Solution Overview

Problem

The recruitment process for job positions is time-consuming and resource-intensive, especially with the challenges of remote work and the difficulty of organizing face-to-face interviews, which can be costly and impractical during pandemics.

Innovation Solution

An automated interview apparatus and method using telecommunication networks to select candidates, monitor communication sessions, convert audio streams to text data, assess language quality, and determine matching values for job positions, while detecting fraud and synchronizing virtual avatars with questions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If face-to-face interviews are organized, then recruitment accuracy can be improved through direct interaction, but travel costs and time consumption increase significantly

Engineering Contradiction:
Improverecruitment accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical face-to-face interview system with an automated telecommunication-based interview system. The automated apparatus conducts interviews remotely via audio communication, eliminating the need for physical travel while maintaining interview functionality. This substitution resolves the contradiction by preserving recruitment assessment capabilities without the time and cost overhead of in-person meetings.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an automated interviewing apparatus as an intermediary between recruiters and candidates. This intermediary conducts interviews through telecommunication networks, enabling remote assessment without requiring direct physical interaction. The intermediary resolves the contradiction by facilitating accurate candidate evaluation while eliminating travel requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If more candidates are considered, then the probability of finding a perfect match increases, but the time and cost of the recruitment process increase

Engineering Contradiction:
Improveprobability of finding perfect matchVSAvoidrecruitment process efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The automated interviewing apparatus enables candidates to conduct preliminary self-assessments and allows the system to automatically evaluate candidates against job criteria. This self-service capability allows recruiters to efficiently screen large numbers of candidates without proportionally increasing time investment, resolving the contradiction between considering more candidates and maintaining process efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the evaluation parameters from time-intensive human assessment to automated analysis of audio streams and text data. By transforming candidate evaluation into measurable parameters like language quality, understandability, and information quality, the system can process multiple candidates simultaneously without linearly increasing time costs, thus resolving the efficiency contradiction.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automated interview systems are implemented, then time consumption is reduced, but the ability to assess nuanced candidate qualities may deteriorate

Engineering Contradiction:
Improverecruitment efficiencyVSAvoidcandidate assessment accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The automated apparatus incorporates feedback mechanisms that analyze audio streams to determine language quality, understandability, and information quality features. The system provides continuous feedback on candidate responses against expected content, enabling nuanced assessment of candidate qualities while maintaining automated efficiency. This feedback loop resolves the contradiction by preserving assessment depth without sacrificing processing speed.

Inventive Principle:
Principle #23Feedback

AI summary

Apparatus (1) for automatically conducting an interview over a telecommunication network (4), with at least one candidate party (2a, 2b, ... 2N) to an open job position; comprising means for: - selecting (S0) a candidate party; - initiating (S1) a communication session between the candidate party and an automated interviewing party; - monitoring (S2) the communication session by receiving an audio stream; - converting (S3) language of said audio stream into text data - determining (S4), from said text data, at least first understandability quality features (UQFA, UQFG) and an information quality feature (IQF), said first understandability quality feature being representative of at least word articulation and grammar correctness within said language, and said information quality feature being representative of a comparison of the semantic content of the audio stream with an expected content; assessing (S5) a matching value of the candidate party.
