Proficiency of C# and ASP.NET
C# is the familiar language applied on Xamarin to make iOS, Android and Windows applications. Therefore, it goes without telling that the formal Xamarin developer has strong proficiency in C#. You can customize your interview interrogatives that calculate the applicant’s knowledge and skills in C#.
Also, you can screen appliers with a logical background in .NET specific approaches similar as C# classes, lambda expressions, Async/ Await, and others. Cross-platform app development architectures are predicated on the Model-View-View Model (MVVM), a software design figure that’s applied to break agendas and arrange codes into modules to produce development, reuse and updates of codes speedily and better. Your Xamarin developer should possess a coherent control on MVVM.
Understanding Xamarin Studio and Visual Studio
The conceptual candidate should retain a profound understanding and mastery in development, deployment and debugging through Visual Studio. Xamarin is a tool that helps developers produce mobile apps through Visual Studio, a Microsoft- integrated development atmosphere required to make graphical user interfaces (GUIs), consoles, web apps, and web services.
Knowledge of Code Reusability
Xamarin developers must possess very good knowledge of code reusability. Check whether the developer knows how to retain sets of codes on distinct platforms, once the coding is run on one platform. The substantial products that developers apply to set up apps are Xamarin.Android, Xamarin.iOS, and Xamarin.Mac.
Along with this, the Xamarin developers must know cross platform code integrity that helps in reusability of the code.
Excellent understanding API & Third- Party Libraries
Rising quick-deployment needs during the development phase, knowledge about API and third party libraries is important while hiring Xamarin developer. Xamarin provides a wide range of reinforcement to APIs and third- party libraries. You can impose an applicant’s background in this field with the former projects that they’ve worked on.
Knowledge of SQLite database
SQLite is a popular database software library used for Xamarin which provides a relational database management system for data storage. Xamarin provides many packages to work with the database which gives permission update the existing SQLite database. The developer should have knowledge about how to access and manipulate SQLite database.
Experience with web markup and UI, UX Concepts
The developer must have a firm understanding of element positioning, displaying the elements, and making components interactive, semantic markup, and other related UX Concepts so they can design the product with the best quality. The developer must be experienced in developing visual effects in presentational markup. For, example – How the heading appears, making text larger and putting weight to it, and giving which color to it, and which markup can include captions, bind columns, and row headings to table cells.
Ability to cross browser compatible code
You must hire the Xamarin developers based on their ability to write cross browser platform compatible code. With cross-browser compatibility, your website will have an increasing traffic and it will deliver the best user driven experience, independent of the browser on which it is running on.
Proficient in writing optimized and readable code
To streamline the development process, the Xamarin developers must be proficient writing clean and high-performance optimized code that is understandable by all the team members.

Top Interview Questions to ask while hiring a Xamarin developer
Xamarin is a company that builds the software. The main operation of Xamarin is to build mobile apps that work on cross-platforms. It is used to build the UI for Android, iOS, and Windows operating system.
Xamarin has two approaches for app development.
Xamarin.Forms: Forms are the choices for the developers who want to create one application for all the separate mobile platforms, which are Windows, iOS, and Android.
Xamarin Native: This approach is used in those scenarios when we want to create a separate version of the same App for different platforms. Developers can use Xamarin.iOS, Xamarin.Android and Xamarin.Windows libraries to create the applications for each particular platform.
XAML or Extensible Markup Language is a special tool that allows the developer to define the user interface in Xamarin app development. XAML has a vital role in Xamarin, but it is not necessary for app development in Xamarin.Forms. Xaml works with ModelView-ViewModel or MVVM architecture of an application.
Xamarin Studio works on both Windows OS X environments while Visual Studio is available only for the windows environment.
Xamarin Studio on Windows supports only Xamarin.Android project. Visual Studio supports Xamarin.Android, Xamarin.iOS, and Xamarin.Windows project.
The major difference between them is how they layout the items.
ListView: ListView control displays the stacks of data vertically. It is just like a standard Listbox. We use this control to display the order of data in the list, especially the long list, that requires scrolling, like a list of email messages, a list of contacts, or search results.
TableView: TableView displays the stacks of data horizontally in rows. We use this control when we need more space for rich visualization of the item to be displayed.
The different types of pages present in the Xamarin.Forms are:
Content page- This type of page displays a single view, often a container such as a stack layout or the scroll view.
MasterDetail page- MasterDetailPage is a page that manages the information between the two related pages.
Navigation Page- Navigation page manages the navigation of the pages.
Tabbed Page- Tabbed Page helps the navigation of the children page using the tab.
Template Page- The Template page helps to display the content of the full page with a control template.
Carousal Page- This page allows the swipe gesture between the subpages, such as a gallery.
The different types of apps which use the Xamarin are:
OLO- an online platform to order food.
The World Bank survey app- This App is used for the global survey.
Storyo- This App helps to create videos from the picture.
Freshdirect- This App is our friendly grocer.
App.cs is the main class of the App which offers features like:
MainPage: It helps us to set the initial page of the App.
Properties Dictionary: It helps us to store the values across the state of the lifecycle.
Static Current Property: It gives the instance of the current application object
