The Role of AI in Technical Assessments

AI systems are playing an increasingly important role in the hiring and recruiting process. Within the technology sector, technical assessments are one area of interest: these complex assessments aren’t easy to evaluate, requiring time and expertise that often just isn’t available.

Here’s what to know about what AI can — and can’t — do in the area of technical assessments.

What Are Technical Assessments?

Technical assessments are tools for evaluating an applicant’s technical abilities in one or more specialized areas. They are common in IT hiring and recruiting, where the specific abilities a candidate needs can’t be demonstrated on a typical resume.

For example, a candidate can state truthfully on a resume stating they have a background in machine learning (ML) or DevSecOps. But that background may not include every single specific skill, code language, and process the candidate knows, and it can’t show recruiters whether the candidate can solve the sorts of problems the hiring business needs solved.

A technical assessment asks the candidate to show their work, solving some example problem or writing some bit of code or in some other way demonstrating their skills in a scenario that mirrors the real world.

A Powerful Tool with Practical Weaknesses

It’s no surprise that technical assessments are used widely in IT hiring, especially for niche, advanced, and highly specialized roles. But as powerful as it is, this tool has numerous practical weaknesses.

1. They have to be built

First, someone has to design and build the technical assessments.

That can be a problem when organizations are hiring for specialties they don’t have or are short in. It’s possible to procure technical assessments from vendors, of course, but will these be targeted enough for the subspecialties the business needs? Can businesses modify them as needed to suit their specific workflows?

2. Someone has to interpret the results

A related issue here is that someone has to grade the assessments or interpret the results. This can be a particularly frustrating problem in the midst of a painful hiring crunch with no signs of easing: the US Bureau of Labor Statistics estimates the hiring gap will grow through at least 2029, reaching 1.2 million open IT jobs in the US by that year.

The more specialized or niche the role, the more likely this problem is.

Hiring managers often hire for skills they don’t themselves possess. Certainly generalist HR staff can’t be much use here, either. And even when a company has an existing employee with the relevant skill set, that person could be conflicted out of a sense of self-preservation (not wanting to endorse a candidate who’s better than them).

3. The system doesn’t scale well

The third issue with technical assessments is scalability. For an assessment to be graded automatically using legacy tech (think multiple choice), it has to be rigid and simplistic to a degree that could make the entire exercise border on useless.

But a completely open-ended technical assessment (“build us an app from scratch…”) is a scalability nightmare: scrutinizing every piece of a deliverable from every single candidate is time organizations and hiring managers don’t have.

AI’s Role in Technical Assessments

Using AI in hiring more broadly isn’t exactly new: many applicant tracking systems (ATS) use at least a basic level of AI to screen candidates, though these tend to be less intelligent keyword screeners in practical terms. Systems that follow a cut score, automatically rejecting candidates below a certain score and forwarding those above the cut score onward in the process, are also using rudimentary AI and RPA to function.

But given the limitations described above and the rapid advancement of AI systems, including natural language processing (NLP) and generative AI (GenAI) technologies, many companies are eager to turn to AI for more robust help, such as assisting in vetting candidates by evaluating the results of their technical assessments.

While they can’t replace the human touch necessary for successful recruitment, a new generation of AI tools are delivering results here, significantly enhancing the efficiency and accuracy of technical assessments.

How AI Can Help

The ways AI systems can help (and the limitations of those systems) are as varied as the systems themselves. But a few general trends, both positive and negative, are emerging.

Here are some of the most important ways AI can improve the technical assessment process.

1. AI tools are efficient and scalable

Depending on the complexity of the technical assessment, your human hiring manager or recruiter could be spending serious time on each one. (And that’s assuming you have someone with the skills to do that evaluation.)

AI tools can crank through these evaluations in practically no time, which greatly increases efficiency. An AI system can also run these evaluations practically simultaneously, whereas human staff can only do so one at a time. So relying on an AI system here is almost endlessly scalable as well.

2. AI tools are generally accurate, with certain caveats
Across the board, accuracy rates are high for AI systems that are well built. These systems excel at working out complex calculations and understanding complex inputs. And for certain types of evaluations, AI tools will be more accurate than humans (in a fraction of the time).

There are some caveats here: systems are only as good as the data that feeds them, so not every AI performs equally. And because of the way AI systems interact with data and queries, they do sometimes respond in surprising ways. (More on this when we discuss limitations below.)

3. AI can lessen the impact of a skills gap

AI can do a lot to level the playing field, enhancing the work of those with a lower skill level. So where there are skills gaps within hiring, AI can help reduce the impact. Though there will still be other hurdles to clear, a hiring manager who doesn’t have training in a particular niche can benefit immensely from an AI-graded technical assessment.

By providing a near-instant understanding of a candidate’s basic technical competence, these AI tools give nontechnical decision-makers key data that helps to inform hiring decisions.

4. AI can promote inclusion and reduce bias

Organizations striving to reduce bias and increase equality and diversity can benefit from AI tools evaluating technical assessments. A human recruiter will quickly pick up on natural language variances and candidate names as elements suggesting national origin or primary language. This can introduce bias, even on an unconscious level.

Properly designed, AI tools can ignore these variances or even obscure them from human decision-makers (such as by assigning candidates numbers rather than names). By focusing on the results of the technical assessment, not ancillary details, AI systems can reveal the best-qualified candidates without assumption or presumption.

Limitations of AI

AI has plenty of promise in this area, but recruiters should be aware of its limitations.

1. AI tools don’t operate like humans do

Once again at the risk of stating the obvious: AIs aren’t people.

That is to say, AI tools may not evaluate a technical assessment in exactly the same way a human would. It’s possible for an AI to miss the very obvious forest for the trees, so to speak. If a candidate solves a problem in a novel or unorthodox way, a human recruiter might consider that a sign of creativity and potential. An AI system might interpret the results as a failure.

Of course, this one goes both ways: AIs are regularly finding new and novel solutions to problems, so it’s feasible that one might approve of an unorthodox solution a human reviewer rejects.

The mistake is to feed an AI a set of instructions and assume it will respond exactly how a human would. A level of human oversight is still required to ensure common sense prevails.

2. AI tools can also increase bias

While AI tools can be used to decrease active human bias and discrimination, there’s always risk in any data-fed system. We’ve seen evidences of data-fed bias numerous times in facial recognition systems and even in consumer-facing chatbots. It all comes down to the quality of data feeding into the models and datasets powering the AI.

If the data is lopsided (such as in the case of facial recognition systems trained on disproportionately white images) or contains already biased information (such as has unavoidably happened with large language model genAI), then the resultant outcomes from the AI will likely demonstrate bias as well.

3. AI tools can bridge a talent gap but can’t close it

Last, while AI tools can help to bridge a talent gap, they can’t close it completely. That manager hiring for a skill set she doesn’t possess can be greatly aided by AI-powered technical assessments, but blindly trusting the results (and ignoring nontechnical elements, like soft skills) could lead to disastrous hiring decisions.

Leverage AI + Human Recruiters with Pumex

Ultimately, AI can significantly improve both the efficiency and accuracy of technical assessments as a hiring tool in IT — but it can never fully replace the human touch essential for successful recruiting and hiring.

That’s true even of our own in-house AI technical assessment tool: we believe it’s an industry leader, and we trust it. Just not blindly. We combine the best of what powerful AI systems can do with the ingenuity and humanness of top-tier professional recruiters to create a tech recruiting powerhouse that delivers results.

Introduction to Hybrid Apps

1. What is hybrid app development?

Hybrid app development is a process in which applications are built using web technologies like HTML, CSS, and JavaScript, then wrapped in a native container that allows them to function on multiple platforms, such as iOS and Android, from a single codebase. This approach enables the apps to use features from both native systems and web-based technologies. 

The main advantage is cost-effectiveness and ease of development, as it reduces the need to write separate code for each platform. However, these apps might not offer the same level of performance or integration with device-specific features as fully native apps.

Are hybrid apps the same as cross-platform apps?

Yes, hybrid apps and cross-platform apps are often used interchangeably, but they are not exactly the same. Hybrid apps typically refer to applications that are developed using web technologies like HTML, CSS, and JavaScript, and then wrapped within a native container that allows them to be deployed across multiple platforms. These apps can access device features through plugins or APIs.

On the other hand, cross-platform apps encompass a broader category that includes both hybrid apps and apps developed using other cross-platform frameworks or technologies like Xamarin, React Native, or Flutter. While hybrid apps are a type of cross-platform app, not all cross-platform apps are necessarily hybrid. Cross-platform development aims to create applications that can run on different operating systems with minimal code changes or adaptations.

2. What is the difference between a mobile app and a hybrid app?

The key difference lies in their development approach and how they interact with the device:

Mobile App (Native App)

A mobile app, often referred to as a native app, is developed specifically for a particular platform (iOS or Android) using platform-specific programming languages like Swift for iOS and Kotlin or Java for Android. Native apps have direct access to the device’s hardware (like GPS, camera, and microphone), resulting in better performance and a consistent user experience with the operating system. 

They tend to be faster and more responsive, providing a more seamless integration with the device’s features and capabilities.

Hybrid App

A hybrid app is a mix of a web app and a native app. They are built using web technologies (HTML, CSS, and JavaScript) and then wrapped in a native container using frameworks like Cordova or Ionic. This approach allows the app to be used on multiple platforms while sharing the same codebase. 

Hybrid apps can access some of the native features of the device, but they may not offer the same level of performance or smooth integration as native apps. They are generally easier and faster to develop for multiple platforms, but this can come at the cost of user experience and speed.

3. How do I start hybrid app development?

Beginning hybrid app development involves several key steps. 

Here’s a general guideline:

  • Define Your App Idea: Clearly outline what your app will do, its target audience, and the core features it will include. This step is crucial for guiding the development process.
  • Choose the Right Framework: Select a hybrid app development framework that suits your needs. Popular options include React Native, Ionic, Flutter, and Xamarin. Each framework has its strengths, so choose one that aligns with your app’s requirements.
  • Set Up Your Development Environment: Install the necessary tools and software based on the chosen framework. This might include development environments, SDKs, and other tools specific to your framework.
  • Learn the Technologies: Familiarize yourself with the languages and technologies used in your chosen framework. For most hybrid frameworks, this will include HTML, CSS, JavaScript, and any specific framework syntax.
  • Design Your App: Plan and design your app’s user interface. Consider using prototyping tools to visualize the app layout and user flow.
  • Develop the App: Start coding your app. Hybrid apps are generally developed using a combination of web technologies and then wrapped in a native shell, allowing them to operate on different platforms.
  • Test Your App: Testing your app is important. Ensure your app works across different devices and platforms. This includes functional testing, performance testing, and user experience testing.
  • Prepare for Deployment: Ready your app for deployment. This involves setting up accounts on the App Store for iOS and Google Play for Android, meeting their guidelines, and preparing app store listings.
  • Launch and Maintain: Once launched, gather user feedback for improvements and update your app regularly to fix bugs, add new features, and stay current with the latest operating system versions and security standards.

For those new to hybrid app development, start with online courses or tutorials specific to your chosen framework and consider small-scale projects to build up practical experience. Hiring experienced developers or consulting with a development agency can also be a great way to ensure the success of more complex projects.

4. What is a hybrid app, for example?

A hybrid app is a type of mobile application that combines elements of both native apps and web applications. A classic example of a hybrid app is Instagram. Originally, Instagram used a hybrid approach where the app was developed using web technologies like HTML, CSS, and JavaScript and then wrapped in a native container. This allowed it to function across multiple platforms while maintaining a consistent user experience.

In a hybrid app like Instagram, users can download the app from app stores just like a native app, but much of its functionality is handled through web technologies. This approach enables faster development and easier maintenance across multiple platforms, as the app’s core is the same for all users, regardless of their device.

Other examples of hybrid apps include Twitter (now X) and Uber Eats. These apps leverage the hybrid model to combine the cross-platform flexibility of web development with the user experience benefits of native applications. They balance performance, platform-specific features, and the ease of development and updating that comes with web-based technologies.

5. What is a hybrid app, and how are they developed?

A hybrid app is a type of mobile application that combines elements of both native apps and web applications. It’s developed using web technologies like HTML, CSS, and JavaScript and then wrapped in a native container. This combination allows hybrid apps to use a single codebase to run on multiple platforms, such as iOS and Android, while still accessing some native platform features.

Here’s how they are developed:

  • Use of Web Technologies: Developers create the core of the application using web technologies. This is similar to building a website or a web application.
  • Wrapping with a Native Container: The web-based application is then embedded within a native container using platforms like Apache Cordova or Ionic. This container essentially works as a web browser without the browser UI, allowing the web app to run on a mobile device.
  • Access to Native Features: Using plugins provided by the native container platform, the hybrid app can access native device features like the camera, GPS, accelerometer, and more, which are not available to web apps.
  • Cross-Platform Compatibility: Since the app’s core is built with web technologies, it can run on any platform that supports web content, allowing the same app to work on iOS and Android with minimal changes.
  • Design and User Experience: Hybrid apps often use responsive design to ensure a consistent user experience across various devices and screen sizes. They may also include platform-specific tweaks to better align with the look and feel of each operating system.
  • Testing and Deployment: Hybrid apps are tested similarly to web apps but require testing on physical devices to ensure they interact correctly with each platform’s hardware and software. Once tested, the app is deployed to app stores like Google Play or Apple.

6. What is meant by native and hybrid apps?

Native apps and hybrid apps refer to two different approaches to mobile app development, each with its own methodologies, technologies, and use cases.

Native Apps

    • Definition: Native apps are developed specifically for a particular mobile operating system. They are written in platform-specific languages. For example, Swift or Objective-C is used for iOS apps, and Java or Kotlin is used for Android apps.
    • Characteristics: They are fully optimized for the platform they are developed for, offering high performance and a seamless user experience. Native apps can fully access all the device’s hardware features, like the camera, microphone, GPS, etc., and can utilize the device’s native UI components and gestures.
    • Use Cases: Best suited for applications that require high performance, intensive use of device capabilities, or a highly refined user experience. Examples include complex games, photo and video editing apps, or apps that require sophisticated data processing.

Hybrid Apps

This portability, a core feature of the language, allowed it to be used across various platforms, essentially making it one of the first programming languages to be truly cross-platform.

C’s development was closely tied to the development of the UNIX operating system, which was also designed to be portable and cross-platform. The ability of C to be compiled on different machines was revolutionary at the time and laid the foundation for many other programming languages that followed, emphasizing cross-platform capabilities.

16. Is Java actually cross-platform?

Yes, Java is considered a cross-platform language because of its unique approach to execution. When Java code is compiled, it’s turned into bytecode, which is run by the Java Virtual Machine (JVM). This JVM is what makes Java cross-platform – it’s available for various operating systems like Windows, macOS, and Linux.

As a result, Java programs can run on any system with a JVM, adhering to the philosophy of “Write Once, Run Anywhere.” This means the same Java application can work across different platforms without needing specific modifications for each one. However, additional work might be needed for full cross-platform compatibility if a Java application uses platform-specific features.

17. What language is best for hybrid apps?

The most commonly used languages for hybrid app development are HTML5, CSS3, and JavaScript. These are standard web technologies used to create web pages and are employed in hybrid app development to create applications that can run within a native container on a mobile device. This approach allows the apps to access device features like the camera and GPS and to be distributed through app stores.

HTML5 is used for structuring and presenting content, CSS3 for styling and layout, and JavaScript for interactivity and accessing native device functionality. Combined with frameworks like Apache Cordova (formerly PhoneGap) or Ionic, these languages enable developers to build hybrid apps operating across multiple platforms, including iOS and Android, from a single codebase.

The choice of these languages and frameworks makes hybrid app development accessible to a broader range of developers, especially those coming from a web development background, and simplifies the development process for applications that do not require complex native functionalities.

18. What is an example of a cross-platform mobile application?

An example of a cross-platform mobile application is Spotify. Spotify, a popular music streaming service, uses cross-platform development to provide its app on various platforms, including iOS and Android. By adopting a cross-platform approach, Spotify ensures a consistent user experience across different devices while simultaneously managing and updating its app for multiple platforms. This strategy allows them to reach a wide user base with varied device preferences, maintaining feature parity and a uniform look and feel across all these platforms.

19. Can I do C++ and Java together?

In the context of cross-platform development, using C++ and Java together is possible through various methods, such as integrating native C++ libraries into a Java application using Java Native Interface (JNI). This approach is often used in cross-platform projects where C++ is utilized for performance-intensive tasks and Java for platform-independent aspects.

20. What language is Flutter written in?

Flutter, a popular cross-platform development framework, is primarily written in the Dart programming language. Dart, developed by Google, is used to create the Flutter framework and is also the language developers use to build applications using Flutter. Dart was chosen for Flutter due to its efficient compilation of native code, its modern features conducive to reactive UI development, and its ability to support both front-end and back-end development, making it well-suited for the goals of the Flutter framework.

21. Is Kotlin a multiplatform?

Yes, Kotlin is a multiplatform language. Kotlin Multiplatform, a feature of Kotlin, allows developers to write code that can be shared across multiple platforms while still allowing for platform-specific implementations where necessary.

With Kotlin Multiplatform, you can write common logic once (like business logic, database access, and network calls) and then use it on various platforms such as iOS, Android, Web, and desktop applications. You can then write platform-specific code (like UI) for each platform to complement the shared code. This approach offers the efficiency of a shared codebase while still leveraging each platform’s unique features and capabilities.

Cross-Platform FAQ Series Part 1: Introduction to Cross-Platform Development

1. What is cross-platform development?

Cross-platform development is the process of creating software applications that are compatible with multiple operating systems and platforms, such as Windows, macOS, Linux, iOS, and Android. Instead of writing unique and different codes for each platform, developers use various tools and programming languages to write a single codebase that developers can use to run across different platforms.

This efficient approach saves time and resources, allowing for more accessible updates and maintenance. It’s particularly popular for mobile app development, where tools like React Native or Flutter enable developers to build mobile apps for both iOS and Android simultaneously. However, it’s important to balance this efficiency with the need to ensure that the app performs well and feels native on each platform.

For instance, languages like JavaScript, along with frameworks like React Native or Xamarin, enable developers to write code once and deploy it on both iOS and Android mobile platforms. Similarly, web technologies like HTML, CSS, and JavaScript can create applications that run uniformly on various web browsers across different operating systems.

2. What is the difference between platform and cross-platform?

The terms “platform” and “cross-platform” refer to different concepts in software development:


This refers to the operating system or environment where a software application runs. Common platforms include Windows, macOS, iOS, Android, and Linux. When developing software, programmers often need to consider the specific requirements and features of their target platform. For example, an app designed for iOS would be built using Swift or Objective-C and would follow Apple’s design guidelines.


This term is used when software is developed to work on multiple platforms rather than just one. Cross-platform development involves writing one codebase that can run for mobile apps on various operating systems, like iOS and Android. This is achieved using special tools and programming languages, such as React Native (uses JavaScript) or Flutter (uses Dart), which allow developers to write code once and deploy it across multiple platforms. The main advantage is efficiency: developers can reach users on different types of devices without having to write and maintain separate codes for each one.

3. What is hybrid and cross-platform?

Hybrid and cross-platform development are both methods used for creating software that can run on multiple operating systems, but they approach it differently.

Hybrid development typically involves building applications using web technologies like HTML, CSS, and JavaScript and wrapping them in a native container. This native container allows the app to be installed and used like a native app on various platforms, such as iOS and Android.

The main advantage of hybrid apps is their development efficiency, as the same web-based code can be used across different platforms. However, they might not provide the same performance or fully native look and feel as applications built specifically for each platform.

Cross-platform development, on the other hand, involves using specific frameworks like Flutter or React to build mobile apps that can run on multiple platforms but with a closer approach to native development compared to hybrid apps.

These frameworks allow developers to write code in languages like JavaScript (React Native) or Dart (Flutter), which is then compiled into a form that can run more natively on each platform. Cross-platform mobile apps offer better performance and a more native user experience than hybrid apps but with the advantage of a shared codebase across platforms.

4. What is cross-platform strategy?

A cross-platform strategy in software development involves designing and building software applications that work on multiple operating systems or platforms, such as Windows, macOS, iOS, and Android, using a single codebase. This strategy aims to maximize reach and efficiency by allowing the software to function across various devices and platforms without developing separate versions for each.

Key components of a cross-platform strategy include:

  • Choosing the Right Tools: Select frameworks and languages that support cross-platform compatibility, such as React Native, Flutter, or Xamarin.
  • Consistent User Experience: Ensuring that the app provides a consistent look and feel across different platforms while respecting each platform’s design norms and usability standards.
  • Code Reusability: Writing code that can be reused as much as possible across platforms, reducing the time and resources needed for development and maintenance.
  • Performance Optimization: Balancing the convenience of a unified codebase with the need for the app to perform well on all targeted platforms.
  • Testing and Quality Assurance: Rigorous testing on all platforms ensures the application performs reliably and as expected.

5. Why is cross-platform popular?

Cross-platform development is popular due to its several compelling advantages:

  1. Wider Reach: It enables apps to run on multiple platforms like iOS and Android from a single codebase, broadening the potential user base.
  2. Cost-Effective: Developing one app for all platforms can be more economical than creating separate native apps for each platform.
  3. Time Efficiency: It saves time in development and deployment as the same code is used for different platforms.
  4. Simplified Maintenance: Updating and maintaining a single application is often simpler and faster than managing multiple native apps.
  5. Resource Utilization: It allows businesses and developers to leverage existing skills and resources, as many cross-platform frameworks use popular programming languages like JavaScript.

6. What is the cross-platform language in 2024?
