Preparing for a job interview is more than just practicing common interview questions and choosing the right outfit. Mary Lorenz suggests the key things you should find out about a company before the job interview (See: What to research before a job):

What does the company do?
Hiring managers almost always ask what you know about the company in order to gauge your interest level and industry knowledge

What will the job entail?
You should try to understand as much as you can about the role prior to the interview. This will give you a chance to find out where you can contribute and prepare to discuss why you would be the ideal person for this role.

What are the company values?
It is not enough to know what the company does, but also why they do it. You will also see how it aligns with your own values and further assess whether or not this is the right company for you.

Who are the clients?
Who uses the company’s products and services? Showing you understand the company’s customers and their needs will further set you apart as a knowledgeable and enthusiastic candidate.

What is new and noteworthy?
Take the time to find out what the company has been up to lately, and you will get a better understanding of where the company is going and its place in the industry.

Who are the leaders?
Depending on the size of the company and the position for which you are interviewed, you may find yourself meeting with one of the leaders in person.

Who is your interviewer?
