Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a human interviewer orally asks technical questions to assess candidate skills, then the evaluation can be comprehensive and nuanced, but the process becomes time-consuming and subjective
Solution Approach 1:
The patent introduces an automatic evaluation system as an intermediary between the interviewer and candidate. This system includes a question management module that selects and presents questions, a response analysis module that evaluates answers using natural language processing, and an automatic scoring mechanism. The intermediary automates the time-consuming tasks of question delivery and answer evaluation while maintaining comprehensive assessment capabilities through AI-powered analysis of technical responses.
Solution Approach 2:
The patent replaces the mechanical human interview process with an automated electronic system. Instead of a human interviewer orally asking questions and manually evaluating answers, the system uses computer-based question delivery, automated response capture, and AI-driven analysis. The mechanical substitution eliminates interviewer subjectivity and time constraints while preserving the ability to conduct comprehensive technical assessments through structured questionnaires and automated scoring algorithms.
2Productivity
If evaluation software is used to automate question delivery and answer collection, then interviewer time is saved, but the software cannot independently assess the validity of technical answers
Solution Approach 1:
The patent transforms the evaluation process by changing the parameters of answer analysis. Instead of simple keyword matching or multiple-choice scoring, the system employs natural language processing to analyze the semantic content, technical accuracy, and completeness of candidate responses. The response analysis module evaluates parameters such as technical depth, relevance to the position, and correctness of concepts, enabling automated assessment of open-ended technical answers with high precision.
Solution Approach 2:
The patent implements a feedback mechanism where the automatic evaluation system provides detailed analysis of candidate responses. The response analysis module generates feedback on technical accuracy, identifies gaps in knowledge, and compares answers against ideal responses in the database. This feedback loop enables the system to independently validate technical answers while maintaining high measurement precision, as the AI continuously learns from and refines its evaluation criteria based on established technical standards.
3Ease of operation
If multiple-choice questions are used to simplify the evaluation process, then automation becomes easier, but the questions cannot be complex enough for technical positions requiring specific thorough skills
Solution Approach 1:
The patent segments the evaluation process into distinct phases: question selection from a structured database, candidate response capture, automated analysis of technical content, and scoring based on multiple criteria. This segmentation allows the system to handle complex open-ended technical questions while maintaining ease of automation. Each segment is processed independently by specialized modules, enabling the system to manage complexity without sacrificing operational simplicity or assessment accuracy.

AI summary
The invention relates to a method for automatically evaluating a candidate using a set of questions implemented by an automatic evaluation system, including a control module, a database, a user interface and a language model module. The method includes a first phase being iterative and includes, at each iteration, selecting a question, sending the selected question to the user interface, receiving a candidate's answer, requesting the language model module for an accuracy score reflecting the accuracy of the candidate's answer relatively to a model answer, and receiving the requested accuracy score. The iterative first phase is carried out until an accuracy score has been received. The method also includes a second phase that includes computing an evaluation score of the candidate using the received accuracy scores.
