How our Objective-C tests work

Devskiller’s Objective-C online tests for mobile app developers are powered by the RealLifeTesting™ methodology. In this model, the applicant is required to build a new app or add features onto an already existing piece of software using objective-C. 

This means that you’re able to test your developer’s skills in a real-life situation, away from your product and in a monitored environment. You’re able to not only test their coding skills but also their problem-solving abilities, creativity, and logic.

Key features

  • Test real-life coding skills, rather than academic achievements
  • A full-stack system means candidates can use all the resources that are on offer for the given role. 
  • Tests can be taken by any candidate, anywhere in the world, at any time. 
  • Durable and extensive plagiarism controls verify and ensure the quality of your candidate’s skills
  • Your candidate’s tests are automatically evaluated, sending your recruiters a non-technical report for them to then make further decisions
  • Available to test junior, middle, and senior Objective-C developers

What to look for in an Objective-C developer

Objective-C is a general-purpose programming language used to make mobile apps for iOS. 

When hiring an Objective-C developer, it’s important that you asses a candidate’s Objective-C skills, alongside their coding skills in other languages. Objective-C is often used in older apps, as most iOS apps are now coded in Swift. Therefore it’s crucial that you test a mobile app developer’s Objective-C skills alongside their Swift coding skills.
