I would say have at least two examples for each competency. Because interviewers can ask about one specific competency in difficult ways. E.g. tell me about a time when you’ve successfully worked in a team and then ask tell me about a time when you worked in a team and you had a disruptive team member.For competency questions, does anyone know whether you should use multiple examples of the competency (e.g., 3 x STAR), or should you just focus on developing one example well?
