Cracking the Coding Interview: How to Become a Web Developer

11 min

If you wish to crack the coding interview, mastery of the core basics of coding (html, CSS and JavaScript) is necessary, to get those first few jobs. As you progress, diversify, and learn more coding languages, you will naturally find it easier, answering complex coding questions, as your brain, gets used to thinking like a programmer.

Below, I list some of the basics tips to aid you in, cracking the coding interview.

1. Know Yourself: Are You a Lion or a Goat?

Many people, are entering programming to make money right?

But what many aspiring developers, don’t realize is that they already have the skills to pay the bills.

Becoming a web developer now, can be likened to becoming a doctor; everybody wants to get in, and make those big bucks.

But the problem is that, the market is saturated. In fact, GitHub, has over 65 million registered programmers. I am sure only about 0.000005% of that number, is employed in a lucrative, high paying job.

As such, you as a new programmer, has to stand out from this huge crowd of people.

now face, is that we have many people, who jump in on the train wargon, only to get the cash, forgetting the fact, that most people who have a programming mind, are nerds.

Personally, I feel nerds are ahead of the time, and I will explain.

For example, some few years ago, nerds loved reading comic books, and anime, but they were ostracized for their taste of entertainment.

But fast forward to present day, and many people swear to love the avenger movies, forgetting the fact that they are newbies in this game.

Regardless, if your motives for becoming a web developer, is monitary based, I will advise you to turn your portfolios, into a blog, that can bring in recurring revenue to you.

With money in your pockets, you will now have more freedom, to chase your dreams of becoming a qualified web developer.

Aside senior web developers, who are paid high salaries.

2. Know the Job

It’s always a good idea to thoroughly research the job before an interview. This will help you understand the responsibilities of the position, the company culture, and the expectations for the role. Here are some steps you can take to prepare for an interview:

  1. Review the job posting and make a list of the required skills and qualifications.
  2. Research the company and its industry. This can include looking at their website, reading news articles about them, and looking at their social media profiles.
  3. Consider how your skills and experiences align with the job requirements.
  4. Prepare answers to common interview questions, such as “Tell me about yourself,” “Why do you want to work for our company,” and “What are your strengths and weaknesses?”
  5. Think of specific examples and accomplishments that demonstrate your fit for the role.
  6. Practice your answers with a friend or family member to feel more confident in the interview.

By doing your research and preparation, you will be better able to showcase your fit for the role and stand out as a strong candidate.

3. Master Core Basics

You want to get hired as a developer. You are not trying to become a developer. There is a difference between somebody trying, and somebody who is.

As such you must have mastery over the basics of programming (coding), which are html, CSS and JavaScript, because few or even no person, will hire you, if you are not versed, in this basics.


HTML (HyperText Markup Language) is a markup language used to structure and present content on the World Wide Web. HTML is the standard markup language for creating web pages, and it allows you to specify how text, images, and other content should be displayed in a web browser.

HTML is used in conjunction with other technologies, such as Cascading Style Sheets (CSS) and JavaScript, to create dynamic and interactive websites.

<p>This is a paragraph.</p>

HTML consists of a series of elements, which are represented by tags. These tags tell the web browser how to format and display the content. For example, the following HTML code defines a paragraph element:

<a href="">This is a link</a>

HTML also allows you to add attributes to elements, which provide additional information about the element. For example, the following HTML code defines a link element with an href attribute that specifies the link’s destination:


Cascading Style Sheets (CSS) is a stylesheet language used to describe the look and formatting of a document written in HTML. CSS is used to control the style of a web document in a simple and easy-to-use way. With CSS, you can change the color, font, layout, and more for HTML elements. You can even control the appearance of multiple pages at once by creating a separate CSS file and linking it to your HTML files.

Here is an example of some simple CSS code that changes the text color of an HTML element with the class “my-class” to red:

.my-class {
  color: red;

This CSS code can be applied to an HTML element like this:

<p class="my-class">This text will be red</p>

Here is another example that changes the font size and font family of all h1 elements:

h1 {
  font-size: 32px;
  font-family: Arial, sans-serif;

This CSS code can be applied to an HTML element like this:

<h1>This is a big, Arial heading</h1>


JavaScript is a programming language that is commonly used in web development. It is used to create interactive effects within web browsers, such as drop-down menus, form validation, and interactive maps. JavaScript is often used alongside HTML and CSS to create dynamic and interactive web pages.

Here is a simple example of JavaScript code that displays an alert box when a button is clicked:

function showAlert() {
  alert("Hello, World!");

This JavaScript function can be called from an HTML button element like this:

<button onclick="showAlert()">Click me</button>

4. Invest in Yourself

Investing in yourself means taking the time and effort to improve yourself, your skills, and your knowledge. This can take many forms, such as pursuing education or training, building new skills through practice or experience, or setting goals and working to achieve them. Investing in yourself can have many benefits, including increasing your confidence, improving your employability and career prospects, and helping you to lead a more fulfilling and rewarding life.

There are many ways to invest in yourself, and the best approach will depend on your personal goals and circumstances. Some common ways to invest in yourself include:

Overall, investing in yourself is an important way to grow and improve as an individual, and can have lasting benefits for your personal and professional life.

5. Master Server Side Management

Server-side management refers to the administration and maintenance of servers, which are computer systems that store, process, and deliver data and resources to other devices over a network. There are many different responsibilities that come with server-side management, including:

  • Installing and configuring server hardware and software
  • Managing user accounts and permissions
  • Monitoring and optimizing server performance
  • Backing up and restoring data
  • Ensuring server security and compliance with regulations
  • Managing and troubleshooting network connectivity issues
  • Monitoring and managing server resources, such as storage and memory usage

To become a master at server-side management, you will need to have a strong foundation in computer science and networking concepts, as well as experience working with servers in a professional setting. This may involve earning a degree in a relevant field, gaining certifications, and gaining practical experience through internships or entry-level positions. It can also be helpful to keep up with new developments and best practices in the field by staying current with industry news and participating in continuing education opportunities.

6. Practice: Create Crude Application

A crude application is a simple or rudimentary application, typically one that is not fully developed or polished. The term “crude” can be used to describe an application that is functional but lacks advanced features or a polished user interface.

Crude applications are often used as proof-of-concepts, prototypes, or as a starting point for further development. They are generally not intended for widespread use or public release, but rather are used for internal testing or to demonstrate the feasibility of a particular idea.

In the context of learning to program or develop software, building crude applications can be a useful way to gain experience and practice your skills. You can start with simple, basic applications and gradually build up to more complex and feature-rich applications as you gain more experience and knowledge.

Here is an example of a simple “crude” application that you can create using HTML, CSS, and JavaScript:


<!DOCTYPE html>
    <title>My Crude Application</title>
    <h1>My Crude Application</h1>
    <p>Enter your name:</p>
    <input type="text" id="name-input">
    <button onclick="sayHello()">Say Hello</button>
    <p id="output"></p>


body {
  font-family: sans-serif;

h1 {
  color: blue;


function sayHello() {
  var name = document.getElementById("name-input").value;
  document.getElementById("output").innerHTML = "Hello, " + name + "!";

This application has an HTML form with a text input and a button. When the button is clicked, the JavaScript function is called, which gets the value of the text input and displays a greeting using the entered name.

This is a very basic example, but it should give you an idea of how you can use HTML, CSS, and JavaScript to create a simple application. You can expand on this example by adding more features and functionality.
