Interviewing is a critical step in the hiring process for companies and it is the door of the passageway for an individual to enter a company/organization. All interviews should be a two-way street, with the opportunity for both parties to ask questions or learn more about the other, although often times, there is limited time for candidates to go real deep. You should always be prepared with at least one or two questions. There are techniques and methods utilized by organizations and executives to accomplish the fact finding and selection process.
Keep in mind that there are also different types of interviews. It is always best to prepare for the type of interview you will be facing. There is quite a bit of information, books, articles, blogs, tweets, etc., on this subject, and I recommend you perform your own search to go deeper into the type of interview ahead for you. In an effort to assist general research I have provided some articles on tips which you may find helpful as you prepare for your interview. This is certainly not an exhaustive list, but it is a good starting point.
