Assessment Rubric Overview: "Sum Largest Smallest" Problem

This assessment evaluates a candidate's proficiency in parsing structured data, implementing fundamental algorithms, and demonstrating a clear understanding of time complexity and edge case handling. The problem requires parsing a string of integers organized into rows, identifying the largest and smallest numbers in each row, computing their sum, and returning the cumulative sum of these values.

Core Competencies and Skills Evaluated:

• String Parsing and Data Extraction: Ability to effectively parse a structured string input, separating rows and individual integers.

• Algorithmic Problem Solving: Proficiency in identifying the largest and smallest numbers within each row and computing their sum.

• Time Complexity Analysis: Understanding and articulating the time complexity of the solution, including considerations for edge cases such as empty rows or single-element rows.

• Edge Case Handling: Demonstrating the ability to anticipate and handle various edge cases, ensuring the solution is robust and reliable.

Behavioral Traits and Problem-Solving Approaches Assessed:

• Analytical Thinking: Approach to breaking down the problem into manageable components and developing a systematic solution.

• Attention to Detail: Carefulness in parsing input data and accurately implementing logic to handle all specified requirements.

• Communication Skills: Clarity in articulating the thought process, solution approach, and understanding of time complexity and edge cases.

Assessment Process Expectations:

Candidates can expect a structured interview process that includes:

• Technical Screening: Initial assessment of problem-solving skills through coding exercises or algorithmic questions.

• Case Study Presentation: Presentation of a case study or problem-solving scenario, followed by a discussion to evaluate depth of understanding and approach.

• Behavioral Interview: Evaluation of interpersonal skills, cultural fit, and alignment with company values.

Preparation Recommendations:

• String Manipulation: Practice parsing and processing strings, focusing on extracting and manipulating data efficiently.

• Algorithm Design: Strengthen skills in designing algorithms to identify extremal values within datasets and compute aggregate metrics.

• Complexity Analysis: Review concepts related to time and space complexity, and practice analyzing the efficiency of algorithms.

• Edge Case Identification: Develop strategies for identifying and handling edge cases to ensure robust solutions.

Evaluation Criteria and Technical Concepts:

• Correctness: Accuracy in implementing the solution to meet all specified requirements.

• Efficiency: Optimal use of resources, with attention to time and space complexity.

• Clarity: Readable and maintainable code with appropriate documentation.

• Problem-Solving Approach: Logical and systematic approach to solving the problem, including handling of edge cases.
