Specific mobile testing interview questions

If you're looking to work in mobile testing, hiring managers are likely to ask some specific mobile testing interview questions to assess your technical knowledge and skills. Preparing for these interview questions can help ensure you respond effectively and can help impress the interviewer. Employers often ask candidates these questions to ensure they're familiar with testing applications developed specifically for mobile devices to ensure they function correctly.

Testing is an integral part of the software development progress. Working in mobile testing often requires specific technical knowledge and strong analytical skills. Here are some specific questions you can expect:

  • What is your process for choosing the right test automation tools?

  • Do you use debugging tools for mobile applications?

  • When do you prefer to use manual testing instead of automatic testing?

  • Do you find automatic testing more efficient? If so, can you explain why?

  • Name a few differences between WAP and web testing.

  • Define a memory leak in relation to mobile testing.

  • What is the difference between a simulator and an emulator?

Questions relating to your experience

During the interview process, hiring managers ask specific questions about your professional experience and background. This can help them establish if you have the desired skills to perform the job tasks. Try to use real-life scenarios in your answers that show how you used a specific skill relating to the interview question. Examples can help a hiring manager visualise your skill level and understand how you approach different challenges at work. Here are some questions relating to your previous experience:

  • Why did you study your university degree?

  • Are you considering any further study or certifications?

  • Why are you interested in working at this organisation?

  • What's the biggest challenge you've faced during your career?

  • What's the most important thing you learned while studying?

  • Why do you think mobile testing is vital for businesses?

5 sample answers to common mobile testing questions

Here are some mobile testing questions and sample answers to help you better prepare for your job interview:

1. What skills are most beneficial to have as a mobile tester?

Having a range of hard and soft skills can benefit a mobile tester. In addition to the technical skills necessary to perform tasks, understanding how to collaborate with other team members and consider a client's perspective can also help. Hiring managers can ask this question to identify what skills you think are essential and what you can offer. When answering, try to provide a range of skills that you believe relate to the job duties in the job description.

Example: 'It's important for a mobile tester to have different skills, including hard and soft skills, to be successful. I've worked collaboratively in previous roles, so I understand that communication skills are typically vital to ensure everyone understands their responsibilities. Strong technical skills are also important for producing competent work. For example, a strong candidate generally knows at least basic programming and can document test plans.'

2. What are important factors to consider when testing a mobile application's security?

As a mobile tester, a key area of your responsibility can be to test for both usability and security. How you answer this question can help a hiring manager understand how much knowledge you have about these two areas. When answering, it's a good idea to reference two or three factors and describe why these are important.

Example: 'I believe that two of the most important factors relating to security when testing mobile applications are encrypting and decrypting sensitive data. Using the right tools can help protect most sensitive information that may disrupt business and create uncertainty if someone outside the organisation accessed it. I explore ways to offer multi-user support, which helps ensure only authorised individuals can log in and make adjustments.'

3. Can you explain the difference between a web application and a native application?

This interview question can help a hiring manager identify how familiar you are with different applications. This can be an excellent way for them to determine your general industry knowledge. When responding, aim to describe both applications, including their fundamental differences. It can also be worth including another type of application to demonstrate your expertise to the hiring manager.

Example: 'A web application operates using a mobile web browser, while a native application is one that users download to their mobile device. In addition to these two applications, there are also hybrid applications. Hybrid applications usually use HTML5, CSS and other web technologies. One benefit of hybrid applications is that you can access these apps even if you're offline from your mobile device.'

4. What are some common bugs you may find during the mobile testing process?

This question also tests your technical ability to show that you can identify some common issues mobile testers typically face. Aim to talk about three to four bugs and provide a short overview of each to demonstrate your knowledge. You can cover more than four to highlight your expertise if there's time.

Example: 'Generally, the most frequently found bugs fall into four different types: critical, block, major and minor. Critical bugs relate to when a device's operating system crashes during testing of an application. Block bugs are when the device is unresponsive, even when the device status is on. Major bugs relate to a specific feature of an application that cannot perform correctly. Finally, a minor bug typically relates to an issue with the graphic user interface.'

5. Explain a testing strategy for a new mobile app and what you would include.

When a hiring manager asks this type of question, they're testing your technical capabilities and your approach for planning and strategy. When answering, aim to demonstrate your technical competency and explain why you've chosen an approach. Your preferred method can help hiring managers to understand your capabilities, workflow and ability to think independently.

Example: 'When creating a comprehensive test strategy, it's essential to understand the market's demand when selecting suitable testing devices. I would usually involve key stakeholders in this decision. Sometimes, it's helpful to use emulators to check the app quickly, but it's often important to consider various types of testing based on the objectives of the test strategy. For example, functional, system integration, HTML control, performance, gateway, network, installation or battery testing may be appropriate depending on the specific objective.'
