Why use skills assessments for assessing UI/UX designer?
Incorporating skills assessments into your hiring process ensures you select the best UI/UX designers. Skills assessments objectively measure a candidateās abilities beyond whatās possible to gauge through resumes and interviews alone.

By using these assessments, HR professionals and CXOs can make data-driven decisions, ensuring that candidates possess the technical skills and creative thinking required for the role. This approach streamlines the hiring process and increases the likelihood of finding designers who can elevate your digital products and user experiences. Additionally, it helps identify potential growth and training areas, ensuring long-term success for your design team.
When should you ask these questions in the hiring process?
The best method for including UI/UX designer interview questions is to invite applicants to complete a skills assessment at the start of the hiring process. This initial step helps filter out candidates needing more technical proficiency and design aptitude. By leveraging platforms like Testlify, you can objectively evaluate their abilities in key areas such as coding, user interface design, and familiarity with essential tools.
Once candidates have passed the skills assessment, proceed with the interview phase. During this stage, use targeted interview questions to delve deeper into their problem-solving skills, creative thinking, and ability to collaborate with cross-functional teams. This two-step approach ensures that you invest time in candidates who have already demonstrated their technical skills. This allows the interview to focus on assessing your organization’s cultural fit and potential for growth.
