Medium Rewards Activities Order Database Connection	Solve
A new popular app tracks the activities performed by its users and grants them rewards based on each individual's total activities performed in a year. This data is maintained in a database table (activitesinfo), with the following columns: userid, totalactivities, reward. This year, due to fundraising activity, the company has decided to further reward its users by enhancing the reward as per the following formula: If reward < = 4000, increase it by 2%, If 4000 < reward <= 8000, increase it by 4%, If reward > 8000, increase it by 6%. The tech team has written three different scripts to calculate increment for each slab, each script is to run as a separate transaction. Here are the three scripts: Script 1: For users with reward <= 4000, set reward = reward * 1.02 Script 2: For users with reward > 4000 and reward <= 8000, set reward = reward * 1.04 Script 3: For users with reward > 8000, set reward = reward * 1.06 Each script is to be executed separately. Which of the following options will update the rewards as expected: A: Execute Script 1 followed by Script 2 followed by Script 3 B: Execute Script 2 followed by Script 3; Script 1 running concurrently throughout C: Execute Script 3 followed by Script 2; Script 1 running concurrently throughout D: Execute Script 3 followed by Script 2 followed by Script 1 E: Execute Script 2 followed by Script 3 followed by Script 1

Test candidates on core SOLID, Technical Aptitude & Coding Hiring Test topics

SOLID Principles: The SOLID principles are a set of five design principles in object-oriented programming that aim to make software systems more maintainable and extensible. They include the Single Responsibility Principle (SRP), Open/Closed Principle (OCP), Liskov Substitution Principle (LSP), Interface Segregation Principle (ISP), and Dependency Inversion Principle (DIP). By measuring this skill, recruiters can assess a candidate's understanding of these principles and their ability to apply them in software design.

Object Oriented Design: Object-oriented design is a programming paradigm that organizes software applications into modular components called objects, which have state, behavior, and identity. It promotes code reusability, maintainability, and scalability. Measuring this skill helps recruiters evaluate a candidate's proficiency in designing software systems using the principles of object-oriented programming.

Technical Aptitude: Technical aptitude refers to a candidate's ability to understand and apply technical concepts and principles in problem-solving and decision-making scenarios. It involves skills such as logical reasoning, analytical thinking, attention to detail, and problem-solving ability. Assessing technical aptitude in this test allows recruiters to gauge a candidate's overall technical competency and their potential to excel in a technical role.

Data Structures: Data structures are the fundamental building blocks of organizing and storing data in computer memory. They provide efficient ways to perform operations like searching, sorting, and manipulating data. Measuring this skill enables recruiters to assess a candidate's knowledge and ability to choose appropriate data structures for efficient algorithmic problem-solving and software development.

We were able to close 106 positions in a record time of 45 days! Adaface enables us to conduct aptitude and psychometric assessments seamlessly. My hiring managers have never been happier with the quality of candidates shortlisted.

Amit Kataria, CHRO, Hanu

We evaluated several of their competitors and found Adaface to be the most compelling. Great library of questions that are designed to test for fit rather than memorization of algorithms.
