45 Questions to Ask About Mobile Apps in an Interview (With Sample Answers)
Before a company puts out a new mobile app, they make sure it works well and meets their quality standards by putting it through a series of tests. The job of mobile app testers is to run these tests, look for problems, and work with app developers to find solutions. If you want to work as a mobile app tester, you might want to look over some of the most common interview questions for this field. This article will help you prepare for your next job interview by giving you 45 questions about mobile apps and some sample answers.
10 mobile apps interview questions
Here are 10 questions about mobile apps that you might be asked during your interview, along with examples of how to answer them in a professional way:
1. Can you explain what WAP is and why it’s important?
Hiring managers may ask you this question to see if you know the most common words and phrases that mobile app testers use at work. Give a short explanation of what this term means, how it is used, and some of its main benefits.
Example: “WAP stands for Wireless Application Protocol. It’s important because it helps the network run smoothly. We can also put mobile apps on other platforms with WAP, which makes testing them easier.”
2. What kinds of tests do professionals usually do when they use the standard Android strategy?
People who test mobile apps need to know how to do so on different operating systems. A hiring manager might ask you this question to find out how familiar you are with apps made for Android devices. Most of the time, you would do the following tests to answer this question:
Example: “Android’s standard plan has four main tests. These tests include the integration test, the unit test, the system test, and the operation test.”
3.Can you explain the different ways that manual tests and automated tests are used?
You can save time and get more accurate results if you know when to use each of these tests. Explain what each test is mostly used for in your answer.
Example: “Professionals usually use automatic tests when they need to do a lot of mobile app regression testing. This can save a lot of time, especially when it comes to things that are very important. But if an app only needs to be tested a few times, many professionals choose to test it by hand instead. For example, if I need to test a new function for an existing app, I might choose to run tests by hand instead of automating them.”
What are some of the most common problems you’ve found when testing mobile apps?
Mobile app testers may find a number of problems when they look at how well an app works. You can run tests better if you know what the most common problems are. Talk about two or three common problems you’ve seen and how you’ve helped mobile app developers fix them.
Example: “When I test mobile apps, one of the most common problems I run into is that they work too slowly. I time how long it takes for apps to start up and load different screens when I test them. If something in an app takes more than one or two seconds to do, I work with the developers to make it faster and better for the user. I’ve also worked with people who make mobile apps to help them make apps that use less battery power and let people use them for longer.”
5. What are the three main types of apps for mobile devices?
Even though the answer might seem obvious, hiring managers may ask this question to see how familiar you are with working with different kinds of mobile apps. In your answer, name and briefly describe each of the three types.
Example: “There are three kinds of mobile apps: native apps, mobile web apps, and hybrid apps. The people who make apps make apps that only work on one platform. People can get these apps from an app store. On the other hand, you can’t use a phone or other mobile device to open a web app without a web browser. Most developers don’t think of these sites as apps but rather as mobile websites. Last, hybrid apps combine these two ideas to use website content in a new way as a mobile app.”
6.Can you explain what testing for usability is and why it’s important?
Usability testing, which is also known as “user experience testing,” is a common way for mobile app testers and developers to find out if an app meets the needs and wants of its target audience. Give a quick summary of how to take this test and what kind of information you can get from it.
Example: “When we test a mobile app, usability testing is often one of the last things we do. During this phase, we ask a small group of end users to test the app and give us feedback on how it works. This helps us find problems and make sure the app works well on a wide range of devices. It also helps us make the app more flexible and add new features that make it easier for people to use.”
7.During a user interface test, what are some things you might want to pay attention to?
Testers of mobile apps do user interface (UI) tests to see how the app works for users and get feedback. List some of the most important parts of a mobile app that you could ask users to review to improve how it looks and how it works.
Example: “When I do UI tests, my main goal is to find out if the app is easy for people to use and looks nice. I ask users how they feel about things like the overall color scheme, theme, screen orientation, and resolution. I also want to know if the menu is easy to use and how long the page usually takes to load.”
8. What does compatibility testing mean, and why is it so important?
Compatibility testing, which is also called “nonfunctional testing,” is the process of checking to see if an app can run on different operating systems. Hiring managers might ask you this question to see how much experience you have with this important part of testing a mobile app. In your answer, explain what this test does and why it is important to do it.
Example: “Compatibility testing is a common way to find out which operating systems, networks, and platforms an application can run well on. We can also find hardware options that will work together by using compatibility tests. This is important because it tells us where we can sell apps and what kinds of devices people will need to use them.”
9. What do you think about when choosing a test automation tool to test a mobile app?
Hiring managers might ask you this question to see if you can pick the right test automation tools for each project. In your answer, explain some of the most important things you look for in a test automation tool and why these things are important.
Example: “The first thing I look for in an automation tool is whether or not it works on more than one platform. This is important because we might be able to expand the app to more platforms and operating systems in the future, even if we only launch it on one platform at first. Next, I would check how well the script works and make sure that the automation tool has the basic jailbreak requirements we need to test the app.
This is important because it will help us figure out how to help users whose devices’ ROMs have been changed. Lastly, I’d look for a tool that automates OS upgrades and lets the source code be shared.”
10.Describe a simulator and an emulator.
Simulators and emulators are common tools for testing mobile apps, so hiring managers may ask you this question to see if you have used them before. Explain what each tool is and why mobile app testers use it in your answer.
Example: “Simulators are used by people who test mobile apps to act like electronic networks. This tool helps us connect to our home network so we don’t have to use roaming services. An emulator is a piece of software that lets us test mobile apps without needing to use a real phone. When we use these tools, we don’t have to buy each device and operating system to see how well a mobile app works on it. We’ll save a lot of money by doing this.”
