What does supplementary skills refer to in recruitment?

• A. Similar knowledge, skills, abilities, and other characteristics to those already on the team
• B. Completely new skill sets outside the team
• C. Performance metrics for evaluation
• D. Required certifications for new roles

Answer: (A)

Supplementary skills are abilities that reinforce and extend what the team already does, by adding capabilities that fit with the existing mix of knowledge and processes. The idea is to bring in someone who shares similar knowledge, skills, and characteristics to current team members so they can plug in smoothly, collaborate effectively, and quickly contribute without a steep learning curve. This helps maintain workflow, cohesion, and predictability in how work gets done.

Hiring someone with similar expertise to what the team already has prevents shifting the team’s direction into a new domain, which would be more about adding completely new skill sets rather than strengthening what's already in place. Performance metrics for evaluation and required certifications are not the skills themselves—they’re about measuring performance or qualifying for a role, not about expanding or aligning the team’s current capabilities.
