1.

Why is proper user on-boarding so crucial to the success of a mobile app?

Onboarding is the series of screens that a user will see once they download an app. The purpose of these screens is to show the new user the benefits and features of the app, walk the user through the full registration process and collect information so that the app can be personalized to the user. The interviewer would like to know that you understand the importance of taking proper onboarding action.

Rachelle's Answer #1

"Proper onboarding is very important because it will directly impact whether a user decides if your app is what they need and were expecting. By showing off the functions, benefits, and features, you are solidifying with the user that your app is valuable."

Rachelle's Answer #2

"Successful first impressions are everything so, for that reason, every mobile app should have a solid onboarding series. I have worked on apps that onboard new users with a focus on features and benefits, while some apps are more focused on user personalization. A great onboarding experience will solidify ongoing user engagement."

2.

Why are push notifications so crucial to the success of a mobile app?

Push notifications are small messages that pop up on a mobile device, pushed out as reminders, from the apps they have downloaded. Not all mobile apps offer push notifications, but the ones that do must understand the delicate balance. Many people uninstall mobile apps due to untimely push notifications that become annoying. Used properly, they are an excellent tool for businesses to communicate with their audience and spike engagement. Discuss why push notifications are essential to the success of a mobile app.

Rachelle's Answer #1

"Push notifications, used correctly, can keep an app alive and users continually engaged. For instance, a push notification should be used to remind the user of a flash sale or a new product release. Push notifications are known to increase engagement and sales greatly."

Rachelle's Answer #2

"Push notifications are what keep a mobile app user engaged and in-the-know when it comes to your business. The content needs to be to-the-point, and match the voice of your brand so that it resonates with your existing audience. The timing of push notifications is also crucial to the strategy. Most mobile users are active in the evening, so that's usually a good start to ensuring your push notifications are seen."

3.

In which mobile application testing tool are you best versed: Appium, Calabash, or MonkeyTalk?

Before you answer this question, it's a great idea to find out if WillowTree uses all three of these tools, or if they have a preference. If there is a preference for this role, focus your answer on what you know versus what you may not know. For instance, if you are stronger in Calabash, but WillowTree wants experience in Appium, let them know you have worked with both and then continue discussing what you know about Appium.

Rachelle's Answer #1

"I noticed in your job posting that you prefer candidates with experience in Appium. Although I have more experience testing mobile applications in Calabash and MonkeyTalk, I do consider myself to be an intermediate level user in Appium. I am very familiar with open source test automation frameworks for use with native, hybrid and mobile web apps."

Rachelle's Answer #2

"With about three years' experience in Appium, I would say this is my strongest area when it comes to mobile application testing tools. I have received training in Calabash and MoneyTalk, and am at a beginner level with those tools. If you feel that further training in these areas would be a significant help, I am happy to enroll in additional coursework right away."

4.

Name three ways a mobile app can make money. With which approaches are you most familiar?

When you can understand how companies best make money in the mobile app industry, it's much easier to develop apps that are responsive to that particular goal. The interviewer would like to see that you understand there are a variety of ways to earn money from a mobile app. If you have downloaded any of the apps created by WillowTree you should be able to identify which methods they rely on for making a profit, allowing you to bring that up in your discussion.

Some earning tactics are:

- Charge per copy
- Monthly subscription
- Ads and sponsorships
- Micro-transactions
- Premium Upgrades

Rachelle's Answer #1

"I have downloaded your most recent mobile app and saw that you use a blend of ads and micro-transactions to drive profits. This method is one that I appreciate the most because it gives people the option to use the free version, interrupted by ads, or a paid version should they prefer. I am also aware that monthly auto-subscriptions are very popular in the mobile app industry."

Rachelle's Answer #2

"The three methods which I am most aware and experienced in, include ads, monthly subscriptions, and charge per copy. As a mobile app developer, I am experienced creating apps around all three of these models; and as a frequent user of mobile apps, I prefer monthly subscriptions."

5.

What software development tools have you used?

There is a multitude of software development tools available, and they change all the time. The interviewer is looking for a better understanding of the tools that you use, and the development skills you will bring to this job. If WillowTree mentions any specifics, or preferences, when it comes to software development tools, this is a perfect time to indicate your level of experience with them.

Rachelle's Answer #1

"I see that you mentioned Atom and Cloud 9 in your job posting, both of which I have approximately three years' experience. I have also worked with Linx, although I am a beginner level in that particular tool."

Rachelle's Answer #2

"When it comes to software development tools, the bulk of my work has been with the NetBeans. I like this tool because it can be installed in many operating systems, making it an excellent option for projects of all kinds."

6.

What are the most important priorities for a social media manager?

Social media strategy is unique to each company and could change based on the needs of the company at the time. Hence, the interviewer wants to see if you thought about needs specific to WillowTree at this time and could define priorities accordingly.

Research the latest news about WillowTree (new product launch, any PR issues, etc.) and include them in your response.

Rachelle's Answer #1

"I would say priorities really depend on the company and what the company needs at the time. Social media manager needs to be able to roll with the punches and be agile. Since you're launching a new product line, I'd say creating campaigns to promote your new line and getting usable feedback would certainly be a priority. Also, since competition has been increasingly fierce, monitoring competitive intelligence and your position against its competitors would also be on the top of the list."

Rachelle's Answer #2

"Given the fast-paced environment of social media marketing, my focus will be on automating a lot of tasks so we can get our messaging out more quickly than our competitors. Also, I'd focus on finding meaningful insights real-time from social media engagements by leveraging and improving analytics tools."

7.

What makes Facebook or Instagram a great marketing tool?

The interviewer wants to see if you understand the capabilities provided by Facebook/Instagram to advertisers. You want to show them that you are not only aware of the offered/available analytics and capabilities but how they could be best leveraged by savvy advertisers.

Bonus points if you can mention other competitors in the market and compare the platforms.

Rachelle's Answer #1

"As a start, Facebook and Instagram boast large user base. I believe Facebook has over 2 billion active users and Instagram has 800 million. As a start that gives you a wide audience spread across the globe. The strength of Facebook and Instagram's ad analytics is that it gives you the ability to target customers much more accurately. You can target them based on location, gender, and other profile info. But more importantly, you can target people based on behaviors in a way that wasn't possible before - based on their preferences (their 'like' patterns), their network, activities, etc. They also are often able to track the customers' paths and behaviors even when they are outside the platforms, making their understanding of each customer's profile and preferences more accurate."

Rachelle's Answer #2

"While Facebook has very robust analytics and bigger base, it's important to caveat it with the fact that its fastest growing base is seniors where Twitter is mostly under 45. In addition, even though Twitter only allows for simple/concise micro-PR messages compared to Facebook where you can show more in-depth content, it's a lot easier to get followers on Twitter than it is to get likes on Facebook. So deciding which platforms to use depends on the specific campaign, target demographics, and messaging."

8.

Are you LEAN Six Sigma certified?

Lean Six Sigma is a methodology that teaches how to eliminate waste of all kinds, within an organization. The education certifies you as an expert on efficiencies in the workplace. When it comes to Six Sigma certifications, there are a variety of levels which you can obtain. You begin with white, and work your way up to yellow, green, and black, with the highest option being MBB (Masters' Black Belt). Share with the interviewer if you are Six Sigma certified. If you are, discuss how far you have taken your certification. If you do not have your certification, show enthusiasm for the idea and express that you are open to expanding your professional knowledge and training.

Rachelle's Answer #1

"I have looked into LEAN Six Sigma training and would be very interested in expanding my education to include this esteemed certification. There is a course beginning next month, and I am happy to register if you feel it would be the value added that WillowTree is looking for."

Rachelle's Answer #2

"I am currently earning my green belt in Six Sigma. My goal is to earn my MBB level certification within the next five years. I have learned a great deal about business process and streamlining. I fully believe that every person in the management consulting and implementations sector should become white belt certified, at the very least."

9.

What are the most common mistakes you see in mobile app development?

WillowTree seeks to hire only the best talent in mobile app development, and they want to see that you are aware of potential mishaps and that you take the necessary actions to avoid them. Some of the most common errors in mobile app development include:

- Lack of platform research, before beginning a project
- Approaching app monetization as an after-thought
- Forgetting about how to market the mobile app once it launches
- Beta-testing their own app, as opposing to hiring a third party

Assure the interviewer that you are aware of these common mistakes and that you know well enough to avoid them. If possible, give an example of a highly successful mobile app project you have recently completed.

Rachelle's Answer #1

"In my four years in the mobile app industry, I would say the most common errors I see include developers beta-testing their own work, and forgetting about monetization and marketing until it's too late. I fully believe that marketing and monetization need to be approached and planned out before development even begins."

Rachelle's Answer #2

"Having the right foundation is incredibly important before starting any mobile app development. One recurring error I see is developers choosing iOS over Android, or vice versa, out of complete bias versus genuine research. It's best to be critical of the platform options to support your app idea and then move forward with the project."

10.

What is social media marketing?

The interviewer will want to make sure you have a fundamental understanding of what social media marketing is before going forward with an interview at WillowTree. Put it in your own term - make sure to mention its relevance in today's commercial environment.

Rachelle's Answer

"Social media marketing is a practice of leveraging social media channels to reach out to and connect with potential customers and drive traffic to the brand. It allows corporations to insert itself in relevant dialogues on digital platforms where our target customers are active and raise awareness. In today's world where the intersection of physical and digital connections is getting rapidly wider and where people are inundated with waves of information all competing for their attention, being able to strategically create social-media appropriate content and place such content in the right places of those digital dialogues is a differentiator for companies."

11.

Which technical resources do you use to help you do your job?

The interviewer would like to know which tools and resources you look to when you need assistance in your job, or when you want to strengthen your skills or knowledge. If WillowTree mentions preferred tools in the job posting, or if they publish excellent resources of their own, be sure to mention them. The tools that you lean to could be blogs, apps, websites, or even subject matter experts.

Rachelle's Answer #1

"I enjoy keeping aware of the industry's best tools and resources. Before applying to work here, I was subscribed to the WillowTree blog, which I have always found very helpful. I also turn to resources such as my direct supervisor who is a wealth of technical knowledge. Lastly, I regularly visit TechCrunch online for tech news and the hottest updates."

Rachelle's Answer #2

"I graduated from Stanford and often use their online resources, available to alumni. I admire tech influencers such as Elon Musk and Dave Winer, who I follow on Twitter. Do you have any recommendations for must-have resources? I am always interested in gaining new tools."

12.

What is the highest ROI percentage you have delivered to a client?

An excellent consultant will know exactly what they have delivered to clients in the past, and why they were able to achieve such exceptional results. Talk to the interviewer about the greatest ROI you have been able to help a client achieve. Include your thoughts on what made the project a success and assure the interviewer that you will be able to repeat that success.

Rachelle's Answer #1

"The highest ROI I was able to deliver to a client was a whopping 62%. Our company's standard at that time was 26% so you can see my excitement when our team was able to generate such a great result. The client did not expect such a significant return, and I attribute the success to our highly collaborative approach, excellent communication, and an exceptionally talented team. I look forward to delivering similar results to WillowTree."

Rachelle's Answer #2

"Last year, my average ROI was 17%, with an industry average of 9%. I believe my success is directly related to the fact that I perform regular progress reports, ensuring my clients are fully aware of where the project is headed. Clear communication means a smoother project and top-notch results. I am excited to bring these same results to WillowTree and your clients."

13.

In which ways do you think AR and VR will impact mobile app design this year?

Augmented Reality (AR) and Virtual Reality (VR) are making a splash in the mobile app industry, and continue to grow in popularity. You may recall when PokemonGo was released. It was and continues to be, one of the biggest successes in the use of AR for mobile applications, to date. The interviewer would like to see that you have a solid understanding of where AR and VR will take the mobile app industry in the next 12 months.

Rachelle's Answer #1

"I believe that AR will surpass VR regarding mobile use, only because of its ease of use. Some excellent examples of augmented reality in mobile apps include 'Just a Line,' one of Google's AR experiments. I also enjoy Holo, which is an app that allows you to take characters from real and fictional worlds, and embed them into your photos. I believe that AR and VR will boost the creative abilities of the average person, significantly. We are going to see many more interactive games come to market as well, easily rivaling typical console game experiences."

Rachelle's Answer #2

"As a mobile app designer, I am thrilled to see what AR and VR will do in the coming months. One of the most interesting factors for me is the use of 3D recognition and mapping. For instance, in measurement apps. Thanks to AR's ability to know where 3D objects begin and end, we can measure distance, angles, volume, and surface area from our mobile devices. This AR allows VR to step in and help plan and design the perfect room or building structure."

14.

How would you improve the user experience (UX) of a mobile app without changing the interface?

The interviewer would like to see that you have helpful and thoughtful suggestions when it comes to making a mobile app more user-friendly, without completely reinventing the app. Some ways that a team can improve the UX of a mobile app without changing the interface include hiring a third party to fix usability errors that you may not see, removing unvalidated features, or learning to analyze user behavior and other analytics better. This question is open-ended to beware of falling down the rabbit hole. Give a couple of thoughtful ideas and briefly discuss if you have implemented those ideas in the past.

Rachelle's Answer #1

"There are quite a few ways that the UX can improve on a mobile app without drastic interface changes. In the past, I have worked to remove unvalidated features, which prevents the watering down of the application, thus offering only what the user wanted out of the app in the first place."

Rachelle's Answer #2

"When I need to improve the UX of a mobile app I will first take a look at negative user feedback. Often the feedback has to do with unwanted or unnecessary features being a distraction. Next, I look at the animation and see if there are ways of improving icons and other smaller yet important images. I will also check out the onboarding experience to see where it can be improved. Most UX issues can be easily fixed by absorbing feedback and carefully watching a handful of analytics."

15.

What do you believe is more important: the system being user friendly or comprehensive but complex?

Your interviewer is looking to see what you value when you're developing, modifying, or upgrading systems. Do research about WillowTree so you can also add details in your answer that are customized to what they're doing. In your answer, be sure to explain how you balance both in your work to ensure the end user has a good experience all around.

Rachelle's Answer #1

"I don't believe that you have to sacrifice either. I've worked very closely with UI/UX teams to ensure we're developing a system that is functional and has a design that makes it easy for the end user to perform their tasks. In my last role, we were adding a module to the existing system. Our team worked closely with UI/UX to ensure the new time tracking system was easy to use and had the technical functionality to prevent errors. The importance of time tracking made it even more critical that we were balancing functionality with design to help prevent user error."

Rachelle's Answer #2

"When I'm working on a project, whether that is a new system overall, an upgrade, or modifications, I am heavily focused on its comprehensive functionality, but I also partner with UI/UX to ensure we're creating a well-rounded product that will have significant benefits for the client. As a technical specialist, I am more focused on the comprehensive functionality of the system, but I never neglect the design and that's why I feel it's so important to have a relationship with UI/UX. We implemented a new benefits module in my last role and through my effective relationship with UI/UX, we were able to create a user-friendly, comprehensive interface while still coming in under budget and on time."
