CSS Developer Test

Use a CSS test to hire web developers by testing their knowledge and understanding of styling websites using CSS.

  • What is a CSS test?

    A CSS test is an effective way to assess the skills and abilities of a web developer.

    The test uses multiple questions based on all things CSS to help evaluate an individual's strength and understanding of a range of CSS topics. This includes using basic style properties, advanced properties, and pre-processors (including layout, fonts, and colours).

    The ability to fix any front-end bugs, use simple code to perform a design task and understand general best practices for building websites is essential to doing well at this assessment.

    CSS stands for Cascading Style Sheets and is critical for front-end development roles, as it allows for web pages and applications to be designed and branded using HTML markup.

    The test uses a multiple-choice format and can be sent to applicants during the early stages of your recruitment process. This allows you to shortlist top-quality candidates, providing you more time to invest in applicants later on (such as for interviews and assessment days).

    The test is timed, adding an element of pressure so you can see which candidates work well with deadlines and have good time management.

  • Reduce costs and time.

    No more laborious sifting of resumes or cover letters. Pick your ideal assessment mix, invite your applicants to take them, see the results in your dashboard. Get to the interview stage fast.

  • Eliminate bias.

    All your candidates take the assessments on a level playing field. Only their results determine whether they get shortlisted.

  • Why is a CSS test so important when hiring?

    Using a CSS programming test during your recruitment process is an easy and efficient way to ensure you are selecting top talent based on skills that traditional methods of recruitment do not offer.

    Trying to assess programming knowledge such as CSS is difficult from just reading a resume or application. Portfolios of work can be more useful in this scenario, but it is difficult to assess how much of the applicant's code has actually been written by them.

    That's where a CSS test can be beneficial. The cost of making a bad hire is detrimental to software and development teams, so using a CSS test can reduce your chances of this happening.

    Using a CSS test provides HR teams and recruiters with 4 core benefits including:

    1. Makes decisions data-driven, so shortlisting is easier

    2. Reduces unconscious bias during recruitment

    3. Provides comparative data, so you can rank candidates in order of strengths

    4. Helps you recruit for skillsets you might not fully understand

How to assess CSS coding skills using our test

Our CSS test asks a variety of questions that vary in difficulty level. Candidates who are proficient in CSS should be able to answer the questions correctly.

The CSS test provides valuable data-driven insight into what a candidate knows and understands. The test is structured using multiple-choice questions: a familiar format for most test-takers, that allows for instant and objective scoring.

As well as the correct answer, there are typically 2–4 distractors, representing common misconceptions and mistakes. This helps make the test more challenging, so a candidate's ability can be measured more accurately.

Test scores are provided to the user and can be compared to other test-takers in your talent pool to see how they perform relative to each other.

Each test has been thoroughly reviewed to ensure accuracy and validity in line with industry standards. It has been written, examined and edited by CSS experts and psychometric professionals. It has also been reviewed by a diverse sample of job seekers to check for any issues including sensitivity, face validity, fairness and accessibility.

This test is continually monitored so our team can optimize performance and regularly assess fairness issues.
