How our iOS interview questions work

Drevet af RealLifeTestingTM methodology, DevSkiller iOS interview questions and online tests will help you find the most qualified iOS developers. Our online tests go further than assessing your candidate’s academic ability by placing them in real-world scenarios and asking them to build or add new features to an application using the different technologies of iOS. Test iOS developers in both Objective-C & Swift within a single test and determine their coding ability, business logic, and time-management.

  • Test af færdigheder inden for softwareudvikling og ikke kun akademisk viden
  • Praktisk fjerntest, der kan udføres hvor som helst og når som helst
  • RealLifeTestingTM methodology creates a better user experience and allows candidates to develop software, using their own IDE, clone to GIT, access Stack Overflow/Github/Google for research, and run unit tests.
  • Strenge værktøjer til bekæmpelse af plagiat, der sikrer testens nøjagtighed
  • Automated test results that non-technical recruiters can understand
  • Tests available for junior, middle and senior iOS developers

Hvad du skal kigge efter hos en iOS-udvikler

iOS is the operating system for most Apple products outside of their computers. Initially conceived to power the iPhone, Apple has used this operating system to power several other devices, including the iPad, Apple Watch, and Apple TV. When you talk about an iOS Developer, you’re actually talking about a developer who uses one or both languages, which are proprietary to iOS – Objective-C and Swift.

iOS developers who have experience in projects such as Bluetooth, local databases, and working with location services is a positive sign. Another huge plus is if they’ve developed an app that can be verified on the iOS app store. Experience in another programming language such as C++ is also a good sign. Finally, first-hand experience with a specific platform (e.g. Apple Watch) is an excellent indication of a qualified candidate.

Want proof that our iOS developer interview questions work?

It is understandable to be a little apprehensive when deciding whether to invest your company’s money in our screening tool. After all, DevSkiller testing is different from the conventional developer tests you might have encountered before. We’re so confident in our iOS developer interview questions, that we’re happy to let our past clients do the talking for us:

Ivana Nikolic - HR-chef hos ImpacTech

"Den største fordel for kandidaterne er, at de kan gennemføre prøverne, når det passer dem bedst. Hvis du har en kandidat, der allerede er i arbejde og overvejer at skifte karriere eller flytte til en anden virksomhed, er det også en tidsbesparelse for dem, da de ikke behøver at tage fri for at deltage i mange samtaler i jagten på en ny stilling."

Julien Gauthiez - Talent Acquisition Manager EMEA hos Criteo

"Vi bruger DevSkiller på 15 steder i vores tre regioner (USA/APAC/EMEA). Vi har 7 hyppige brugere i TA (rekrutteringsansvarlige) på tværs af vores regioner, og vores tekniske hiring manager-brugere skifter afhængigt af de aktuelle behov. Mere end 30 har logget ind på platformen en gang for at gennemgå en opgave eller oprette en test."

Olga Berger - Ledende rekrutteringsspecialist hos CodeValue

"DevSkiller er nem at bruge og venlig."

Ofte stillede spørgsmål

Hvad er RealLifeTestingTM?

If you’re wondering what makes DevSkiller testing so unique, it is that we implement the RealLifeTestingTM methodology into our iOS developer interview questions. RealLifeTestingTMworks on the premise that the best way to assess a developer’s skills is by recreating their work environment and setting them challenges based on that simulation. That’s exactly what RealLifeTestinTM is, a simulated version of a developer’s everyday reality.

Instead of asking developer candidates to recite coding patterns and algorithms that they might not have used in years, we ask them to simply carry out the kind of work they are used to doing and will be doing in the role and then assess them based on their actual development skills. It sounds like it should be an obvious way to test developers, but up until now, this hasn’t been the case.

DevSkiller iOS developer interview questions offer recruiters a comprehensive understanding of an applicant’s skill level. The successful candidates are those who demonstrate a clear understanding of iOS, who best utilize resources like Stack Overflow, and who possess the critical thinking skills required to deal with the challenges faced

Skal jeg være programmør for at bruge DevSkiller?

We don’t expect you to be an expert in iOS, we have our own experts for that. Our developers have made our iOS developer interview questions as simple and as automated as possible to take the pressure off recruiters. This means you don’t have to be an expert iOS developer to be able to hire one. Our tests accurately verify the technical skills of the candidates screened on your behalf. Not only that, but the assessment is automatic meaning once a test is completed, an automated, non-technical report is produced to let you know how well the candidate has performed.

Hvordan tager ansøgerne en prøve?

In-house testing can be time-consuming. The great thing about DevSkiller iOS developer interview questions is that they can be accessed remotely. Send out a test invite to your developer candidates wherever they may be and they can take the test and send it back to you. This means that the candidates can take the tests whenever is convenient for them and automatic evaluation makes it convenient for you too. Time-limits for how long a test link is active can even be set to make sure you’re not left waiting around for the results.

When it comes to taking our iOS developer interview questions, candidates have the option to use our own state of the art in-browser IDE, or if they would rather, they can complete the project on their favorite IDE and then clone the project to GIT afterward. Much like with their real development work, candidates can run unit tests to ensure their solutions are working the way they’re supposed to. Once they have completed the test or the time has elapsed, a progress report on how they did is sent to the recruiter

Hvad er testens varighed?

DevSkiller’s iOS developer interview questions are flexible when it comes to duration. This can be set depending on your preferences. Our task wizard comes with predefined tests that have default settings including duration. However, you have the option to set your own test duration if you would prefer. It is even possible to set time limits for individual questions within a test.
