Balance your confidence
You should always be confident in your experience and abilities during an interview. However, being overly confident or cocky can be a detriment to your chances. Employers will ask you some tough questions, and depending on the job, they can be very technical or specific about programs and processes. Don’t pretend to be familiar with topics when you only have a loose understanding. That can force you into a situation where you’re asked follow-up questions that you’re not comfortable answering, or even worse, presenting false information as fast. It’s important to be confident in what you know, but don’t be afraid to admit when you don’t know sometime and offer to look deeper into the topic after the interview.
