Make your strengths relevant to the role you are interviewing for. Give specific examples that will lend well to the role. For instance, if interviewing for a sales role, speak about your KPIs, targets and specific sales achievements. Avoid cheating and describing a personality trait, but focus on a professional one. Instead of “I am really funny and make people laugh”, talk about being a team player and leader. In regards to answering what is your greatest weakness, keep it positive, and focus on challenges you have overcome.
