For this, app developers need to invest years learning the best practices of interface development to ensure users get an easy and smooth experience when using it. Judging creativity can be subjective but the frequency of innovations can be quantified. Try to know about past experience in developing intuitive UIs when looking for in-office or remote app developers.

2. Knowledge of cross-platform development

This systematic approach is termed as Agile methodology based on different iterative and standalone processes.

Projects may vary on client-specific requirements, local laws, and also development procedures. While development procedures and functional requirements can be tweaked to find the best fit, app developers need to stick to stipulated legalities. For which, developers with previous experience in deploying security protocols will be a better fit for organizations. So, if you need to hire app developers for your organization, try to find professional developers familiar with working with security guidelines.

5. Expertise in multiple languages

There are several programming languages that can be used to develop mobile applications and PWAs. Each has its own advantages and limitations for which knowledge of a wide variety of programming languages is essential to achieve goals and objectives.

Here’s a small list of languages you can refer to for reference.

  • Java
  • Kotlin
  • C#
  • Swift and more

6. Good communication skills

Hiring the right app developers is not just about finding people with the right knowledge. Rather, the point is to find professionals who can join the team and start contributing immediately with confidence. For which, in today’s world interpersonal skills are as important as possessing the necessary technical skills. Especially if a company operates remotely with teams spread out across the world. Try to hire app developers who can take part in brainstorming sessions and provide valuable inputs.

Create a hiring funnel

Hiring for technical profiles can be a tough job, especially if you’re hiring for new roles. To make the process simpler and make sure to hire app developers who fit your team working with a hiring funnel is the best approach.

Top 10 questions to test knowledge of App Developers

The importance of finding a talent who can drive and own entire projects with confidence can be a complex task. But asking the right questions can help to make the process a lot simpler. Here’s a list of questions that you can use to hire app developers that you can rely upon.

This question can be used to understand if the app developer has spent time studying the offer at hand. Try to see what kind of suggestions he/she provides to help attain business goals.

Singleton pattern is a type of creational pattern which helps to integrate single classes to create objects. These types of classes allow direct access to objects without instantiating object classes. Experienced and knowledgeable developers should face no problem answering such questions and provide a prompt answer.

If you’re looking to hire app developers for deploying on projects for Android devices, look for people with clear knowledge of development processes. See if the developer is able to mention all four application components - Activities, Services, Broadcast Receivers, and Content Providers.

Builder patterns are used for building complex objects using simpler objects following a step-by-step approach. Developers with deep development experience should not face trouble answering builder pattern-based questions.

Xamarin offers three different options for sharing codes between cross-platform applications namely - .NET Standard Libraries, Shared Projects, and Portable Class Libraries. Any app developer with a few years of experience should be able to answer these questions.

This question can be used to understand the developer’s level of understanding about security concerns related to Ionic apps.

If the value type structs are immutable, it means other variables are not allowed to alter values for instances of structure at any given point. A mutating word will be required to change values of self variables only inside the structure's functions.

In Swift, as? Is explicitly used for upcasting or pattern matching. While 'as!' produces an optional value, 'as' doesn't provide an optional value. Try to hire app developers who can effortlessly explain simple concepts with perfection and details.

Using Xamarin Forms, not only is it possible to share the business logic, but also the UI. But with Xamarin Native developers can create a UI per platform and a lot more thanks to its native components.

You can use this question to test an app developer’s understanding of hybrid applications and their advantages. See if he/she lists advantages like:

  • Multi-platform compatibility
  • Unified development.
  • Faster and cost-efficient development
  • Easy to update and upgrade
