iOS Developer Test

An iOS developer test can be used by hiring teams to assess candidates on the necessary skills and expertise for an iOS developer.

  • What is an iOS developer test?

    The iOS developer test is designed to help recruiters ensure that they make the best hiring decisions, based on test results that demonstrate the relevant skills and abilities of the candidates.

    iOS developers need to be able to use the Apple-specific technologies for creating, coding and producing workable apps that meet the requirements for devices that run on iOS.

    Hiring for an iOS developer can be difficult, as a resume alone may not evidence the aptitudes and skills sought. That is where an iOS developer test can help.

About the iOS Developer Test

The iOS developer test challenges applicants to prove that they have the skills and knowledge needed to be a successful iOS developer.

The test requires problems to be solved using iOS-specific programming languages, structures and environments, and gives unbiased results that can be used as part of the recruitment process to help screen candidates.

Simple to administer to applicants, and easy to scale when necessary for large candidate pools, the test can reduce the cost-per-hire and help your business make the best recruitment decisions.

  • Why should you use an iOS developer test for recruiting?

    iOS developers need special skills and knowledge to work effectively in the Apple ecosystem, such as Swift, Xcode IDE, and JSON, as well as understanding of debugging, databases, coding, and UX design.

    Looking for a competent, professional iOS developer starts with the right job description. But when potentially hundreds of applicants respond with similar qualifications and experiences listed on their resume, deciding which candidates to take forward can be difficult.

    Applying the iOS developer test to a number of candidates allows the recruitment team to make decisions based on proven skills and competencies.

Results for the iOS Developer Test along with other assessments the candidate takes will be compiled to produce a candidate report. The report is automatically generated and available both online and as a downloadable pdf so they can be shared with other team members and employees alike.

How our test assesses iOS developer skills

Candidates will need to answer a range of questions that measure industry-specific technical skills where applicable, soft skills (e.g. teamwork), aptitude (e.g. error checking) and relevant personality dimensions (e.g. detail orientation). The results present a holistic view of how well suited each candidate is for the job at hand, using a data-driven approach.

The format varies by type of question, including multiple-choice for aptitude and technical skills, situational judgement for soft skills and agreement on a Likert scale for the personality dimensions. This approach ensures candidates are being assessed in an accurate and fair manner, and that results reflect the true underlying qualities of each candidate.

The characteristics, abilities and knowledge necessary to be an iOS developer were identified using the US Department of Labor's comprehensive O*NET database. O*NET is the leading source of occupational information that is constantly updated by collecting data from employees in specific job roles.

During the development process, test questions were rigorously analysed to maximise reliability and validity in line with industry best practices. They were created by our team of I/O psychologists and psychometricians – who collaborated with subject-matter-experts – and field-tested with a representative sample of job applicants who have varying experience, just like you might find in a talent pool.

Each test is reviewed by a panel of individuals representing diverse backgrounds to check for any sensitivity, fairness, face validity and accessibility issues. This ensures each candidate has a fair chance of demonstrating their true level of expertise.

Our iOS developer test is monitored to ensure it is up-to-date and optimised for performance.
