Top UI/UX designer interview questions and answers for freshers
1. What are the critical stages of the UX design process?
One of the main UI UX designer interview questions and answers is regarding the stages of the UX design process.
UX design, short for user experience design, is creating products or websites that provide meaningful and relevant experiences to the users of a website. This involves designing the complete process of acquiring and integrating the product. It also includes numerous aspects of branding, design, usability, and function.
- Research and analysis: The UX designer collects data about the user's needs and goals in the research and analysis stage. This data can be accumulated through interviews, surveys, focus groups, and usability testing.
- Design: After the research and analysis stage, the UX designer begins to design the product's user interface and interactions. This involves creating wireframes, storyboards, user flows, and other visuals to illustrate how the user will interact with the product.
- Prototyping: Develop interactive prototypes that simulate the user experience, allowing stakeholders to test and validate the product's functionality and flow.
- User testing: Once the UX designer has designed the product, they will conduct user tests to determine how well the product meets the user's needs. This involves having real people interact with the product to identify improvement areas.
- Refinement: After user testing, the UX designer will make adjustments to the product's design based on the user's feedback. This may involve changing the user interface, adding features, or making other changes to improve the user experience.
2. What methods do you use to conduct user research?
As a UI/UX developer, several methods can be used to acquire the insights necessary to create a successful user interface or experience. Some of them are:
- User interviews
- Surveys and questionnaires
- Contextual inquiry
- Usability testing
- Heatmaps and Analytics
- Prototype testing
- Remote testing
3. How do you ensure user accessibility in your designs?
What value is a product if it is not accessible to everyone? This is why 'user accessibility is the most common UX interview question that you can be asked.
A key component of accessibility is providing excellent and consistent content that conveys essential information to all users, regardless of their abilities.
- This includes using features such as headings, labels, alternative text for images, descriptive link text, and alt text for short phrases.
- It also means making sure the text size is legible, and that color contrast is adequate, so color-deficient users can easily understand the text.
- One should consider keyboard shortcuts, confirmation, and error messages, and ways to skip navigation bars. This helps users to quickly navigate to the main action or content and helps keep any confusion to a minimum.
Finally, you need to test and evaluate the accessibility of your design. Remember that accessibility should be considered from the start of the design process. Tools such as automatic checkers can help quickly identify areas where the design may fall short of expectations and need work. Another helpful tool is user feedback, where you can ask users with disabilities to test the design and provide valuable input on making it more accessible.
4. What are some common usability issues, and how do you address them?
As a UI/UX developer, several common usability issues can arise. These can range from the user experience being too confusing or complicated to the design layout not being intuitive or easily navigable.
- One of the most common usability issues is creating a user flow that is difficult to follow, leading to user frustration and difficulty converting users. To address this issue, a strategic analysis of user flow should be conducted, and any necessary changes implemented into the design, making it more user-friendly. Additionally, ensuring that solutions are context-specific and tailored to a specific target audience is vital when addressing usability issues.
- Another common usability issue that may arise is having too many features in the design, creating an overload of information. This can cause confusion, as it can be difficult to distinguish the most crucial information. To address this issue, developers should decide what necessary features should be present in the user journey and work towards showcasing the most impactful features for the user.
- Finally, you must also consider the device the users will be interacting with the design on, as it needs to be optimized for all devices. This includes testing for loading speeds, potential bugs, and responsiveness, as issues such as these can severely impact user experience. To address potential device-related problems, you can design mobile versions of their web pages, ensuring a smoother user experience for people interacting with the design on a mobile phone.
5. How are you updated with the latest UI/UX trends and best practices?

7. Differentiate between CSS Reset and Normalize.css
A CSS Reset is a set of codes used to reset the styling of HTML elements to a baseline. This is important because different browsers may display HTML elements differently by default. A reset eliminates the inconsistencies and ensures elements appear the same across all browsers.
Normalize.css is a more modernized approach to creating a style reset that works much better than legacy resets. Normalize.css preserves valuable browser defaults, such as bold on links and using background colors to indicate certain elements while still providing consistency across browsers. This gives developers more control over the design rather than being forced to start from scratch. Another unique advantage is that due to its popularity, Normalize.css is also implemented in many popular CSS frameworks like Bootstrap and Materialize, making it much easier to get started.
8. How do you ensure that your designs are accessible to people with disabilities?
- Familiarize yourself with accessibility guidelines:
Learn about WCAG (Web Content Accessibility Guidelines) and ARIA (Accessible Rich Internet Applications) standards. These guidelines provide comprehensive information on making digital content accessible to individuals with disabilities.
- Semantic HTML:
Use semantic HTML elements properly to provide structure and meaning to your content. This includes using headings, lists, and semantic elements like <nav>, <main>, and <footer>.
- Alternative text for images:
Always include descriptive alt text for images. It will help users with visual impairments understand the content and context of the picture.
- Keyboard navigation:
Ensure that all interactive elements (buttons, links, form fields) can be easily navigated and operated using a keyboard alone, without relying on a mouse or touchpad.
- Focus indicators:
Make sure there are visible focus indicators for interactive elements. Users should be able to see which component has keyboard focus.
- Color contrast:
Maintain a good level of color contrast between text and background to make content readable for users with low vision or color blindness.
- Descriptive link text:
Use clear and descriptive link text that provides context for the link's purpose. Avoid using generic catchphrases such as "click here" or "read more."
- Form labels:
Associate form labels with input fields using the <label> element or ARIA roles to ensure that screen readers can identify the purpose of each field.
- Testing with assistive technologies:
Regularly test your designs with assistive technologies such as screen readers (e.g., JAWS, NVDA, VoiceOver) and screen magnifiers. This helps identify accessibility issues.
- Captions and transcripts:
Provide captions or transcripts for all audio and video content. This benefits users who are deaf or hard of hearing and also helps with SEO.
Since this is the most common UI UX designer interview question, make sure you answer it correctly.
9. Differentiate between responsive design and adaptive design.
ã…¤ | Responsive Design | Adaptive Design |
Approach | Responsive design uses a single layout that adapts fluidly to different screen sizes. | Adaptive design involves creating separate layouts for specific device categories. |
Flexibility | Responsive design offers a more flexible and continuous adaptation of content. | Adaptive design provides more precise control over the user experience for each device. |
Development | Responsive design can be easier to implement because it involves a single set of code and relies heavily on CSS media queries. | Adaptive design can be more complex because it requires creating and maintaining multiple layouts and often involves server-side detection. |
10. Differentiate between the <b> and <strong> tags.
ã…¤ | <b> Tag (Bold) | <strong> Tag (Strong Importance) |
Use | The <b> tag is used to apply bold formatting to text. | It is often used to highlight key terms, emphasize important content, or add weight to certain words or phrases. |
Meaning | It does not convey any specific semantic meaning to the enclosed text. | The <strong> tag in coding indicates that the enclosed text is of strong significance. It carries semantic meaning. |
Purpose | It is primarily used for purely presentational purposes to make text appear visually bold. | It has SEO benefits because search engines may interpret the text within <strong> tags as more important or relevant. |
Significance | It carries no additional weight regarding search engine optimization (SEO) or accessibility. | It also enhances accessibility, as screen readers and other assistive technologies may convey the importance of the text enclosed in <strong> tags to users. |
11. What is the Box model in CSS?
The box model is one of the most fundamental concepts in CSS (Cascading Style Sheets) that describes how elements in a web page are structured and how their dimensions are calculated. It comprises several layers or components, forming a "box" around each HTML element. These components determine the element's layout and appearance. The core components of the box model are:
Content:
- This is the innermost part of the box and represents the actual content of the HTML element, such as text, images, or other media.
Padding:
- Padding is the space that is given between the content and the element's border. It provides internal spacing and separation between the content and the border. Padding can be set by using the padding property in CSS.
Border:
- The border surrounds the padding and content areas, forming a visual boundary around the element. It is defined using the border property in CSS.
Margin:
- The margin is the space outside the border, separating one element from another. It controls the spacing between elements on the page. Margins can be set by using the margin property in CSS.

12. What is JavaScript Hoisting?
JavaScript hoisting is a programming mechanism in which variables and functions are moved to the top of their scope before code execution. In layman's terms, this means that JavaScript declarations are made available in the scope of the entire program, even if they are declared within a specific block of code. Hoisting was implemented to simplify JavaScript programming and make it efficient to use.
An example of hoisting is seen when a JavaScript variable is declared after use. When this happens, the JavaScript compiler hoists the variable to the top of the scope to make it available even before it is declared. In other words, although it is written after its use, the variable is treated as if it was declared before its use, thus saving time and effort.
Also, hoisting works with functions, too. All function declarations are moved to the top of their scope when JavaScript is compiled, so you can use a function before it is written in the code. Additionally, when a function expression is used, the expression is not hoisted, but the variable declaration is added to the scope.
13. Differentiate between local storage, session storage, and cookies.
ã…¤ | Local Storage | Session Storage | Cookies |
Lifespan | Data stored in local storage persists indefinitely until explicitly removed by the user or the web application. | Data stored in session storage persists only for the duration of a page session. It is cleared when the session ends, typically when the user closes the browser or the tab. | Cookies can have different lifespans, including session cookies (cleared when the browser is closed) and persistent cookies (with specified expiration dates). |
Storage Capacity | It typically offers more storage space than cookies, with a limit of around 5-10 MB, depending on the browser. | Similar to local storage, session storage provides storage space of around 5-10 MB, depending on the browser. | Cookies typically have a minimal storage capacity of 4KB per cookie and a maximum of around 50 cookies per domain. |
Accessibility | Data stored in local storage is accessible across browser sessions and tabs. It is not limited to a single browser window. | Data is accessible only within the same page session. It is not shared across browser tabs or windows. | Cookies can be accessed across sessions, tabs, and windows. They are sent with every HTTP request to the domain. |
Scope | Data is stored with the same origin policy, accessible only to pages from the exact domain/origin. This provides security and privacy. | Like local storage, session storage follows the same-origin policy and is limited to the domain/origin. | Cookies can be set to different access levels, including domain-wide cookies, subdomain cookies, and path-specific cookies. |
Usage | Local storage is commonly used for storing non-sensitive data that should persist across sessions, such as user preferences, cached data, or application state. | Session storage is often used for temporary storage of data needed only during a single user session, such as shopping cart contents or form data. | Cookies are often used for tasks like session management, user authentication, tracking user preferences, and analytics. However, they are not suitable for storing large amounts of data due to their size limitations. |
14. What techniques and tools do you employ to enhance web performance through image optimization?

15. What is Semantic HTML?
Semantic HTML is the use of HTML markup elements that carry meaning or semantic value, indicating the structure and purpose of content within a web page. Semantic HTML is essential for creating well-structured, accessible, and search engine-friendly web pages. It helps both humans and machines (like search engines and assistive technologies) understand the content and its context. Some semantic tags are:
- <section>
- <header>
- <mark>
- <details>
- <summary>
- <figure>
- <footer>
- <main>
