable solving algorithmic problems. It is a big part of writing software, so you should be familiar with debugging techniques. A good debugging tool that you can use is pdb. There are other debuggers out there that can be helpful, so try them out before the coding interview.
Dress Appropriately
Dressing smartly for a coding job interview is essential, even if the company has a relaxed work culture. You should wear a smart, conservative outfit, at least a level above the company’s dress code. The best places to find out the dress code are on the company’s social media pages or careers page. The recruiter will also be able to tell you about any requirements. You may need to bring your laptop.
Many companies leverage their offices as publicity tools. If you’re attending a company interview, consider how your appearance will be interpreted by other employees. For example, if you’re applying to a startup, you should dress appropriately for the type of work environment you’ll be in.
You should research the company’s dress code to ensure you’re dressing properly. You can research the company on social media or call current employees to get an idea of what the company’s dress code is. Avoid wearing any bright colors or jewelry, since this can distract the interviewer. You should also avoid wearing large earrings and jeans. Wear simple, clean clothing that will enable you to focus on the questions you’ll be asked.
In most cases, an IT developer or software engineer will have a more casual on-the-job dress code, but if the company is looking for a VP-level candidate, they will be more formal. However, it’s always smart to dress for the interview. It’s better to invest a little time in your wardrobe rather than a lot of time and money. The effort will pay off as the interviewee will be more confident and at ease.
Working with a Debugger
Using a debugger is one of the best ways to prepare for a coding interview. Interviewers look for problems that repeat themselves. When solving these problems, candidates can cache calculated results to save time. Moreover, they can only start coding when the interviewer gives the green light.
It’s a good idea to emulate a debugger while walking through the code to note down values of variables. Bugs in code are often the result of copy and pasting code. So, try to write some test cases as you step through the code.
Another way to prepare for a coding interview is to read and practice debugging code in a live environment. It’s best to choose an application that’s similar to the language that you’ll be applying for. This way, you’ll get a better feel for how to use the tools and how to read the code.
After a week or two, you’ll have a decent grasp of the basic concepts of programming. For example, you may be asked to merge two arrays with different indexes. This will require you to use a binary search, or a partially-sorted array. You should also know how to use the Min Heap to solve this problem. The more you practice, the better you’ll become at answering the questions.
In preparing for a coding interview in 3 days it is helpful to spend time on the core essentials for coding and trouble shooting.
Learning how to use tools is an essential skill for any software developer. With so many powerful tools available, it’s important to learn how to use them efficiently. Knowing how to use a debugger can help you pinpoint errors. Learning to use a debugger in your programming projects will be invaluable to your coding interview preparation.
