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.

Test candidates on core Java, Spring & Hibernate Hiring Test topics

Java syntax and basics: Java syntax and basics refers to the fundamental concepts and rules of the Java programming language. It covers topics such as variables, data types, operators, control structures, and basic input/output. This skill should be measured in the test to assess the candidate's understanding of the core syntax and foundational concepts of Java programming.

Java OOPs: Java OOPs stands for Object-Oriented Programming in Java. It involves the use of classes, objects, inheritance, polymorphism, and encapsulation to organize and structure code. This skill should be measured in the test to evaluate the candidate's ability to design and implement object-oriented solutions using Java.

Working with Databases in Java: Working with Databases in Java involves connecting to a database, executing SQL queries, and retrieving and manipulating data. Candidates should possess knowledge of JDBC (Java Database Connectivity) and understand database concepts such as tables, columns, and primary keys. This skill should be measured in the test to gauge the candidate's proficiency in integrating Java with databases.

Java data structures: Java data structures are used to store and organize data efficiently. Common data structures in Java include arrays, linked lists, stacks, queues, and trees. Candidates should be familiar with the characteristics and appropriate usage of different data structures. This skill should be measured in the test to assess the candidate's understanding of data organization and manipulation in Java.

Basics of Spring framework: The Spring framework is a popular Java framework that provides a comprehensive infrastructure for developing Java applications. It offers features such as dependency injection, aspect-oriented programming, and MVC (Model-View-Controller) architecture. This skill should be measured in the test to evaluate the candidate's knowledge of the core concepts and functionalit

Spring bean lifecycle: The Spring bean lifecycle refers to the sequence of events that occur during the creation, initialization, and destruction of a Spring bean. It includes phases such as instantiation, property injection, and initialization callbacks. Candidates should understand the different stages and methods involved in the Spring bean lifecycle. This skill should be measured in the test to assess the candidate's understanding of how Spring manages the lifecycle of beans.

Securing web applications with Spring Security: Spring Security is a powerful framework for implementing security measures in Java web applications. It provides features such as authentication, authorization, and access control. Candidates should be familiar with concepts like user authentication, password encryption, and role-based access control. This skill should be measured in the test to evaluate the candidate's ability to implement secure web applications using Spring Security.

Hibernate ORM (Object Relational Mapping): Hibernate ORM is a Java framework that simplifies the process of mapping Java objects to relational database tables. It allows developers to interact with databases using object-oriented approaches, rather than writing SQL queries. Candidates should understand concepts like object-relational mapping, entities, relationships, and transactions. This skill should be measured in the test to assess the candidate's proficiency in using Hibernate for database access and manipulation.

Stored Procedure Queries: Stored Procedure Queries involve the creation and execution of database queries that are stored and reused on the database server. Candidates should be familiar with the syntax and usage of stored procedures in the target database system, as well as how to call them from Java code. This skill should be measured in the test to evaluate the candidate's ability to work with stored procedures in a Java application.

Hibernate Sessions: Hibernate Sessions involve managing the interaction between Java objects and the database. Sessions provide methods for querying, saving, updating, and deleting data. Candidates should know how to open, close, and utilize Hibernate Sessions effectively. This skill should be measured in the test to assess the candidate's understanding of Hibernate's session management and data persistence capabilities.

Java Programming: Java Programming refers to the overall ability to write clean, efficient, and readable code in the Java programming language. It encompasses all the aforementioned skills and extends to problem solving, algorithm design, and code optimization. This skill should be measured in the test to evaluate the candidate's overall proficiency and competence in Java development.

What roles can I use the Java, Spring & Hibernate Test for?

Here are few roles for which we recommend this test:

  • Java Developer
  • Full Stack Java Developer
  • Backend Developer
  • Java Programmer
  • Enterprise Java Developer
Can I combine the Java, Spring & Hibernate Test with SQL questions?

Yes, you can request a custom test that includes SQL questions. Check out our Java, Spring & SQL Test for an example of how we assess SQL skills along with Java and Spring.

How to use the Java, Spring & Hibernate Test in my hiring process?

Use this test as a pre-screening tool at the beginning of your recruitment process. Add a link to the assessment in your job post or invite candidates by email. Adaface helps you find the most skilled candidates quickly.

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.

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.

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.

What is the cost of using this test?

You can check out our pricing plans.
