Top 76 UX Design Interview Questions And Answers

Question 1

What are the most popular usability methods?

Accepted Answer

UX researchers have developed many techniques over the years for testing and validating product hypothesis and particular design decisions. The methods range from well-known lab-based usability studies to those that have been more recently developed. In this article, we will explore seven different usability testing methods when you should use them and why.Before you pick a particular testing method, you should have a clear understanding of your target audience, available resources (time and money), and research objectives. This information not only will help you select the relevant testing method but also adjust the questions and tasks for your test participants:

* **Guerilla testing** is the simplest form of usability testing. Basically, guerrilla testing means going into a public place such as a coffee shop to ask people about your prototype. Test participants are chosen randomly.Guerilla testing works best in the early stages of the product development process.
* **Unmoderated remote usability testing** occurs remotely without a moderator. It offers quick, robust, and inexpensive user testing results to be used for further analysis. Test participants are asked to complete tasks in their own environment using their own devices and without a moderator present, which leads to the product being used naturally. The cost of unmoderated testing is lower; however, this type of testing offers less detailed testing results. Unmoderated remote usability testing works the best when you need to obtain a large sample to prove critical findings from your initial moderated research.
* **Contextual inquiry** is less a usability testing method and more like an interview/observation method that helps a product team obtain information about the user experience from the real users.This technique is useful for getting rich information about users— their workspace, personal preferences, and habits.
* **Card sorting** is an excellent method for prioritizing content and features in user interface. The technique is relatively simple—all you need to do is place concepts (content, features) on cards and allow test participants to manipulate the cards into groups and categories.Card sorting is great when you want to optimize your product’s information architecture.

Question 2

What are  the top UX research methods and when to use them?

Accepted Answer

Here are some examples of the types of user research performed at each phase of a project.

* Card Sorting: Allows users to group and sort a site’s information into a logical structure that will typically drive navigation and the site’s information architecture. This helps ensure that the site structure matches the way users think.

* Contextual Interviews: Enables the observation of users in their natural environment, giving you a better understanding of the way users work.

* First Click Testing: A testing method focused on navigation, which can be performed on a functioning website, a prototype, or a wireframe.

* Focus Groups: Moderated discussion with a group of users, allowing insight into user attitudes, ideas, and desires.

* Heuristic Evaluation/Expert Review: A group of usability experts evaluating a website against a list of established guidelines.

* Interviews: One-on-one discussions with users show how a particular user works. They enable you to get detailed information about a user’s attitudes, desires, and experiences.

* Parallel Design: A design methodology that involves several designers pursuing the same effort simultaneously but independently, with the intention to combine the best aspects of each for the ultimate solution.

* Personas: The creation of a representative user based on available data and user interviews. Though the personal details of the persona may be fictional, the information used to create the user type is not.

* Prototyping: Allows the design team to explore ideas before implementing them by creating a mock-up of the site. A prototype can range from a paper mock-up to interactive HTML pages.

* Surveys: A series of questions asked to multiple users of your website that help you learn about the people who visit your site.

* System Usability Scale (SUS): SUS is a technology-independent ten-item scale for subjective evaluation of the usability.

* Task Analysis: Involves learning about user goals, including what users want to do on your website, and helps you understand the tasks that users will perform on your site.

* Usability Testing: Identifies user frustrations and problems with a site through one-on-one sessions where a “real-life” user performs tasks on the site being studied.

* Use Cases: Provide a description of how users use a particular feature of your website. They provide a detailed look at how users interact with the site, including the steps users take to accomplish each task.

Question 3

What are the different types of usability testing?

Accepted Answer

There are a few different types of usability testing or reasons to conduct usability research:

* **Comparative Usability Testing**. Used to compare the usability of one website with another. Comparative tests are commonly used to compare a website against peer or competitor sites, however it can also be used to compare two designs to establish which provides the best user experience.

* **Explorative Usability Testing**. Before a new product is released, explorative usability testing can establish what content and functionality a new product should include to meet the needs of its users. Users test a range of different services where they are given realistic scenarios to complete which helps to highlight any gaps in the market that can be taken advantage of and illustrate where to focus design effort.

Question 4

What is usability testing?

Accepted Answer

Usability testing is a method used to evaluate how easy a website is to use. The tests take place with real users to measure how ‘usable’ or ‘intuitive’ a website is and how easy it is for users to reach their goals.The key difference between usability testing and traditional testing (bug testing, acceptance testing etc.) is that usability testing takes place with actual users or customers of the product. Whilst traditional testing might be undertaken by a developer, designer or project manager, usability testing removes any bias by collecting feedback direct from the end user.

Usability testing can be used in a variety of ways during your project lifecycle. Despite not being able to mimic real life usage, usability testing is still the best method of ensuring your website supports users in achieving their goals quickly and easily. When businesses meet the needs and expectations of their users, they are more likely to develop a successful service.

Question 5

Name some basic design elements

Accepted Answer

The elements of design are:

* **LINE** – The linear marks made with a pen or brush or the edge created when two shapes meet.
* **SHAPE** – A shape is a self contained defined area of geometric (squares and circles), or organic (free formed shapes or natural shapes). A positive shape automatically creates a negative shape.
* **DIRECTION** – All lines have direction – Horizontal, Vertical or Oblique. Horizontal suggests calmness, stability and tranquillity. Vertical gives a feeling of balance, formality and alertness. Oblique suggests movement and action
* **SIZE** – Size is simply the relationship of the area occupied by one shape to that of another.
* **TEXTURE** – Texture is the surface quality of a shape – rough, smooth, soft hard glossy etc.
* **COLOUR** – Colour is light reflected off objects. Color has three main characteristics: hue or its name (red, green, blue, etc.), value (how light or dark it is), and intensity (how bright or dull it is).

Question 6

What are the advantages and disadvantages of usability testing?

Accepted Answer

There are many **advantages** of usability testing including:

* feedback direct from the target audience to focus the project team
* internal debates can be resolved by testing the issue to see how users react to the different options being discussed
* issues and potential problems are highlighted before the product is launched

The business advantages of usability testing can be seen at the end of the project:

* it increases the likelihood of usage and repeat usage
* it minimises the risk of the product failing
* users are better able to reach their goals, which results in the business meeting its targets

**Disadvantages**.Usability testing provides many benefits, but there are a few disadvantages in using this methodology, which should be noted. Firstly, testing is not 100% representative of the real life scenario, e.g. a mother will not have her two young children running around like she might have at home. Also, usability testing is mainly qualitative, so does not provide the large samples of feedback that a questionnaire might, but the feedback can be far more accurate and insightful.

Question 7

The importance of prototyping in designing?

Accepted Answer

The prototype is an important draft design that precedes the development of the original design layout. It is intended not only to show the structure of the future site, but also the site map, the interrelation of its main pages. Prototyping is a process designed to significantly reduce the time to develop a site, due to the focus of the designer on the main functional and marketing factors:
* The prototype gives the customer a complete idea of ​​how the site will look like in the final result;
* Prototyping allows you to streamline the design development process, focusing on important interface elements;
* A site’s sketch is an irreplaceable thing if the client still does not fully understand what he expects from the site, what functions each page will carry. Careful planning at the prototyping stage makes it possible to avoid global changes in the finished layout;
* At the prototyping stage, it is possible to identify unnecessary elements that are best abandoned;
* This process significantly reduces the workload of the designer in developing the project, and thus saves the customer’s money;
* Having a prototype in hand, the designer and customer more clearly represent the final result;
* Prototype development involves the involvement of the customer, contributes to more productive work, process consistency.

Having a prototype makes it easier to understand the tasks for each team member. It gives them the opportunity to do more realistic planning of development deadlines and more accurately determine the cost of work. Website development in strict accordance with the prototype allows not taking into account the cost of changes and modifications.

Question 8

What is the prototyping process?

Accepted Answer

Prototyping is the 4th step of the design thinking process.Before you determine how you should go about the prototyping process, you have to have identified the users, defined their problem, and brainstormed and selected a proper solution in the form of a product or service.
Listed below are the steps in the prototyping methodology:

* **Identify Obstacles** .Start by brainstorming with your team to identify any obstacles that may delay or block your prototyping or product designing process. Having these identified prior to designing will allow you to take precautions.

* **Select the Features**.You prototype won’t be able to represent all the product features, therefore you might want to select the key features that will help you gather as much feedback from the user as possible.

* **Sketch Your Design** .You can do this on a piece of paper or a diagramming tool like Creately which provides complete libraries for wireframes, UI mockups, flowcharts, mind maps etc.

* **Share Your Design** .Share your design with partners, stakeholders etc. Ask for their feedback and mark where you need to make modifications to the design based on their requirements.

* **Continue to Develop** .Apply changes and develop your prototype by adding more features. Once it’s ready, you can share it with your stakeholders, partners, users etc. again for their feedback.

Question 9

What are user research methods?

Accepted Answer

There are two main types of user research: quantitative (statistics: can be calculated and computed; focuses on numbers and mathematical calculations) and qualitative (insights: concerned with descriptions, which can be observed but cannot be computed).

**Quantitative research** is primarily exploratory research and is used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics. Some common data collection methods include various forms of surveys – online surveys, paper surveys, mobile surveys and kiosk surveys, longitudinal studies, website interceptors, online polls, and systematic observations.

**Qualitative user research** is a direct assessment of behavior based on observation. It’s about understanding people’s beliefs and practices on their terms. It can involve several different methods including contextual observation, ethnographic studies, interviews, field studies, and moderated usability tests.

Question 10

What is user experience (UX) research?

Accepted Answer

User Experience (UX) research is the process of discovering the behaviors, motivations and needs of your customers through observation, task analysis, and other types of user feedback. Understand the user experience for new products, websites, mobile apps and prototypes.
UX research helps brands and organisations accomplish the following:

* Understand the user experience for new products, websites, mobile apps and prototypes
* Make informed decisions through the product development process by testing various aspects of product designs
* Discover, optimise and evaluate the genuine user experience
* Understand each user interaction prior to conversion
* Nail the design and experience early in a product’s life cycle
