Hard Skills vs Soft Skills: Two Complementary Pillars

Hard skills allow you to be hired. Soft skills allow you to succeed and progress. Good recruitment always balances both dimensions according to the role's importance.

Definition of hard skills

Hard skills, or technical competencies, refer to all measurable and objectively verifiable professional expertise acquired through education, practice or experience. They include IT skills, certifications, regulatory qualifications and industry-specific methods.

Unlike soft skills, hard skills can be measured, tested and learnt in relatively standardised ways.

FAQ – Hard Skills

Can you recruit someone without all required hard skills?
Yes, if the person has absolutely critical skills and strong learning capacity. Assess the time and cost to fill the gap. For a junior or career changer, accepting gaps on secondary hard skills is normal. For a senior, expectations are higher.
How to verify a candidate isn't lying about hard skills?
Use practical tests and in-depth questions. Someone who truly masters a skill can explain how they used it concretely, difficulties encountered and possible alternatives. Be wary of vague or overly theoretical answers. Professional references are an excellent validation method.
Is an expert or versatile profile better for SMEs?
In SMEs with small teams, versatility is often more valuable. For a highly specialised role with complex technical challenges, deep expertise is essential. The ideal is often a T-shaped profile: strong expertise in one area plus broad skills in adjacent areas.
How to manage obsolescence of tech hard skills?
Some hard skills (development, digital marketing) have a 3 to 5-year lifespan. Prioritise learning capacity, invest in continuous training, and value profiles able to adapt. Anticipate tomorrow's skills from today's recruitment.
