MCQ Screening Questions for a Frontend Developer
Use these 20 multiple-choice questions to quickly filter frontend developer applicants, even if you're not a technical expert.
Why MCQ Questions Work for Tech Screening
As a recruiter, you don't need to be able to code, but you do need to be able to spot a candidate who clearly doesn't know the basics. These Multiple-Choice Questions (MCQs) are your secret weapon. They test for core, factual knowledge that any qualified frontend developer should have. By automating this first pass, you ensure that the candidates who reach your technical team have a solid foundation, saving everyone time and frustration.
What to Look For in a Frontend Developer
Look for a solid understanding of the three pillars of the web: HTML, CSS, and JavaScript. Beyond that, modern frontend development requires familiarity with a component-based framework like React, experience with version control (Git), and the ability to consume data from APIs. These questions are designed to touch on all these key areas, giving you a well-rounded initial assessment of a candidate's technical knowledge.

"I'm a recruiter, not a developer. These questions allow me to have a baseline technical conversation and filter out candidates who clearly don't know the fundamentals."

How to Use These MCQ Questions
Select 3-5 of these questions and add them to a Sift quiz. The most effective strategy is to combine a few fundamental questions (like the meaning of HTML/CSS) with questions specific to your stack (like the React and TypeScript questions). Use the Sift quiz link in your job postings to automatically filter candidates. Only those who pass this initial knowledge check will be sent to your team for a full technical review.
Common Screening Mistakes
A common mistake is asking questions that are too obscure or trivial. The goal isn't to play 'gotcha,' but to verify a solid understanding of concepts used daily on the job. Another mistake is not having a clear pass/fail criterion. Every question in this list has a definitive correct answer, removing subjectivity and allowing you to screen with confidence.
