The short answer
The first month reveals whether the job promise matched the actual role. Focus on three things: does the new employee understand the tasks as expected, does onboarding reflect what was promised, and do the selection criteria hold up in hindsight? Performance after one month says little about recruitment quality – context and settling-in time both matter.
Bring one vacancy. In 30 minutes, we discuss where your recruitment is getting stuck, which approach could fit and your recruitment fee.
Job promise versus daily reality
A job advert sets expectations. The first weeks show whether those expectations hold. Ask your new employee directly: which tasks surprised you, positively or negatively? Significant gaps between promise and practice point to a mismatch in the advert or interview – not necessarily to the wrong candidate.
Onboarding quality as a separate variable
A rocky start does not always reflect the quality of your selection. Is there no induction plan, are colleagues overstretched, or is the workspace not ready? These factors affect the experience independently of who you hired. Assess onboarding quality separately from selection criteria, so improvements land in the right place.
Testing your selection criteria in hindsight
After four weeks, look back: which criteria from the selection process proved relevant, and which did not? A practical example: you selected on AutoCAD experience, but the employee spends most of their time coordinating with subcontractors. Communication skills then become a criterion you weight earlier next time. Every placement becomes a learning opportunity.
A practical feedback conversation
Schedule a short conversation between line manager and new employee around day twenty. Use three questions: what was different from expectations, what was missing from the preparation, and what do you need for a strong second month? The answers give you concrete input for your recruitment process – without treating one-month performance as a benchmark.
From feedback to sharper hiring
Record the insights and discuss them with everyone involved in the hire. Red Rocket combines organisational context, campaigns and an AI recruiter so expectations are clear well before day one.

Frequently asked questions
Can I conclude after one month that a hire has failed?
Do not draw that conclusion solely because a month has passed. Examine the specific signals, selection criteria and quality of support. A problem may require action, but a short period of employment does not automatically establish its cause.
Who conducts the feedback conversation?
The manager or recruiter involved in the placement can lead the conversation. Involve the employee in explaining and using the feedback, and handle any personal data under the recorded arrangements.
How do I apply the insights to the next vacancy?
Note for each criterion whether it proved relevant in practice. Adjust the job advert and interview format based on those notes. That way your recruitment process becomes a little sharper after every placement.
