Here's a way to insert 100,000 entries into Hibernate: Which of the following statements are true about this implementation? A: The code might fail with OutOfMemoryException B: Long running transactions can deplete connection pool C: Every insert statement requires a database roundtrip
Easy Registration Queue Logic Queues	Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10
Medium Visitors Count Strings Logic	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Hibernate Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the Hibernate Online Test?

Hibernate Basics
Hibernate Basics covers the core principles, concepts, and features of Hibernate framework. It includes understanding Hibernate architecture, session management, session factory, persistence classes, and object-relational mapping.
Hibernate Configuration
Hibernate Configuration focuses on setting up the necessary configurations for Hibernate to work efficiently. This skill involves configuring database connections, mapping files, Hibernate properties, and various settings related to caching and transactions.
Mapping Entities
Mapping Entities is the skill of defining the relationship between Java objects and database tables. It covers the use of annotations or XML mappings to map classes, attributes, and associations to corresponding database entities.
Hibernate Query Language (HQL)
Hibernate Query Language (HQL) enables developers to write queries using object-oriented concepts instead of dealing with SQL directly. It allows complex querying and manipulation of data using a familiar syntax similar to SQL.
Criteria API
The Criteria API provides a more programmatic way to define queries in Hibernate. This skill involves creating and executing criteria queries using a fluent API, allowing dynamic query building and flexible filtering options.
Caching
Caching is an important aspect of Hibernate to improve performance. This skill covers different levels of caching, such as first-level cache, second-level cache, query caching, and cache configurations to optimize data access and reduce database hits.
Transactions
Transactions ensure data integrity and consistency in a database. This skill involves understanding the concept of ACID properties (Atomicity, Consistency, Isolation, Durability) and implementing transaction management using Hibernate to handle data modifications and ensure data integrity.
Annotations
Annotations in Hibernate provide a way to define mappings and configurations directly through Java code, reducing the need for XML mapping files. This skill covers the use of various annotations like @Entity, @Table, @Column, @Id, and other lifecycle annotations to define mappings and access database entities.
Inheritance
Inheritance is a powerful feature in Hibernate that allows mapping object hierarchies to database tables. This skill includes understanding different inheritance strategies, such as table per class hierarchy, table per subclass, and table per concrete entity, and their implications on query efficiency and database schema design.
Integration
Integration involves integrating Hibernate with other technologies and frameworks. This skill covers integrating Hibernate with Spring, JPA (Java Persistence API), and other ORM frameworks to leverage their capabilities and enhance application development and maintainability.
Performance Optimization
Performance Optimization in Hibernate includes techniques and practices to improve the performance of database operations. This skill covers optimizing queries, managing session and transaction boundaries, tuning caching options, and utilizing batch processing and lazy loading to minimize database roundtrips and enhance application responsiveness.
Best Practices
Best Practices in Hibernate include following industry-standard coding conventions, design patterns, and techniques to ensure efficient, maintainable, and scalable Hibernate applications. This skill covers topics like session management, exception handling, error logging, database schema design, and performance tuning to produce high-quality and reliable Hibernate applications.

Hibernate Hiring Test FAQs

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

Non-googleable questions
IP proctoring
Screen proctoring
Web proctoring
Webcam proctoring
Plagiarism detection
Secure browser
Copy paste protection

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.
