How our iOS online tests and coding questions work

DevSkiller iOS online tests and coding questions work by giving developers challenges that actually reflect their work. DevSkiller uses the RealLifeTesting™ methodology, which allows your business to accurately test a developer candidate’s iOS skills within a controlled environment.  Each iOS test is designed to mirror the real-life scenarios that developers would face in their real working day, offering you a unique insight as to how successfully a candidate will be able to operate within your business.

Caractéristiques principales

  • DevSkiller iOS online tests provide a clear insight into your applicants’ coding skills and not just their academic knowledge.
  • Remote testing saves you time and money.
  • La méthodologie RealLifeTesting™ offre une plus grande expérience utilisateur où les candidats peuvent utiliser leur propre IDE, cloner sur GIT, exécuter des tests unitaires et accéder à Stack Overflow/Github/Google pour la recherche.
  • Anti-plagiarism tools to ensure accurate test results
  • Observer les tests individuels en temps réel
  • Des résultats automatisés compréhensibles par des professionnels non techniques
  • iOS tests available for all levels of experience

What to look for in an iOS developer

iOS is the operating system developed by Apple originally to power its iPhones, but since then iOS has been installed into Apple’s other devices including the iPad, Apple Watch, and Apple TV.

There are two languages that have been developed for use with iOS, Objective-C, and Swift. Your future iOS developer needs to demonstrate their prowess in at least one of these. Swift is the younger of the two and has become the language of choice for most iOS developers due to the fact that it borrows from other programming languages including Objective-C and JavaScript, making it more convenient to use. Experience working in other programming languages such as C++ is also going to come in useful.

iOS changes quite frequently, with major updates being released every year, so a good iOS developer will need to be someone who stays in touch with the latest advances in iOS technology. Experience working with iOS technology on specific platforms such as Apple Watch or Apple TV is also going to be very helpful.

In addition, there are two very important libraries that iOS developers must know well, UIKit and Foundation. These libraries are essential for any iOS developer to be able to build apps. There are also a huge number of open-source libraries and frameworks that iOS developers can draw on to build their software so knowledge of these is required.

It will also be very useful if an iOS developer candidate has previously worked on projects that have seen them, not only developing apps, but also working with essential functions like Bluetooth, local databases, and working with location services.

Build your own custom iOS online tests and coding questions

If you would like to customize your iOS online tests then this can be easily done. The DevSkiller online task wizard has been pre-set with many features that allow you to customize your test invites at every level. You can set the languages you want to test, as well as the duration of each test and you can monitor an applicant’s test in real-time. Remote testing also allows you to seek out the best iOS developer from anywhere.

Still unsure about our iOS online tests?

If you think DevSkiller iOS tests are what your business needs, but are still unsure, check out the following case study:

Plutora est un leader du marché de la gestion du flux de valeur, avec des solutions de mise en production, d'environnement de test et d'analyse pour l'informatique d'entreprise.

Before turning to DevSkiller in 2018, Plutora used to screen candidates, using a three-step interview process. Firstly there was a phone interview, followed by a technical interview and finally a behavioral interview. This recruitment method was not only time consuming, but it also required a lot of work on the part of Plutora’s employees. Furthermore, the phone interviews didn’t eliminate the candidates who didn’t have the skills needed, meaning more interviews happened at the later stages,  in order to filter out the right candidates.

In 2018, Plutora enlisted DevSkiller’s help with the aim being to automate the screening process to make less work for employees and cut down on the number of interviews being conducted, while also filtering out those who don’t possess the required skills, before the interview stage.

Not only is the system now automated, but thanks to DevSkiller, Plutora now saves approximately 8 hours of internal developer time per candidate, because internal developers are no longer needed to assess which candidate has the required skill set, as DevSkiller does this for them.

Richard Williams- Vice-président de l'ingénierie chez Plutora

"Grâce à l'automatisation de la phase de sélection, nous avons pu réduire le taux d'entretien de 50%. Dans le même temps, la qualité des candidats qui parviennent à l'étape de l'entretien est désormais bien meilleure. DevSkiller ajoute un niveau de qualité supplémentaire à notre processus d'embauche technique"

Questions fréquemment posées

How are iOS online tests and coding questions evaluated?

One of the main benefits of the DevSkiller platform is that iOS tests can be evaluated automatically. Once a test is completed, the platform automatically gets to work on providing the results. This means that tests can be taken, but also evaluated at any time of day, making the whole process extremely time-efficient. The results are then organized into a report that even the most non-technically minded recruiter will be able to understand.

Candidates are assessed in many areas, including whether the solutions they have provided would work and the quality of their coding.

How do candidates undertake an iOS online test?

DevSkiller’s iOS online tests and coding questions are accessed by the candidate remotely, meaning they can be taken from anywhere and at a time that is convenient to the candidate. All you, the recruiter would need to provide is a link to the test. If you require the test to be completed within a specific time-frame, you can then set the link to be active for only the allotted amount of time. You can also set how long each test will last for and if the candidate runs out of time, the test is automatically sent for assessment.

To take the test, candidates have the option to use our state of the art in-browser IDE or to complete the project on their favorite IDE and then clone the project to GIT. To monitor their progress during the tests, candidates can also run unit tests to check that their solutions work.
