AI tools have made it easy for any candidate to produce a polished, keyword-matched résumé, and increasingly, to generate answers in real time during interviews and skills assessments. That means a strong résumé is no longer reliable evidence that someone can do the job, it’s evidence that they know how to present well. This piece looks at what employers should verify instead, and why firsthand knowledge of a candidate’s actual work is becoming the differentiator résumés used to be.
For years, a strong résumé was shorthand for a strong candidate. It signaled that someone knew how to present their experience clearly, which often correlated with how they’d present themselves on the job. That correlation is breaking down.
Generative AI tools can now rewrite a résumé’s language, align it with a job description’s exact keywords, and reframe ordinary experience to sound like specialized expertise, in seconds. The same tools are showing up during live assessments. SHRM recently reported on an analysis of nearly 20,000 interviews conducted between July 2025 and January 2026, which found that 38.5% showed signs of candidates using AI tools such as chatbots, coding assistants, and real-time response generators, with that figure climbing to 48% for technical roles. The concern isn’t just that candidates are using AI. It’s that hiring teams increasingly can’t tell what a candidate actually knows versus what a tool generated for them in the moment.
This isn’t really a story about résumé fraud. It’s a story about the declining information value of the résumé itself, and what employers should be checking instead.
A résumé has always been a candidate’s own account of their experience. What’s changed is how easily that account can now be optimized. AI can improve wording, tighten positioning, and match phrasing to whatever a job posting is looking for, regardless of how deep the underlying experience actually is.
That doesn’t make every well-written résumé misleading. Most candidates are describing real experience, just with better packaging. But it does mean that a well-written résumé is no longer reliable evidence of well-matched experience. When everyone can present well on paper, the résumé stops functioning as a differentiator and starts functioning as a baseline expectation.
There’s a meaningful gap between what a candidate claims and what a candidate has demonstrated. Claimed experience is a description. Demonstrated performance is evidence, something a manager observed, a client confirmed, or a delivered project can substantiate.
For most roles, that gap is manageable through structured interviews and reference checks. For specialized, project-based work like instructional design, facilitation, and learning strategy, the gap is wider, because the vocabulary of the field is easy to learn and much harder to apply well under real constraints: a tight timeline, a skeptical subject-matter expert, a learning management system with quirks nobody documented.
Before bringing on contract or full-time L&D talent, it’s worth verifying more than years of experience and a list of tools. A more reliable picture includes relevant project experience in a comparable industry or content area, subject-matter depth specific to the role, familiarity with the actual delivery environment and authoring tools your team uses, how the person communicates with stakeholders and subject-matter experts, reliability against deadlines, and the measurable results tied to past work.
None of that shows up cleanly on a résumé. Most of it only shows up when someone, or some organization, has actually watched the work happen.
Credentials answer “is this person qualified on paper.” They don’t answer “will this person deliver.” For that, employers need evidence that sits closer to the work itself: completed projects that resemble the one you’re hiring for, samples that show range and quality, direct feedback from past clients or managers, whether the person has been brought back for repeat engagements, and structured assessments or references that go beyond a generic recommendation letter.
Repeat engagements are one of the strongest signals available. A candidate can talk their way through a first project. Getting asked back for a second, third, or fourth one is much harder to fake.
L&D talent isn’t one job. An instructional designer, a facilitator, a learning strategist, an LMS administrator, and a technical trainer can all look similar in a candidate database search, and very different in practice. An instructional designer who excels at compliance content may struggle with scenario-based leadership training. A skilled in-person facilitator may not translate well to virtual delivery. A hiring manager without deep L&D expertise often has no reliable way to tell these differences apart from a résumé and a single interview, which is exactly why specialized evaluation matters more here than in most functional areas.
This is where firsthand knowledge becomes more valuable than a database of candidates. When a staffing partner has already placed a professional on real projects, that partner has something a résumé can’t provide: direct observation of how the person performs, how clients respond to them, and whether they get asked back.
TTA’s work with Edward Jones is a useful example. Over a two-year engagement, TTA deployed more than 30 instructional designers with financial services expertise to support continuing education, advisor development, and virtual training projects, building a scalable, on-demand L&D workforce rather than making one-off, résumé-driven hires for each new need. That kind of engagement isn’t built on interview performance. It’s built on a track record.
For organizations that don’t want to rebuild their vetting process from scratch every time a new project comes up, working through a staff augmentation model offers a practical alternative to recruiting project by project, because the vetting has already happened.
The résumé isn’t going away, and AI isn’t the villain here. But as it gets easier for anyone to present well on paper, “does this résumé look good” is no longer a useful filter on its own. The better question is simpler and harder to fake: what evidence tells us this person can deliver this work?
Organizations that can answer that question with real, observed performance, rather than polished self-description, will make better L&D hiring decisions in the years ahead.

Interviews and take-home assessments alone are no longer reliable, since AI tools can generate polished answers in real time. Look instead for evidence outside the résumé: work samples, completed projects, and feedback from people who have actually managed the person’s output.
AI can optimize a résumé’s wording and keyword match, and in some cases generate live answers during interviews and skills assessments. SHRM’s analysis of nearly 20,000 interviews found signs of this in 38.5% of cases overall, rising to 48% for technical roles, which is pushing employers toward assessments based on real work rather than standardized questions.
Relevant project experience, subject-matter depth, familiarity with your delivery environment and authoring tools, communication style, reliability, and documented results from past engagements. Certifications and years of experience are a starting point, not a substitute for this.
Evidence that the person has done comparable work before and done it well: completed projects, client feedback, and whether past clients or employers brought them back for additional work.
Match the evaluation to the specific type of work, not the job title. An instructional designer skilled in compliance content isn’t automatically strong at scenario-based leadership training, and a strong in-person facilitator doesn’t always translate to virtual delivery, so ask for samples and references tied to the exact kind of work you need.
References help, but they’re most useful when they speak to specific, observed performance rather than general impressions. Repeat engagements, where a client or employer chose to bring someone back for more work, tend to be a stronger signal than a reference call alone.
