About the Test

This Hibernate test is designed mainly to assess the candidates in Association Relationship 1-m,1-1, Embeddable Primary key, Embeddable ID, EntityManager API, Java, and JPA Annotation skills.

Hibernate is an open-source object-relational mapping( ORM) tool that provides a framework to collude object-acquainted sphere models to relational databases for web operations. Object-relational mapping is grounded on containerizing objects and the abstraction that provides that capacity. Abstraction makes it possible to address, access, and manipulate objects without considering how they’re related to their data sources.

Hibernate charts Java classes to database tables and from Java data types to SQL data types and relieves the inventor from utmost common data continuity-related programming tasks.
Hibernate reduces lines of law by maintaining object-table mapping and returns results to operation in Java objects. It relieves programmers from the homemade running of patient data, reducing development time and conservation costs.

Customer Satisfaction

Testlify helps you identify the best talent from anywhere in the world, with a seamless experience that candidates and hiring teams love every step of the way.

1

Java

Java is a programming language that is commonly used in conjunction with the Hibernate framework. Hibernate is an open-source, Java-based object-relational mapping (ORM) framework that provides a framework for mapping object-oriented domain models to relational databases. In order to use Hibernate, a developer must be familiar with Java and have a working knowledge of its syntax and concepts.

2

Association, Relationship 1-m,1-1

In Hibernate, association, relationship, and mapping refer to the way in which objects in a Java application are related to data stored in a database. These relationships can be one-to-one (1-1), one-to-many (1-m), or many-to-many (m-m).1-1 relationships occur when a single object in the Java application is related to a single record in the database. 1-m relationships occur when a single object in the Java application is related to multiple records in the database.

3

Entity manager API

In Hibernate, the EntityManager API is a interface that provides a set of methods for managing the persistence of objects. The EntityManager API provides various methods for managing the persistence of objects, including methods for creating, updating, deleting, and querying objects. It also provides methods for managing transactions, which are used to group multiple database operations into a single unit of work.

4

JPA Annotations

In Hibernate, JPA annotations are used to specify mapping metadata for objects and their properties. These annotations are part of the Java Persistence API (JPA), which is a Java specification for accessing, persisting, and managing data between Java objects/classes and a relational database.

The test is created by a subject-matter expert

Testlify’s skill tests are designed by experienced SMEs (subject matter experts). We evaluate these experts based on specific metrics such as expertise, capability, and their market reputation. Prior to being published, each skill test is peer-reviewed by other experts and then calibrated based on insights derived from a significant number of test-takers who are well-versed in that skill area. Our inherent feedback systems and built-in algorithms enable our SMEs to refine our tests continually.

Top five hard skills interview questions for Hibernate

1. Can you walk us through the architecture and components of Hibernate?
Why this Matters?

Understanding the architecture and components of Hibernate is crucial for effectively utilizing the framework. The answer to this question will give insight into the candidate’s technical knowledge and ability to work with Hibernate effectively.

What to listen for?

The candidate should be able to discuss the various components of Hibernate, including the SessionFactory, Session, and Transaction objects, as well as the configuration process. They should also demonstrate an understanding of the role each component plays in the overall framework.

2. Can you discuss your experience with mapping Java objects to database tables in Hibernate?
Why this Matters?

Mapping Java objects to database tables is a core function of Hibernate, and it requires a strong understanding of object-relational mapping (ORM) concepts and the ability to implement these mappings effectively. The answer to this question will give insight into the candidate’s knowledge of ORM and their ability to work with Hibernate.

What to listen for?

The candidate should be able to discuss their experience with mapping Java objects to database tables, including the use of annotations and XML configuration. They should also demonstrate an understanding of how these mappings are used in Hibernate to persist data to the database.

3. Can you walk us through your experience with Hibernate query language (HQL)?
Why this Matters?

HQL is a key aspect of Hibernate, and it requires a strong understanding of the syntax and the ability to write effective queries. The answer to this question will give insight into the candidate’s knowledge of HQL and their ability to work with Hibernate.
