Don’t try to be perfect
During an interview you’re likely to be asked about your biggest weakness, or to tell the interviewer about a time when you failed. You should have honest, real-world examples of these situations ready to go if the question arises. What you don’t want to do is say you have no flaws, or that you’ve never failed. This makes you seem either arrogant, or unable to accept responsibility for your part in setbacks. A potential employer will want to know how you respond to adversity, and trying to convince them that you’ve never faced adversity will not make you seem like the perfect candidate, it will make you seem unprepared for the curveballs that can come in a business setting.
