A Xamarin developer must have a strong understanding of mobile development principles, including UI design, data handling, user input handling, and device features such as GPS and notifications.

7. Knowledge of XAML

Xamarin developers should have experience working with Extensible Application Markup Language (XAML) for designing UIs in Xamarin.Forms.

8. Familiarity with APIs and Web Services

Developers will often need to work with RESTful APIs and web services for data fetching and integration, cross-platform functionality, integration with cloud-based services, and service-oriented architecture.

9. Testing and Debugging

Any Xamarin developer requires experience in unit testing, UI testing, and debugging. These practices are essential for ensuring the quality and functionality of the application.

10. App Store Deployment

The Apple App Store and Google Play Store each have their own set of requirements and regulations respectively concerning app publication. Xamarin developers need to have knowledge of these rules when developing apps.

Soft Skills to Look for in Your Ideal Xamarin Developer

11. Communication Skills

Communication is essential in the development environment. Xamarin developers must communicate with team members, stakeholders, and clients.

12. Problem-Solving

Problem-solving skills allow developers to find innovative solutions to challenging problems and complexities in the development process.

13. Time Management

Xamarin developers juggle numerous responsibilities simultaneously. Time management skills allow them to effectively manage priorities, tasks, and deadlines.

14. Attention to Detail

Strong attention to detail is important for the accuracy and completeness of work.

By now, you should have a basic understanding of the technical and soft skills to look for in an experienced Xamarin developer. Next, let’s look at a few sample technical interview questions you can ask to separate the wheat from the chaff.

8 Questions to Identify Top Xamarin Developers

When interviewing Xamarin developers, it's important to ask questions that first assess the candidates' technical skills and knowledge. Employers will also usually conduct a coding test to further assess specific on-the-job knowledge.

The following set of questions aim to uncover not only the developer's technical knowledge but also their problem-solving abilities, teamwork, communication skills, and adaptability—all crucial traits for success in a collaborative environment.

Here are a few examples of technical interview questions:

1. What's the difference between Xamarin.Forms and Xamarin Native?

Sample Answer

Xamarin.Forms and Xamarin Native are both part of the Xamarin framework and are used for cross-platform mobile app development. However, they are used for different purposes. Xamarin.Forms is a UI toolkit that allows developers to create UIs that can be shared across iOS, Android, and Windows with a single codebase. Xamarin Native allows developers to write platform-specific code with C#.

2. Please give some examples of C# features that are particularly useful in Xamarin app development.

Sample Answer

C# includes a wide range of features that facilitate easier and more effective Xamarin app development. They improve code efficiency, enhance the developer experience, and help create robust and maintainable applications. These features include 

  • Language Integrated Query (LINQ) is used for data manipulation, particularly when you're working with collections or local databases, such as SQLite.
  • Asynchronous programming is essential for UI responsiveness in mobile applications.
  • Lambda expressions and delegates help create concise and readable code. They are particularly useful in event handling and LINQ queries, allowing developers to write less wordy code for callbacks and event listeners.
  • Extension methods allow developers to add additional methods to existing types without altering their source code. They're especially useful when you're working with custom controls or specific data types.
  • Partial classes and methods enable splitting the implementation of a class or method across multiple source files. This is helpful for separating the shared code from platform-specific code in large projects.
  • Generics improve code reusability and type safety, which is important for building reusable components and services in data models, view models, and service layers.
  • Nullable types offer a straightforward way to handle null references, which improves the reliability of the app.
  • Attributes can be leveraged to add metadata to code, accessed at runtime using reflection.
  • Properties and auto-properties provide a flexible way to expose private fields with getters and setters, simplifying property declaration and making code cleaner.

3. How do you ensure a consistent user experience across different platforms using Xamarin?

Sample Answer

I utilize Xamarin.Forms for UI design to ensure a consistent user experience across different platforms in Xamarin. I also implement a consistent design language and UI language and employ data binding and the MVVM pattern to maintain a clean separation of business logic from UI. Finally, I use Xamarin.Essentials to leverage common device functionalities in a consistent way across multiple platforms.

4. Can you explain the Model-View-ViewModel (MVVM) pattern and its advantages in Xamarin development?

Sample Answer

The MVVM pattern is a design approach that enhances the separation of concerns in app development. In Xamarin, it's especially useful for building maintainable, testable, and scalable apps, dividing the applications into the Model, View, and ViewModel.
