Large Language Models, or LLMs, are the engines that have driven some of the biggest technological advancements in recent years. OpenAI’s GPT-4, Google’s Bard, and Metas Llama are examples of LLMs that power interfaces like ChatGPT, which has changed how many of us work and manage aspects of our daily lives.
At Sapia.ai, we use responsible AI to help organizations find the people who belong with their brands. Chat Interview™ enables our customers to interview every candidate, widening their talent pools and creating a more efficient, effective, and fair recruitment process.
With the advent of LLMs with enhanced language understanding and reasoning, there is a promising opportunity to extend these models in the recruitment space. However, using LLMs for activities like interview scoring demands not only innovation but also a strong commitment to responsible use and ethics. Any use of technology to make hiring more efficient should also make it fairer and transparent.
This blog post summarises the paper that we presented at SIOP 2024, titled “Responsible Use of Large Language Models for Response Grading and Explanations in Structured Interviews”, written by Yimeng Dai, Leo Pham, Ashlie Plants, and Buddhi Jayatilleke.
Our goal was to create an LLM that could grasp the unique nuances of interview conversations, leading to the creation of InterviewLLM. This domain-specific model was trained on a rich dataset from our Chat Interview™ platform, encompassing over 1.3 billion words from diverse industries, job roles, and geographies. The result is a model that can understand and generate interview dialogues with fewer possible stereotypes.
Building on the capabilities of InterviewLLM, we developed Saige™ (Sapia AI for Interview Grading and Explanations), a tool that takes interview grading to new heights. Saige™ is fine-tuned with a grading rubric crafted by our subject matter experts, employing Behaviorally Anchored Rating Scales (BARS) to ensure that assessments of candidate responses are anchored in the description of observable behaviors. By adopting BARS, the gold standard for creating rubrics for scoring interviews by humans, Saige™ allows human SMEs to add new competencies to be rated by Saige™, which most of the current mainstream automated interview grading approaches lack.
We didn’t stop at creating a more intelligent grading system with extensibility and explainability. Using LLMs in interviews demands a strong ethical commitment. We recognized the importance of addressing potential biases in AI, which led us to implement a de-biasing process during Saige™’s training. By combining the expertise of our human SMEs with AI feedback, we created a model that not only delivers accurate grades but does so in a manner that is fair and objective.
Saige™ also leverages LLM to explain why a candidate received a certain score, referencing actual examples from the candidate’s response and a description of how it exemplifies or fails to exemplify, the characteristics of the attribute that were defined by the SMEs. The characteristics of each attribute are defined by not only the many facets of them but also the frequency and depth in which they are demonstrated.
The introduction of Saige™ marks a significant milestone in the recruitment industry. In testing, Saige™ has demonstrated exceptional performance compared to LLaMA-2, with a higher agreement and correlation with SME grading.
The implications of Saige™ extend beyond just improved interview grading accuracy. By reducing biases in the grading process, we’re contributing to a more equitable hiring process, where candidates are evaluated based on their merits rather than unconscious prejudices.
Saige™’s ability to provide clear, natural language explanations for grading decisions creates a level of transparency not seen before in automated interviews. With the explanations, candidates can gain insights into areas for improvement and identify the attributes or abilities necessary for success in their careers; while hiring teams can learn more about each candidate and have confidence in their hiring decisions.
We’re at the start of our journey with InterviewLLM and Saige™. The opportunity to use this capability beyond assessment, to provide effective coaching to candidates and employees at scale is immense and exciting. It could enable them to understand how they can improve, fostering continuous growth and professional development within the organization. As we continue to refine these Generative AI tools and explore new applications of LLMs in recruitment, we remain committed to our core principles of fairness and transparency.
Retail leaders have embraced AI to improve supply chains, automate checkout, and enhance customer experience. But what about finding the people who deliver that customer experience?
AI brings incredible possibilities to supercharge how retailers hire, develop, and retain talent.
At Sapia.ai, we helped iconic retailers like Woolworths, Starbucks, Holland & Barrett, and David Jones reimagine hiring from the ground up – replacing resumes, ghosting, and gut feel with structured, ethical AI that delivers performance and fairness at scale.
The Retail Problem: Volume, Turnover, and Ghosting

We can’t hide from reality anymore. Talent needs are shifting overnight, and AI is redefining what it means to work. Traditional talent frameworks are no longer fit for purpose. At Sapia.ai, we believe the future of talent strategy lies in a smarter, fairer, and more adaptive way of defining what great looks like.
Our AI hiring platform is built on the largest proprietary dataset of interview answers globally – we’re a data company at heart, and we’ve seen the power of data-driven people methodology in transforming how organisations hire and retain good talent.
So, when it came to building a new Competency Framework that could be leveraged globally for hiring for any role at any scale, of course, we used a ground-up, data-led methodology that bridges the gap between organisational psychology and AI.
Conventional frameworks are typically crafted through expert interviews and focus groups. While valuable, they tend to be subjective, static, and too slow to keep pace with evolving job demands. As roles become more fluid and technology augments or replaces task-based skills, organisations need a new way to understand the human capabilities that genuinely matter for performance.
We wanted to identify enduring, job-agnostic competencies that reflect what drives success in a modern workplace – capabilities like adaptability, resilience, learning agility, and customer orientation.
(Why competencies and not just skills? Read why here.)
Sapia.ai’s methodology is rooted in the science of human behaviour but powered by cutting-edge AI. We asked two core questions:
The answer to both: yes.
We began with a rich dataset of over 37,000 job descriptions across industries and role types. Using large language models (LLMs) and advanced NLP techniques, we extracted over 200,000 behavioural descriptors. These were distilled down through a four-step process:
This resulted in a refined list of 25 human-centric competencies, each with clear behavioural indicators and practical relevance across a wide range of roles.
Our framework is intelligent, but importantly, it’s adaptive. Organisations can apply this methodology to their own job descriptions to discover custom competencies. This bottom-up, role-data-led approach ensures alignment to real work, not just theoretical models.
And because the framework integrates directly with our AI-powered hiring tools, you get a connected system that brings your talent strategy to life.
Our framework comes to life in the following tools:
Skills alone cannot predict success. Competencies do. As AI continues transforming how we work, Sapia.ai’s Competency Framework offers a scalable, scientific, and fair foundation for hiring and developing the talent of tomorrow.
If you’re a CHRO or Head of Recruitment at an enterprise today, chances are you’ve been inundated with messages about the importance of “skills-based hiring.” LinkedIn’s recent Work Change Report (2025) is full of compelling data: a 140% increase in the rate at which professionals are adding new skills to their profiles since 2022, and a projection that by 2030, 70% of the skills used in most jobs today will have changed.
This is essential reading. But there’s a missed opportunity: the singular focus on “skills” fails to acknowledge the real metric that talent leaders need to be using to future-proof their workforce — competencies.
But skills on their own — even soft ones — are generic, disjointed, and often disconnected from real-world performance. In contrast:
Put simply, competencies answer the all-important question: Can this person apply the right skills, in the right way, at the right time, to deliver results in our environment?
The Work Change Report outlines a future where job titles are fluid, roles evolve quickly, and AI is a constant disruptor. This creates three massive challenges for hiring at scale:
Skills alone don’t tell us whether someone can succeed in a role that will look different 12 months from now. But competencies can. Because they measure not just what a person knows, but how they apply it.
The LinkedIn report highlights a critical insight: organisations now prioritise agility in entry-level hiring. And there’s a good reason for that. With professionals expected to hold twice as many jobs over their careers compared to 15 years ago, adaptability is not just a nice-to-have. It’s core to success.
But you can’t measure agility with a keyword on a CV. You measure it by looking at competencies like:
When you shift the focus away from skills to behavioural competencies that can be defined, observed, and assessed in structured ways, you open yourself up to a much more dynamic and more useful way of managing talent.
To hire effectively at scale, particularly in a technology-driven world of work, talent leaders must shift their lens:
LinkedIn’s data shows that people are learning more skills more quickly than ever. But the real question for talent leaders like you is: Are those skills being applied in ways that drive value? Are we hiring for task proficiency or performance?
The truth is that the organisations that will thrive in an AI-driven, skills-fluid economy aren’t the ones chasing the next hot skill. They’re the ones designing systems to identify, develop and scale competence.
