Answer:
Research the company
Step-by-step explanation:
It is a good idea to find out information about the company you are interviewing. Among other things, this will help you decide if you actually want to work for that company.
Telling your current boss can be risky to your job. A new outfit may be helpful for certain positions--especially those where manner of dress is important. Finishing school may or may not be an important requirement for the position you're seeking. Your company research will tell you.
Researching the company is one of the most important steps to take.
