Applying to multiple jobs? You may want to think about tweaking your resume.
Things to keep in mind:
Research the company and industry prior to your interview. Know a little company history beforehand will show that you are interested and invested.
Mock Interview Questions
First impressions count, especially with your initial interview. Studies have shown that first impressions are made within seconds of first meeting someone. That's why you should always follow business professional attire for a job interview.
Do test-drive an outfit to ensure it fits well the night before the interview.
Exception to the Rule!
For professionals in creative fields such as marketing and advertising - the interview attire can be flexible. It all depends on the company itself and the culture. If you are in doubt, contact the hiring manager prior to the interview.
