How to hire core data developers? Skills to look for, interview questions, and more

A core data developer performs the critical responsibility of structuring and managing data in an application. They design data models, build databases, and optimize data retrieval for peak performance. Core data developers play a critical role in building efficient data-intensive applications, making them sought-after professionals. However, onboarding a talented core data developer is a challenging task due to high competition. To make your task easier, we have created a comprehensive guide on how to hire core data developers. Let's get started.

Skills to look for in a core data developer?

At a high level, hire core data developers who have the following skills in their arsenal:

1. High-level proficiency in core data framework

Core data frameworks enable developers to design optimized data models and structures, ensuring efficient storage and data within the application's database. Proficiency in core data framework helps developers create complex queries and retrieve data effortlessly, ensuring quick and accurate access to the required information thus improving user experience.

Additionally, expertise in core data frameworks allows developers to transform data into different formats and structures to meet the application's needs. Therefore, when you hire core data developers, evaluate their proficiency in the core data framework.

2. Proficiency in Swift

When working with iOS development, it is of utmost importance to understand the ins and outs of Swift language. Apple uses this language to develop iOS mobile applications and an experienced developer must have a fair understanding of both the programming languages Swift. That's why you should hire core data developers who have a clear and complete understanding of Swift.

3. Understanding of code versioning tools

Code versioning tools are crucial for Software development. Popular tools such as Git, SVN, Mercurial, etc., help developers control each step in the application development process and enable them to track even the minute changes with full traceability. Companies that hire core data developers with adequate knowledge of working with such platforms can efficiently scale their projects.

4. In-depth knowledge of databases

Knowledge of databases is necessary for successful software development. The database is where all the data is stored, and you should not hire core data developers who have very little knowledge of database storage and management. Instead, you should recruit a candidate who has extensive knowledge of various DBMS technologies such as MongoDB, Oracle, MySQL, SQLServer, etc.

5. Experience with the latest iOS frameworks

Frameworks are designed to help in building efficient iOS applications and along with the core data framework, a skilled developer should have the knowledge of libraries, such as SwiftUI, Quartz Core, realm, RxSwift, and others. Using them helps in improving the performance of applications. Besides these frameworks, when you hire a core data developer, you must also examine the candidate for sufficient knowledge in Xcode, the most widely used integrated development environment (IDE) that helps develop iOS applications.

6. Familiarity with UI and UX

UI/UX helps in improving the overall looks of the applications and its knowledge helps developers to understand the structure and visually analyze the application. When you hire core data developers, they must have familiarity with the design concepts and adequate experience to create exciting UI/UX design for applications.

Create a hiring funnel

Creating a hiring funnel will provide you with numerous benefits, like assisting you in identifying the top skills to hire core data developers who will fit into your company's culture.

Top interview questions to hire core data developers

Hiring for a new skill is always challenging, even if you’ve been a part of recruitment processes for quite some time. But it is also critical to the success of your project that you hire remote core data engineers who are the right fit for your team. Here is a list of possible questions that you can use to test the candidates.

The object graph is a collection of objects that are connected with one another and Core Data manages these objects efficiently.

Core Data manages your application’s model layer by providing a set of classes that support the layer, for example, NSPersistentContainer to set up the model, context, and store coordinator simultaneously, NSManagedObjectModel for app’s types, including their properties and relationships, NSManagedObjectContext to tracks changes to instances of your app’s types, and NSPersistentStoreCoordinator to save and fetch instances of your app’s types from stores.

Core Data supports four store types - SQLite, Binary, XML, and In-Memory, where XML store is not available on iOS.

It is a repository where managed objects are stored and is used to save and present any type of records that hold the last-saved values of the managed object.

Two concurrency types are NSMainQueueConcurrencyType and NSPrivateQueueConcurrencyType.
