Diana:
A couple of questions that might help
Do you have a job now? If so, is the job you are interested in with the same company you currently work for?
What type of position is it?
What are the qualifications they are asking for and, out of those, which ones do you possess?
How many others are out there with these qualifications they are asking for?
Most companies will have a core set of qualifications for each position, those which you absolutely have to have in order to be able to function properly in the position. They also have a listing of "traits" that they want to see in any employee they might hire into any position with their company.
Many times those "must haves" are technical skills such as the ability to use a specific software program or experience in another technical area such as electrical etc. The other skills they are very interested in can be the "soft" skills such as a strong attention to detail or a solid customer service belief system.
Many times, job listings are quite broad and it can be a bit harder to figure out just what they are looking for. For example, a company might have a listing for someone with customer service experience and Word and Excel skills. At first blush one might not be able to tell just how much of the Word and Excel programs they would have to have a thorough working knowledge of. Many times the advanced functions of those programs are not used and a solid knowledge of the basic skills would be sufficient for this position. So if someone had a great deal of experience in customer service yet don't know ALL of Word and Excel, I would still hire them. And because "customer service" can encompass so much of what we do, it's a skill that you can demonstrate in an interview once you get the chance.
Maybe I can help if I know more about what type of position it is and more specifcs. It's what I've been doing for a living for over 20 years.
