A common hiring mistake is searching for generic talent. The true skill is assessing a candidate's inherent characteristics to determine if they can thrive in your company's unique culture and pace. The critical question isn't if they're a great employee, but if they can be a great employee *for you*.

To avoid the trap of hiring 'good enough' people, make the interview panel explicitly state which current employee the candidate surpasses. This forces a concrete comparison and ensures every new hire actively raises the company's overall talent level, preventing a slow, imperceptible decline in quality.

Use the maxim, "How someone does anything tells you how they do everything." Assess a candidate's preparation for the interview itself. Their research, note-taking, and follow-up are direct predictors of their future diligence and performance in the role.

To find PMs who are thoughtful and prepared, share interview questions beforehand. This shifts the evaluation from quick thinking under pressure to the candidate's ability to prepare, research, and structure their thoughts—skills more critical for the actual role.

To scale hiring efficiently, eliminate ambiguity. Each interviewer must make a definitive 'yes' or 'no' decision. If an interviewer is 'not sure' after their session, they are the problem, not the candidate. This prevents endless interview loops and forces clear, decisive judgment.

To improve candidate experience and evaluation quality, Formation Bio structures its interview process by assigning distinct key competencies to each interviewer. This ensures every conversation is unique and valuable, preventing the common problem of candidates repeating the same stories to different team members.

Ineffective interviews try to catch candidates failing. A better approach models a collaborative rally: see how they handle challenging questions and if they can return the ball effectively. The goal is to simulate real-world problem-solving, not just grill them under pressure.

Elite hiring processes are bespoke and ad-hoc, not rigidly consistent. Treat the candidate as the atomic unit, not the job description. This means tailoring the interview experience—from who they meet to the topics discussed—to that specific person, rather than forcing everyone through an identical, robotic process.

The strong impression from a job interview creates a false sense of 'knowing' who will be a good hire. This vivid, face-to-face interaction leads managers to overweight its value and discount more predictive data. Adding an unstructured interview can therefore make hiring predictions worse than using objective data alone.
