What interview techniques should you use to hire the best Objective-C developers?
Before hiring the best Objective-C developers, it’s important to note that the goal of the interview is to gauge the possible candidate’s ability and understanding within a limited time.
Here are some suggested interview questions and techniques that you can ask or apply to determine the best Objective-C candidate for you and your project.
Ask them to describe the structure of their recent project
It’s important to ask the candidates to describe their recent project in detail. With this method, you can ascertain two things.
First, you can confirm the candidates’ level of expertise in the development process and their mastery of the programming language. This shows other skills that the candidates offer aside from what is listed or mentioned in their resume. One thing to pay attention to is how much the candidates’ are able to discuss their project in detail as this can indicate the level of their involvement and commitment to the project.
Second, this shows you how well the candidate can present and explain a technical concept. Gauge the demonstration of the candidate based on how understandable it is from a layman’s point of view. Also, note it is also important to pay attention to their non-verbal cues throughout their demonstration. Evaluate the candidate’s soft skills such as eye contact, body language, posture, and hand gestures to determine the level of confidence and how comfortable are they to public speaking. This is essential if you are specifically looking for a lead Objective-C developer; the ability to be an effective communicator and explain concepts to a non-technical audience is a very important skill.
Conduct Technical Tests
Technical tests are highly suggested as it helps to fully determine what the Objective-C developer can do. Let them take online programming tests as these technical assessments give an idea of the candidate’s critical thinking and problem-solving skills. It’s important to be thorough with your interviews; don’t just hire a candidate that only knows the know-how at face value. Instead, hire someone who knows how to assess, think, and solve.
Here are some sample questions and challenges that you can ask your candidate.
Q: Name four important data types found in Objective-C.
A:
NSString: Represents a string.
CG float: Represents a floating point value.
NSInteger: Represents an integer.
BOOL: Represents a boolean.
Q: What is the purpose of managed object context (NSManagedObjectContext) in Objective-C and how does it work?
A: Managed object context exists for three reasons: life-cycle management, notifications, and concurrency. It allows the developer to fetch an object from a persistent store and make the necessary modifications before deciding whether to discard or commit the changes back to the persistent store. The managed object context tracks these changes and allows the developer to undo and redo changes.
Q: Find the bug in the Objective-C code below. Explain your answer.
@interface HelloWorldController : UIViewController
@property (strong, nonatomic) UILabel *alert;
@end
@implementation HelloWorldController
- (void)viewDidLoad {
CGRect frame = CGRectMake(150, 150, 150, 50);
self.alert = [[UILabel alloc] initWithFrame:frame];
self.alert.text = @"Hello...";
[self.view addSubview:self.alert];
dispatch_async(
dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0),
^{
sleep(10);
self.alert.text = @"World";
}
);
}
@end
A: All UI updates must be performed in the main thread. The global dispatch queue does not guarantee that the alert text will be displayed on the UI. As a best practice, it is necessary to specify any updates to the UI occur on the main thread, as in the fixed code below:
dispatch_async(
dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0),
^{
sleep(10);
dispatch_async(dispatch_get_main_queue(), ^{
self.alert.text = @"World";
});
});
Q: You’ve just been alerted that your new app is prone to crashing. What do you do?
A: This classic interview question is designed to see how well your prospective Objective-C developer can solve problems. What you’re looking for is a general methodology for isolating a bug and their ability to troubleshoot issues like sudden crashes or freezing. In general, when something goes wrong within an app, a standard approach might look something similar to this:
- Determine the iOS version and the model of the device.
- Gather enough information to reproduce the issue.
- If possible, acquire the device logs.
- Once you have an idea as to the nature of the issue, acquire tooling or create a unit test and begin debugging.
A great answer would include all of the above, with specific examples of debugging tools, and a firm grasp of software debugging theory—knowledge on what to do with compile-time errors, run-time errors, and logical errors. The one answer you don’t want to hear is the haphazard approach—visually scanning through hundreds of lines of code until the error is found. When it comes to debugging software, a methodical approach is a must.
Q: What needs to be modified in order to correctly manage memory when compiled with ARC (Automatic Reference Counting)?
- (void)printFontCopyright {
CTFontRef font = CTFontCreateWithName(CFSTR(“Helvetica”), 12, NULL);
NSStrong *fontName = CTFontCopyName(font, kCTFontCopyrightNameKey);
NSLog (@”%@”, fontName);
CFRelease(font);
}
A: Line 2 should be replaced with:
NSString *fontName
= CFBridgingRelease (CTFontCopyName(font, kCTFontCopyrightNameKey));

What is the dedicated hiring model?
The Dedicated Hiring Model allows clients to have close control over the hiring process. It assimilates the dedicated offshore team you selected with your existing in-house developers, essentially reducing the likelihood of any miscommunication and allowing the offshore Objective-C development team to become a part of the project’s infrastructure and design.
Because of its flexible nature, it’s considered as one of the best engagement models. With this model, you and your team can request for tech talents, resources and types of equipment at any given time corresponding to the current requirements of the project. The Dedicated Hiring Model allows the in-house team to scale up or down with relative ease.
Another important thing to note is that the payment method is made simpler and easier for you; you would only have to pay once and this fee already includes the offshore team member’s monthly salary and the outsourcing provider’s service fee.
