The Résumé Was Perfect. The Hire Wasn't?

The résumé was flawless, the interview effortless. Everyone in the room agreed: the right hire for the leadership role. Six months later, the org chart looks the same, but the mood on the team has noticeably soured. This is exactly the pattern behind many disappointing hiring decisions: it was rarely a question of missing qualifications. The decision gets made in a handful of conversations. The consequences only surface months later, with a far bigger price tag attached.

Why a Good Conversation Promises So Little

A classic interview shows one thing above all: how someone presents themselves in a conversation with strangers. A study in the Journal of Applied Psychology recently recalculated the predictive power of various selection methods: unstructured interviews, the classic free-flowing conversation, reach a predictive validity of just 0.19 for later job performance. Structured interviews with fixed questions and scoring grids reach 0.42, more than double.¹ The difference isn't down to the interviewers' talent. It's because charm, confidence, and a forceful presence shape a conversation in someone's favor. But those same traits reveal very little about how someone reacts when things get genuinely difficult over months. An interview can create a positive impression in a short amount of time. But how does a candidate act on a bad day, or under real stress?

What Only Becomes Visible Later

As we described in our article on leadership as a potential burden, the qualities that create a positive impression during an interview may become less effective when overused or displayed under pressure. Self-confidence may be perceived as overconfidence, while attention to detail may be perceived by others as perfectionism or micromanagement. Hogan Assessments refers to such potential behavioral risks as “derailers.”² Because a single interview provides a limited insight into how someone may behave under sustained pressure, a scientifically grounded personality assessment can offer valuable additional information. Used alongside interviews, experience and other relevant evidence, it can help identify and explore these risks before a person takes on a leadership role.

What the Mavie Stress Study 2026 Shows About Leadership

Just how real this pattern already is in Austrian companies is shown very clearly by the numbers from the Mavie Stress Study. More than half of employees often see their own manager as visibly stressed.³ That isn't without consequences. For nearly a third, this noticeably reduces their enjoyment of their own work. One in five thinks more often about changing jobs as a result.³ Crucially, this is no longer just a concern: a quarter of respondents have actually quit a job at least once because of their manager's behavior.³ Poor leadership is therefore no longer an abstract risk, but a concrete driver of turnover intentions and actual attrition. Whoever fills a leadership role isn't just deciding who gets the job, but how the team will function afterward.

A Bad Hire Costs More Than the Hire Itself

The first price is substantial: according to the Society for Human Resource Management, replacing a specialist or a manager costs between 50 and 200 percent of their annual salary, depending on the role. Leadership roles tend to sit at the upper end, due to lost expertise and client relationships.⁴ But the calculation doesn't end there, as the numbers above show: a single bad hire quickly turns into a multiple of costs. The role itself has to be replaced. The team's performance already declines in the meantime. And some employees end up actually quitting, not because of their own job, but because of the person who was supposed to provide direction. An org chart may look right on paper. Whether the team behind it actually functions is decided somewhere else entirely, and in the end it isn't only the manager who pays for that, but the whole company.

Taking the Right Steps Before Signing

The good news is that this aspect of decision-making can be strengthened while ensuring a fair and respectful candidate experience. It is not about distrusting applicants, but about complementing personal impressions with reliable, scientifically grounded data. Workplace personality assessments can provide insight into how someone may behave under pressure, for example, by becoming more withdrawn, controlling, or eager to accommodate others. Identifying these potential behavioral risks early enables them to be explored before they affect day-to-day leadership and team effectiveness. Companies that approach leadership selection thoughtfully and support their teams throughout the process can reduce the costs associated with unsuccessful hires while strengthening their attractiveness as employers. Ultimately, a sound decision is based not on one successful interview, but on a more complete picture of the candidate.

The Point to Consider Before the Next Decision

Qualifications can be reviewed in a CV. Potential behavior under pressure is more difficult to assess. Yet this can significantly influence whether a leader supports or places additional strain on their team. Our own results from the Mavie Stress Study 2026 show that this difference is long past being theory: visible stress in a manager goes hand in hand with declining enjoyment of work, lower performance and resignations.³ What is overlooked during selection may be more difficult to address afterwards. That makes it all the more important to look closely at the point of hiring. So before the next important people decision, one simple question is worth asking: do you rely on a good conversation, or complement it with data offering insight into how the candidate may behave when under pressure?
