The presentation is key to ace an interview. The Interview portion helps your future employers figure out if you can portray yourself, both in the company and outside of it, appropriately. If you truly want to ace the interview, you must act in a respectable manner. All employers look for respectful people to be in charge in the workforce, and it makes you seem much more convincing that you know what you are doing. Having confidence and interpersonal skills also makes you seem like a much more suitable addition to the workforce, as companies with these type of people are the most successful. No matter what, go in doing your best, and if you do not get the job the first time, you will experience for the next interview. Good Luck!
