When you’re interviewing, you can bet that you’re being evaluated on your soft skills. That means the people interviewing you are evaluating how you’re interacting with them. If they don’t like you and how you’re interacting, you won’t get the offer, regardless of your talent. That’s why you must approach the entire interview process with a positive attitude.
