Candidates are embedding hidden text and instructions in their resumes to game automated AI hiring platforms. This 'prompt hacking' tactic, reportedly found in up to 10% of applications by one firm, represents a new front in the cat-and-mouse game between applicants and the algorithms designed to filter them.

With HR departments using AI to screen candidates, a 'brag book' serves a new purpose beyond performance reviews. It becomes a critical repository of the quantifiable wins, keywords, and specific accomplishments needed to optimize a resume for automated hiring systems.

The purpose of quirky interview questions has evolved. Beyond just assessing personality, questions about non-work achievements or hypothetical scenarios are now used to jolt candidates out of scripted answers and expose those relying on mid-interview AI prompts for assistance.

Despite extensively using custom AI for interview analysis, Formation Bio finds that AI for candidate sourcing is still immature. Their talent team insists on a human reviewing every resume, highlighting that sourcing remains a significant automation challenge due to the need for nuance and confidence in evaluation.

Rather than creating assessments that prohibit AI use, hiring managers should embrace it. A candidate's ability to leverage tools like ChatGPT to complete a project is a more accurate predictor of their future impact than their ability to perform tasks without them.

Tools like Final Round AI provide candidates with live, verbatim answers to interview questions based on their resume and the job description. This development undermines the authenticity of remote interviews, creating a premium on face-to-face interactions where such tools cannot be used covertly.

When job applications are flooded with AI-generated resumes, they become meaningless. The way to stand out is to bypass the traditional application process by building a public portfolio of your work and expertise through content creation.

To build an AI-native team, shift the hiring process from reviewing resumes to evaluating portfolios of work. Ask candidates to demonstrate what they've built with AI, their favorite prompt techniques, and apps they wish they could create. This reveals practical skill over credentialism.

When companies use black-box AI for hiring, it creates a no-win 'arms race.' Applicants use prompt injection and other tricks to game the system, while companies build countermeasures to detect them. This escalatory cycle is a 'war of attrition' where the underlying goal of finding the right candidate is lost.
