Don't just sit there. Ideally, an interview should be a two-way exchange of information. Remember, the interviewer's objective is to find out if you are a person the organization would like to hire. Your objective is to find out if this is a place where you would want to work. Prove you are worth the risk.
Employers take a chance when hiring a new person.
The interviewer will need assurance that you want the job and will not leave too soon after accepting an offer. Highlight intangible qualities like teamwork and flexibility to show that you work well with others. Turn negatives into positives. As a recent graduate, you will need to convince employers that you have the right experience to competently perform the job and can learn quickly. Do your homework.
