Once you’ve graduated from bootcamp coding , it’s time to start your job search. Like many programming jobs, front-end web development positions often require rigorous interviews and you will need to know how to prepare. Before going into details, it should be noted that coding tasks often include more than the typical " because you are fit for the job ‚" routine . While this is important (you have to make a good impression), you may also need to demonstrate your skills to your potential employer.

In this article, we’ll cover three common interview questions with front-end developers, along with some tips and tricks to help you complete the process. The purpose of this article is not necessarily to give you the answers, on the contrary, we aim to give you an idea of ‚Äã‚Äãwhat to study and what to expect from a job interview.

Programming challenges: a necessary evil

gray laptop on wooden desk — Programming challenges are a slightly risky use of your time , but are often needed in today’s tech job market.

Employers often offer new developers coding challenges to test their skills. Every business will have a different challenge and some are more difficult than others. However, an experienced and experienced web developer should be able to do this.

While it is necessary to prove your qualifications to employers, we have a brief warning for you regarding coding challenges. Sometimes companies may try to use your experience for free, giving you a complex problem to solve, then move on to the next candidate. Some companies have been surprised to use the c code. There are challenges in their software, although they never hired the person who wrote it. Fortunately, this kind of bad practice doesn’t happen often, but it’s something all new developers should be aware of.

As you prepare for the interview interview questions, there are a few things you should know beforehand. to register. Be prepared to answer any questions involving CSS and JavaScript, as these are important for the position you are applying for.

CSS Questions and Challenges

If you are looking for front-end development work, surely you have extensive knowledge now of CSS. It’s quite common for hiring managers to present CSS-based challenges to new applicants. We’ll take a look at two examples to give you a better idea of ‚Äã‚Äãwhat to expect. Although every business is different, many new hires in web development report questions similar to these.

Mixin

Companies often appreciate the experience of using Mixin blocks because they save a lot of time. Remember, it’s all about efficiency!

If you don’t know what Mixin is yet, here’s a brief description: it’s a block of grouped CSS declarations that you can reuse throughout your site. It’s also easy to use: just write @include, then the name Mixin and a semicolon.

CSS Rules

Another common topic that comes up during the interview is CSS rules. You will be asked to explain them and possibly show how to use them. You may be presented with a stylesheet and an opportunity to show your ability to follow it.

JavaScript questions and challenges

As a front-end developer, JavaScript is your best friend. At this point, you shouldn’t be a stranger to this universally useful web development language. Businesses expect this, so you can expect to receive a great set of questions for front-end developer interviews related to JavaScript. As mentioned above, all businesses are different, so you should do your best to be prepared for anything that might happen to you. Usually JavaScript challenges take a long time but are fairly straightforward. Here are some commonly used examples.

Palindrome Challenge ¬Æ

This is a classic challenge that requires a little effort to be right. a palindrome is a word that reads the same in both senses, like "mom‚" and "race car.‚" The object of the challenge is to reverse the string and return a "true‚" value if you have a palindrome. and return a "false" value if you don’t have one.

Finding vowels

This challenge is as easy as fun, but it’s still a very common question for interviews with front-end developers. The goal is simple: write a function to return the number of vowels in the input word. You can probably figure it out for yourself- same, but you can find many examples in lig born.

There’s usually no way of knowing what questions or challenges you’ll face before the interview, so don’t stress yourself out too much. Before you get there, there are some great ways to get a head start. You can try all of these challenges on your own and practice standing thinking. In many cases, hiring managers allow candidates to complete the challenge at home if it is complicated, so you will have ample opportunity to solve it. Here are our final suggestions for completing the rest of the interview.

Company search: do not go to the interview without knowing anything about your potential employer. It is always important to know as much as possible about the company and the position you are applying for.

Dress the party: Tech companies have a reputation for casual clothing and a relaxed attitude to technical aspects of the workplace old-fashioned, which is not entirely undeserved ; However, it is still important to do your best to appear professional during the interview (unless otherwise specified).

Showcase a professional portfolio and CV: Make sure your CV and portfolio are organized, relevant and presentable. This is your best chance, outside of the interview itself, to prove your qualifications. Take the time to choose relevant projects and always check your resume and cover letter for errors.
