How To Ace A Coding Interview In 3 Simple Steps

May 23, 2022 0 Comments


Coding is hard. It takes a lot of practice to become good at it, and even more, practice to get great at it.


But if you want to land a job as a developer, you're going to need to know how to code.


Your coding skills are among the most important factors that hiring managers look for when evaluating candidates. If you don't know how to code, your chances of getting an offer will be slim.


The good news is that there are ways you can prepare yourself for coding interviews. And if you follow these three steps, there's a guarantee that you'll ace your next coding interview. So let's get into it!


In the world of hiring, it's important to make a strong first impression. In fact, studies have shown that it takes about 7 seconds for someone to form a first impression of you! That's why we are here to give you some tips on how to make sure your coding interview is an A+ success. Whether you are interviewing for a front-end web developer position or an internship, these steps will help you prepare for your big day. 

We'll break down some common questions asked by interviewers and also give some tips on things like what to wear and do with your hands during the interview process - plus some much more helpful stuff too! 

These interviews can be very stressful so try not to worry too much about how things go (we know this is easier said than done!). Just remember that the interviewer wants you to succeed as much as they want their company's success in finding great people who fit its culture well. Use these steps below and we promise you'll do just fine!

Step 1: Practice solving problems on your own.

The first thing you need to do is practice solving problems on your own, with a whiteboard or paper. If you’re able to solve the problem in a few lines of code as possible, that’s great! But don't worry about syntax just yet. Just go for whatever solution comes naturally and try to have fun with it.

Step 2: Go over common patterns and algorithms.

As a software engineer, you'll need to know the basics. But don't worry the fundamentals are not as difficult as they seem.

Think of it this way:

When you're writing code for a computer, you're basically just telling it how to solve problems in the best possible way. And there are many ways that a computer can solve problems efficiently and effectively. The trick is knowing which approaches will help your program run faster or consume less memory (or whatever). So if you understand how different programming techniques work together, then picking up new languages and frameworks becomes much easier!

Step 3: Review common data structures and related topics.

Now that you've learned the basics of programming, it's important to review some common data structures and related topics.

  • Data structures: A data structure is a way to logically organize information. The most common data structure is a list, which is a container that contains other containers or primitive types of data. Some examples of lists include an array (elements are numbered), an associative array (elements are referenced by keys), and a linked list (elements are stored in memory locations after each other).


  • Common algorithms: Algorithms are instructions for solving problems, like how to calculate the area under a curve or sort numbers from lowest to highest. Some common algorithms include bubble sort and quicksort.


  • Patterns: A pattern is used repeatedly in software development processes because it works well at solving problems with similar requirements; for example, applying the Singleton Pattern would ensure that only one instance of an object exists at any given time so both client code and internal code can access it without worrying about creating more than one object at once!


  • Questions: You should expect interviewers will ask questions such as "What cool thing have you built recently?" They may also ask technical questions like solving Sudoku puzzles using recursion techniques; these types of questions can be tricky but this guide shows how they work step-by-step so don't worry!

With these steps, you'll be ready to ace your coding interview!

In order for this to work, you'll need to prepare in advance. Start by practising solving problems on your own. You can do this by taking a course or reviewing common patterns and algorithms online. Once you've mastered those fundamentals, take a look at some common data structures and related topics that you'll want to brush up on before the interview such as strings, binary search trees, queues and heaps.


By getting comfortable with the interview process and knowing what employers are looking for, you will be able to face your coding interviews with confidence. Remember that practice makes perfect so keep on doing mock interviews until you feel prepared. At the end of it all, try to remember that coding interviews aren’t just about being a good programmer; they’re about creating relationships and building trust. So be yourself, have fun, and make the most of this experience! Good luck!
