**Logical Reasoning**: Logical reasoning assesses the ability to analyze and evaluate arguments based on logic and evidence. It involves identifying the underlying assumptions, deductions, and conclusions in a given statement or set of statements. This skill is essential to measure in the test to gauge a candidate's ability to think critically, solve complex problems, and make rational decisions.

**Data Visualization**: Data visualization evaluates an individual's capability to represent and communicate data visually through charts, graphs, and diagrams. It encompasses organizing and presenting information in a visually appealing and easily understandable format. This skill is important to measure as it indicates an individual's proficiency in interpreting data, identifying patterns, and drawing meaningful insights.

**Data Sufficiency**: Data sufficiency measures the ability to determine if the available information is adequate to solve a problem or answer a question. It involves analyzing the given data, identifying what additional information is required, and evaluating if the provided data is sufficient to reach a valid conclusion. Assessing this skill helps in understanding a candidate's analytical thinking, resourcefulness, and sound decision-making abilities.

**Verbal Reasoning**: Verbal reasoning assesses the ability to understand, interpret, and analyze written information. It includes evaluating the logical consistency and coherence of statements, drawing inferences, and deducing conclusions from textual content. Measuring this skill is crucial to evaluate a candidate's reading comprehension, critical thinking, and communication skills.

**Numerical Reasoning**: Numerical reasoning evaluates a candidate's aptitude to work with numbers, understand and interpret numerical data, and solve mathematical problems. It involves analyzing numerical patterns, performing calculations, and demonstrating numerical problem-solving abilities. Assessing this skill helps in determining a candidate's quantitative abilities, logical thinking, and attention to detail.

**Critical Thinking**: Critical thinking refers to the ability to objectively analyze and evaluate information, arguments, and situations. It involves logical reasoning, sound judgment, and maintaining an unbiased perspective while making decisions or solving problems. Measuring this skill is essential to assess an individual's ability to think independently, evaluate different perspectives, and arrive at well-informed, logical conclusions.

**Problem Solving**: Problem-solving skill examines an individual's capacity to identify, analyze, and resolve complex problems efficiently and effectively. It requires logical thinking, creativity, and systematic approach for finding solutions. Measuring this skill is crucial to evaluate a candidate's ability to handle challenges, adapt to changing situations, and make informed decisions in a professional environment.
