About our client
A major US-based technology consulting firm that develops AI-powered recruitment platforms for enterprise clients. Their systems screen millions of job applications annually for Fortune 500 companies across industries, making critical first-pass decisions about candidate advancement.
Industry
Objective
The firm needed to rigorously test their recruitment AI for hidden biases and potential discrimination patterns before deployment at scale. They required experts to identify subtle risks that could disadvantage certain groups, even when prohibited characteristics were removed from training data.
- Detect proxy variables encoding protected characteristics
- Evaluate patterns perpetuating historical hiring biases
- Test for language-based discrimination against non-native speakers
- Assess socioeconomic barriers from education preferences
- Identify regional biases in training datasets
The challenge
Recruitment algorithms often appear neutral but can reinforce systemic bias through indirect factors. While earlier audits checked for obvious markers, subtle discrimination risks remained hidden.
- Proxy variables inadvertently encoding protected traits
- Resume screening reinforcing historical hiring biases
- Language analysis disadvantaging non-native speakers
- Education filters creating socioeconomic exclusion
- Regional training data introducing geographic bias
- Previous audits limited to surface-level markers
CleverX solution
CleverX assembled a panel of legal, HR, and data experts to design a bias testing program that combined legal review, psychological expertise, and fairness analytics.
Expert recruitment:
- Employment law attorneys specializing in discrimination cases
- Industrial-organizational psychologists understanding hiring bias
- Diversity and inclusion consultants with corporate experience
- Data scientists experienced in algorithmic fairness testing
Bias testing framework:
- Creation of synthetic candidate profiles testing various bias vectors
- Analysis of decision patterns across demographic groups
- Identification of proxy variables correlating with protected classes
- Testing of intersectional bias affecting multiple characteristics
Validation approach:
- Statistical analysis of outcomes across candidate groups
- Documentation of potential discrimination patterns
- Legal review of identified issues for compliance risks
- Development of bias mitigation strategies
Impact
The evaluation was phased to ensure systematic identification and mitigation of bias.
Week 1-2: Expert team analyzed the recruitment AI's decision-making process
Weeks 3-4: Development of comprehensive test scenarios covering various bias types
Weeks 5-7: Systematic testing revealing unexpected discrimination patterns
Weeks 8-9: Implementation of bias mitigation techniques and retesting
The exercise revealed that neutral-seeming variables, like commute distance or volunteer history, could unintentionally exclude protected groups.
Result

Bias reduction improved both system outcomes and candidate experience.
