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.
Key features
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.
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.
If you think DevSkiller iOS tests are what your business needs, but are still unsure, check out the following case study:
Plutora is a market leader in value stream management, with release, test environment, and analytics solutions for enterprise IT.
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.
“Thanks to automating the screening stage, we were able to reduce the interview rate by 50%. At the same time, the quality of candidates who make it to the interview stage is now much greater. DevSkiller adds an extra layer of quality to our technical hiring process”
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.
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.
