What a strong example might demonstrate

Candidates preparing for competency-based interviews can use this competency to think about work where accuracy mattered and errors would have had real consequences. A strong behavioural example would demonstrate the expertise applied, the checks put in place, and the outcome.

How to prepare for questions on this competency

Because ICC roles are often highly specialised, professionalism is generally explored through the technical substance of past work and the way quality was assured.

STAR preparation

  • Situation — set the context in two sentences: where, when, who was involved.
  • Task — state precisely what you were responsible for, not what the team was responsible for.
  • Action — spend most of the answer here, in the first person, showing the indicators above in practice.
  • Result — quantify the outcome and add what you learned or changed afterwards.

Common mistakes

  • Generic answers that could apply to any employer
  • No evidence of quality control
  • Overstating expertise that will be probed by a specialist panel
