The use of artificial intelligence (AI) in hiring and recruiting has advanced rapidly over the past decade. Various AI-powered software solutions are now leveraged by companies to automate parts of the candidate screening and interviewing process. These tools utilize natural language processing (NLP), computer vision, machine learning, and an array of algorithms to assess applicants.
Proponents argue AI brings much needed enhancements such as removing human biases, saving recruiter time, and gathering insights faster. However, critics point to risks around privacy violations, perpetuating algorithmic biases, over-automation, and questionable accuracy. The debate continues around the appropriate role for AI versus humans in recruiting.
In this comprehensive article, we will take a deeper look at how these AI recruiting platforms work, their purported benefits, potential downsides, and what the future may hold for AI’s expanding influence in hiring.
How AI Job Interview Software Works
AI recruiting tools aim to automate various stages of the hiring funnel, from initial screening all the way through job interviews. Here are some of the major features these platforms utilize:
Automated Interviewing With Chatbots
A main use case is leveraging chatbots or conversational AI to conduct automated interviews. Candidates respond to a series of interview questions posed by an AI assistant. These bots are designed using natural language processing to comprehend questions and responses, while machine learning algorithms help determine logical follow-up questions and discussions.
Advanced NLP techniques like latent semantic analysis and word embeddings are used to evaluate contextual meaning and sentiment behind responses. The bot aims to have a natural, back-and-forth dialogue while assessing qualities like critical thinking, communication skills, and relevant knowledge.
Platforms like Mya and Olivia use customizable bots to interview candidates over text or voice. The AI analyzes linguistic content, tone, word choice, and speed of responses. The automated assessments are then shared with recruiters.
Video and Audio Analysis
Along with NLP for analyzing verbal responses, some platforms apply computer vision and speech processing algorithms to video and audio interviews.
The AI reviews video footage of real or simulated interviews, studying visual cues like facial expressions, eye contact, and body language. Image recognition models identify faces and micro-expressions. The system evaluates how aspects like smile intensity, brow furrowing, and fidgeting may correlate with soft skills and emotional intelligence.
With audio from phone screens or video interviews, vocal analysis examines tone, pitch variability, pacing, and emphasis. AI can also transcribe the audio into text for linguistic assessment. Speakers with more dynamic speech patterns and warmer, energetic tones tend to score higher on traits like enthusiasm and extraversion.
Vendors like HireVue and Talview offer a mix of text, audio, and video analysis tailored to each hiring organization’s rubric. The AI captures thousands of data points to assess each candidate response.
Text Analysis Across Written Materials
Many platforms ingest a wide range of candidate authored text including resumes, LinkedIn profiles, cover letters, emails, and social media posts. These are parsed using natural language processing to extract linguistic signals correlated with skills, intelligence, creativity, leadership abilities, and cultural fit.
Specific techniques like topic modelling uncover main themes and concepts. Sentiment analysis reveals underlying attitudes and personality through positive and negative phrasing patterns. Linguistic style matching compares a candidate’s writing traits with existing top performers.
Startups like TrustSphere and Scoutible dig deeply into candidates’ digital footprints for clues around competencies, motives, and work habits.
Some AI tools incorporate game-like simulations as another evaluation mechanism. These interactive challenges test abilities like memory, processing speed, mental arithmetic, pattern recognition, and response accuracy. Games can appraise skills such as focus, multitasking, spatial reasoning, and adaptability in the face of dynamically changing problems.
Companies like Knack and Arctic Shores developed a variety of game-based assessments tailored to different roles and competencies. Performance metrics and gameplay behaviors offer predictive insights around potential job success.
The most robust AI recruitment platforms combine all of the above modalities – text, speech, video, and games – into a consolidated analysis. Each mode provides distinct signals that feed into machine learning algorithms to generate an integrated candidate profile.
Vendors tout multimodal analysis as the most accurate and least biased technique. For example, gaps found in language mastery assessed through games can be cross-checked against a candidate’s eloquent resume. The AI looks for consistency and synergy across modalities to deliver more holistic insights.
Pros of Using AI Job Interview Software
Let’s examine some of the claimed benefits driving adoption of AI recruiting tools:
Mitigates Unconscious Human Biases
By automating steps like resume screening and interviews, AI systems apply consistent, empirical evaluations that avoid human biases around race, gender, age, attractiveness, alma mater, and other irrelevant factors.
Algorithmic assessments based purely on data inputs like skills, experience, and assessment performance promote diversity and equal opportunity. AI helps reduce the subjectivity and “gut instincts” that can creep into human hiring decisions.
Saves Significant Recruiter Time
HR analysts estimate that recruiters spend between 30-60 minutes per candidate for screening calls and interviews. For roles with hundreds of applicants, this adds up to hundreds of hours of repetitive interviews.
AI recruiting chatbots allow recruiters to outsource the high-volume early stage screening. This frees up their time for higher value tasks like building partnerships, consulting on complex roles, and focusing on closing top candidates.
Analyzes Larger Candidate Pools
While human recruiters face constraints around how many people they can screen and interview, AI bots have no such limitations. Software allows companies to cast a much wider net by assessing vast candidate pools quickly and cheaply.
Widening the hiring funnel provides access to more qualified applicants and talent that may have otherwise slipped through the cracks. This supports efforts to enhance diversity.
Speeds Up Insights on Candidates
Manually gathering insights on candidates typically takes weeks or months as the hiring process plays out through multiple stages. AI aims to provide quicker insights by combining past performance data with assessments of video interviews, texts, and games.
Predictions around work habits, problem solving abilities, and culture fit enables recruiters to identify red flags or make competitive offers faster.
Scalable Screening at Lower Costs
Humans do not scale cost effectively to handle high application volumes. But AI recruiting platforms offer automated screening that is scalable at very low marginal costs. Once infrastructure is built, adding another 10 or 100 candidates costs very little.
This scalability enhances applicant tracking systems by adding an automated layer to screen candidates before they reach human reviewers.
Available 24/7 for Candidate Convenience
Scheduling live interviews forces candidates to align their availability with a recruiter’s calendar. Automated bots allow applicants to complete self-scheduled video interviews or chat screens anytime.
Around the clock availability improves the candidate experience and completion rates. People can interact with the AI at their convenience rather than being constrained to business hours.
Risks and Downsides of Using AI in Hiring
Despite the upsides, experts and critics point to many potential pitfalls and risks to using AI in recruiting:
Privacy Concerns Over Extensive Data Gathering
AI recruiting tools ingest far more data on job applicants than traditional hiring processes. The depth of personal details extracted from sources like social media, texts, and video interviews raise concerns around ethical boundaries and privacy violations.
Critics argue these AI systems often extract excessively personal insights unrelated to job skills, like detecting a candidate’s mood or personality. More regulation may be needed as to what candidate data can ethically be analyzed.
Potential to Perpetuate Biases
While AI promises to reduce human bias, the machine learning models are only as good as the training data. If that data reflects societal or historical prejudices around factors like race and gender, the algorithms will perpetuate those biases.
For example, AI taught to score assertive communication positively may give lower marks to equally valid cultural differences. Rigorous audits and testing are required to combat biased data and algorithms.
Assesses Narrow Range of Traits
The current state of artificial intelligence remains limited, unable to fully understand complex human psychology and behavior. Critics argue the automated assessments only evaluate a narrow set of traits like basic cognition versus deeper competencies.
Interpersonal skills, strategic thinking, creativity, leadership qualities, and other soft skills remain difficult to accurately score with today’s NLP and image recognition capabilities.
Over-Automation Reduces Human Interaction
A major critique is that relying too heavily on AI in recruiting leads to over-automation that leaves candidates feeling dehumanized. Human discretion and conversations are still vital.
Candidates resent being judged solely by what is often perceived as an opaque algorithm versus having the opportunity to connect with real recruiters. Finding the right balance between human and machine is key in hiring.
Harder to Gauge Culture Fit
Data-driven algorithms have a difficult time qualitatively assessing how well a candidate’s values, style, and personality fit with company culture. But culture fit remains a top priority for employers.
Subtler aspects like sense of humor, communication style, and ability to collaborate are best evaluated through human interactions versus AI screening tools. Qualitative assessments still require a human element.
Questionable Accuracy and ROI
While vendors promise that AI will enhance recruiting results, the actual return on investment remains unproven. A major study by Harvard and University of Toronto found AI was no better than untrained humans at predicting job success.
More research is still needed to support claims that algorithmic assessments translate to tangible improvements in quality of hire, retention, and performance. The jury is still out on accuracy.
The Future of AI in Recruiting and Hiring
Given the debate around risks versus benefits, what is the realistic future role for AI as technology continues advancing?
Blending AI With Human Interactions
Rather than a pure automation approach, the ideal scenario blends automated screening with human interactions later in the funnel. This hybrid system benefits from the scalability of AI while retaining human conversations.
For instance, top candidates selected by the algorithms still proceed to Skype interviews with real recruiters. This provides the best of both worlds – automation with a human touch.
Ongoing Audits for Fairness
More rigorous auditing processes will be imperative to ensure unbiased models, similar to testing done in financial services and healthcare. Analytics need to monitor for discriminatory outcomes across gender, race, age groups and other demographics to meet ethical AI standards.
Transparency and Explainability
Today’s black box models offer little visibility into why certain candidates are screened out. Advances in explainable AI will be crucial for illuminating what candidate attributes and assessments are driving hiring decisions.
Improved model interpretability will enhance transparency and trust in algorithmic recruiting. Both candidates and employers benefit from understanding assessments.
Rise of Multimodal Analysis
AI that analyzes multiple signals – text, speech, video, and simulations – provides a more well-rounded profile than any single source of data alone.
Expect integration of multimodal analysis into most platforms as the technology matures. Multimodal provides richer candidate insights by removing blindspots from any one domain.
Integration Into Existing Platforms
Rather than stand-alone products, AI assessments will increasingly be embedded directly into existing hiring sites and applicant tracking systems.
For example, LinkedIn’s talent marketplace could partner with AI providers so relevant screening and bots are integrated seamlessly into the LinkedIn experience.
Like many emerging technologies affecting people’s lives, governments will likely step in with appropriate regulation around transparency, ethics, and privacy. Expect rules comparable to financial AI algorithmic auditing.
Forward-looking companies will proactively monitor AI recruiting for unintentional biases long before regulations mandate it. Those failing to self-govern put themselves at compliance risk.
The application of AI and automation to recruiting holds both significant opportunities and risks. Algorithmic assessments promise to widen the hiring funnel, save recruiter time, reduce biases, and gather insights faster on candidates. However, legitimate concerns remain around privacy, perpetuating biases, lack of human interaction, and unproven ROI.
Current AI technology still lacks the sophistication to replicate human judgment on many soft skills. Finding the right balance between automation versus human assessment will be key in getting the most value from AI recruiting tools.
Blending algorithms with ongoing human interactions can maximize the upside while mitigating the downsides. Wise adopters will proactively monitor for biases and ensure transparent, ethical usage.
As artificial intelligence continues progressing alongside appropriate governance, the future role of AI in hiring seems likely to expand. However, successful employers will thoughtfully augment rather than fully replace the irreplaceable human element in recruiting.
