A briefcase or portfolio should be used to carry your extra resumes and note pad. Wait until you are hired before examining the dress code. Before attending an interview, make an appointment with a counselor at your university's placement office or career center. Wear your interview attire. Present your credentials as if you were in an actual interview.
Role play some previously difficult conversations.
Ask for feedback on your appearance and responses. While preparing for actual interviews, send or fax your resume in advance, with a cover letter emphasizing your credentials and work experience. Research each organization and prepare a list of questions and answers to use in the meeting. During the interview, focus on the interviewer, the job requirements, and the company's needs. Hopefully, by thorough preparation, you will be taken seriously.
