As more and more businesses are moving their services to the cloud and creating mobile apps, it’s no surprise that many companies are looking to hire developers who can create great products. And while you might be a rock star at developing web applications or desktop software programs, your ability to build an app that works on a smartphone or tablet is what separates you from other candidates. So if you’re one of those would-be developers looking for ways to stand out in today’s job market, here’s a friendly guide on what it takes to land your first interview with a potential employer:
What kind of mobile apps have you built?
The interviewer will want to know what kind of apps you’ve built, and how they compare to the position you’re interviewing for. You should be able to talk about at least three different mobile apps that you contributed to building.
The interviewer will also want an idea of how big these projects were, so be sure to mention any teams that worked on each project with you (or even just one other person). If there were multiple people involved in creating an app, then explain who else was working on it with you and what their roles were–for example, “The team consisted of myself as well as three other developers.”
Can you tell me about your experience with object-oriented programming in Swift?
The interviewer is looking to see if you know what classes, protocols and structures are. They also want to make sure that you understand how to use them. Some of the questions they might ask you include:
Do you have any experience building iOS applications with Core Data?
What is your preferred development environment (or IDE) for building mobile applications?
The preferred development environment (or IDE) for building mobile applications is a tool that developers use to write code. A wide variety of IDEs and other tools are available, including:
How would you architect a distributed system?
A distributed system is a system that is made up of multiple computers that communicate with each other. Examples of distributed systems include the internet, mobile applications, and chat apps.
The main challenges of designing a distributed system are:
Tell me about your experience with MVC architecture.
MVC stands for Model-View-Controller. It’s a popular architecture that you’ll find in many applications, including mobile apps. In MVC, you separate the application into three parts:
How would you test a mobile application without a real device?
The first thing you need to do is decide whether you want to test the app on a real device or in an emulator. If there are any bugs that are specific to the hardware or operating system (OS), then it’s best if you can test it on a real device. However, most issues will occur at the software level and can be replicated using emulators.
If you don’t have access to either of these options, then cloud services like Firebase Test Lab and Google Cloud Functions could help simulate some of their functionality remotely so that they appear as if they were installed locally on your computer or smartphone.
What tool could I use to inspect my running app on an iOS device?
You can use the inspector tool to inspect your running app on an iOS device. The inspector allows you to view information about elements in your application, such as views and controls.
The debugger is also useful when working with apps on iOS devices. It allows you to pause execution at any point and step through code while watching its behavior; this makes debugging much easier than it would otherwise be if you were forced to guess where errors were occurring based only on their symptoms.
What are some standard ways of doing front-end development for an Android application?
The mobile app development lifecycle is made up of many tasks, including front-end development. Front-end developers are those who create or manage the user interface, which includes designing and building interfaces for apps. They also work on back-end systems like databases, web servers, etc., that power an application’s functionality. If you’re looking for a job as an Android developer (or want to become one), it helps to understand some standard ways in which people do front-end development for Android applications:
