There are two primary types of interviews used by companies: screening interviews, and selection interviews. Every company's hiring process is different. Some companies may require only two interviews while others may require three or more. It is also not uncommon to see a company conduct testing (personality, skills based, aptitude, etc.) as an intermediate step in the hiring process.
Here is an overview of the major types of interviews and tips on how to handle them:
SCREENING INTERVIEWS ~
Your first interview with a company will often be a screening interview. The purpose of a screening interview is to ensure that prospective candidates meet the basic qualifications for a given position. It may take place in person or on the telephone. If you meet the basic qualifications, express interest in the position, and make a positive impression on the interviewer, you will likely be selected for a selection interview.
Selection interviews are typically conducted onsite at the hiring company. The purpose of a selection interview is to determine whether a candidate will be selected for the position he or she is interviewing for. A selection interview is typically more rigorous than a screening interview. At this point, a company is trying to decide whether or not you should either be moved to the next step in the hiring process or an offer is going to be extended, so there will be more scrutiny than with a screening interview. The company wants to know - Are you qualified for the job? Are you a good cultural fit? Can you make an immediate impact, or will you need extensive training? Questions will be more specific and your answers will need to be more detailed.
