The interviewing process can be very intimidating if you don't know what to expect.
All interviews fit a general pattern.
The typical interview will last 30 minutes, although some may be longer. The key to successful interviewing is preparation. It is important that you know as much as possible about the position for which you are applying and the organization with which you are interviewing. Thoroughly research the organization, career field, issues and trends related to the type of work you would be doing. You will be expected to articulate your goals, values, interests, and skills.
