Online Objective-C Test

Objective-C is the primary programming language you use when writing software for OS X and iOS. It’s a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods.

The Objective-C test enables employers and recruiters to identify potential prospects by evaluating their working skills and job readiness. For this reason, the emphasis is laid upon evaluating the knowledge of applied skills gained through real work experience, rather than theoretical knowledge. Objective-C test enables recruiters and hiring managers to evaluate the Objective-C programming skills of the applicant at an initial stage of hiring.

Our Objective-C online test is designed by subject matter experts to analyze the job skills of applicants to assess and hire Objective-C programmer.
